Description

  Embodiments of the present invention relate to computer technology, and more particularly, to methods, systems and apparatus for cloud application redundancy.

  If a computer system suffers from overwhelming disasters such as fires, floods, earthquakes, and wars, cloud applications can be interrupted if effective measures are not taken, and all data is It can also be lost in computer systems, which results in significant losses. Redundancy techniques can effectively cope with the surrounding environment, and in particular, the impact on the computer system from the time of a disaster. In the event of a disaster, redundancy techniques may back up data at production sites to redundant sites, such assuring user data security and high system availability.

  Virtualization technology can integrate multiple operating systems into one high performance server to maximize utilization of all resources of the hardware module to implement more cloud applications with less investment. This can not only simplify the system architecture but also reduce the difficulty of resource management, so that the technology is widely applied to computer systems. At present, the prior art mainly uses the following manner to implement redundancy for cloud applications running on a virtualized computer system.

  The administrator determines the virtual machine included in the cloud application needing redundancy, that is, the administrator specifies the redundancy required virtual machine and then virtualizes it at the next operation site. Query the module to determine the storage unit being used by the redundant virtual machine, and configure the corresponding storage unit at the redundant site for the redundant virtual machine, so that the redundant site needs redundant Data in storage units being used by a virtualized virtual machine can be replicated to corresponding storage units at redundant sites.

  If it is necessary to perform redundancy for the operation site, create virtual machines on the redundant site and manually perform operation on the virtual machines for which the corresponding settings have been created, eg, set the corresponding networks, as a result, The storage and network of virtual machines requiring redundancy can be restored to redundant sites, achieving virtualized redundancy of operating sites.

  In the prior art, when recovering a redundancy-required virtual machine at a production site, an administrator designates a virtual machine to perform backup and recovery that will be implemented for redundancy. Because cloud applications are deployed to multiple virtual machines, some virtual machines will not be recovered if some virtual machines are not specified when specifying a virtual machine that requires redundancy. Eventually, it will not be possible to recover the cloud application completely. In addition, in the prior art, in the recovery process of virtual machines, it is necessary to manually set up networks of virtual machines one by one, and the recovery process of multiple virtual machines is time-consuming and inefficient.

  Embodiments of the present invention propose a method, system and apparatus for cloud application redundancy that can restore cloud applications completely and quickly at redundant sites.

Method of Redundancy FIGS. 1 (a), 1 (b), and 1 (c) are block diagrams of systems provided by embodiments of the present invention. The system comprises a production site (100) and a redundant site (110), where the production site (100) provides services for at least one cloud application and a redundant site (110) at the production site Required to recover redundant cloud applications. The active site (100) and the redundant site (110) are relative concepts. The active site (100) represents a site where the cloud application is operating before recovery, and the redundant site (110) represents a site where the cloud application is operating after recovery. The active site (100) and the redundant site (110) may be differentiated according to local location, eg Beijing site and Xi'an site, or may be differentiated according to different rules.

  The operating site (100) and the redundant site (110) each have at least one data center, as shown in, for example, FIG. 1 (a), FIG. 1 (b) and FIG. 1 (c). The active site (100) comprises a data center (101) and the redundant site (110) comprises a data center (111). The data center may comprise a physical server, where the physical server may be configured to provide computation, storage and network resources to a production or redundant site. Physical servers configured to provide computation and network resources may be referred to as computing nodes, and physical servers configured to provide storage resources may be referred to as storage nodes. For example, the storage node (102), the storage node (112), the computing node (103), and the computing node (113) shown in FIG. In the example shown in FIG. 1, the production site (100) and the redundant site (110) each have one data center, and each data center has one computing node and one storage node. There is. In other embodiments, the production site and the redundant site may each comprise a plurality of data centers, and each of the data centers may comprise a plurality of computing nodes and a plurality of storage nodes.

  The data center (101, 111) may further comprise a virtualization module (104, 114) and a cloud management module (105, 115), where the virtualization module (104, 114) is a physical server Configured to abstract computation (including processor and memory), storage, and network resources into multiple virtual machines, in effect each of the virtual machines has processor, memory, network connections, and storage, The operating system and applications may be executed, and the cloud management module (105, 115) may manage the virtualization module (104, 114) or each virtual machine, eg to create a virtual machine 104, 114).

  The storage nodes (102, 112) of the data center (101, 111) may be deployed separately, for example using a shared storage device. The storage node (102, 112) comprises a plurality of storage units and is configured to provide storage resources to each virtual machine, and provides shared partition access (read and write) function to the operating site / redundant site As a result, virtual machines of different computing nodes can simultaneously access the same partition of the same storage device. The storage nodes (102, 112) include storage management software (106, 116) that can manage the storage units of the storage nodes (102, 112). The shared storage device may be a network attached storage (NAS) device or a storage area network (SAN) device. For example, storage nodes (102, 112) may be SAN devices. The storage unit of the SAN device may in particular be a Logical Unit Number (LUN), where the LUN is a logical disk shown in the form of a storage array. Create a file system for each virtual machine on one or more LUNs of SAN devices. Storage management software of the SAN device may control reads and writes in the LUN and may manage the information of the LUN.

  In the embodiments of the present invention, when creating a cloud application to implement full redundancy of the cloud application, the cloud application template may be used directly to create the cloud application, or cloud management The module (105, 115) receives the cloud application template and instructs the virtualization module (104, 114) to create virtual machines and networks to be used by the cloud application according to the cloud application template May be Because cloud application templates can fully describe information such as virtual machines and networks that are required for cloud applications, deployment considerations when virtualization modules (104, 114) deploy virtual machines for cloud applications Can be done globally, thereby improving the efficiency of virtual machine deployment. Naturally, the cloud management module (105, 115) does not need to use the cloud application template when creating a virtual machine, instead using the virtual machine template in the prior art. Provide virtual machine templates as before to create.

  The cloud management module (105, 115) or virtualization module (104, 114) is deployed after the virtual machines and networks to be used by the cloud application are created by the virtualization module (104, 114) According to the virtual machine and the network of virtual machines, an instance running the cloud application, such as information about the cloud application, information on the virtual machine running the cloud application and information on the network used by the cloud application The description information of the cloud application may be generated, including the description information of Description information of the cloud application will be described in detail in the following embodiments. It is clear that the description information of the cloud application may include static description information of the cloud application as well as dynamic description information of the cloud application. Information communicated in the cloud application template or virtual machine template received by the cloud management module (105, 115) before the virtualization module (104, 114) deploys the virtual machine is a cloud such as the number or specifications of the virtual machine It may be referenced as static description information of the application, or after the virtualization module (104, 114) deploys a virtual machine, set the location or home network of the physical resource deployed to the virtual machine, Such information may be referred to as dynamic description information of the cloud application. After the virtualization module (104, 114) deploys the virtual machine, the cloud management module (105, 115) collects the dynamic description information and static description information of the cloud application, and describes the cloud application. Information may be generated. If the cloud management module (105, 115) uses the cloud application template to obtain static description information of the cloud application, then the cloud management module (105, 115) Only the dynamic description information of may be acquired. Cloud application description information may also be recorded in the form of a template in the cloud management module (105, 115). The cloud management module (105, 115) may record the cloud application description information using the new template or store all the cloud application description information by updating the cloud application template May be

  Additionally, in embodiments of the present invention, cloud management interfaces (107, 117) may be added to the cloud management module (105, 115) to implement redundancy based on cloud applications, which is The cloud management module (105, 115) supports querying for cloud application description information of the cloud application currently being executed on the operation site, and for the cloud application according to the cloud application description information acquired by the query It means to perform redundant operation.

Setting Process in Specific Embodiment 1 As shown in FIG. 5 with reference to the system mechanism shown in FIG. 1 (a), the redundancy required in the redundant site is required according to the setting information when the redundant incident occurs at the operating site. In order to recover a clustered cloud application, the redundancy method provided by the embodiments of the present invention is used to set up a redundant site cloud application on a production site at a redundant site. The method may be performed by a redundancy management module. The method may include the following.

  501: From the cloud management module at the operation site to the first description information of the cloud application requiring redundancy, which is related to the source network used at the operation site by the cloud application requiring redundancy and by the cloud application requiring redundancy First description information is obtained, including information about source virtual machines being used at the production site.

  The information on the source virtual machine includes an identifier and specification of the source virtual machine, information on the first storage unit occupied by the source virtual machine at the production site, and information on the home network of the source virtual machine.

  Furthermore, the information on the home network of the backup virtual machine includes the network address of the source virtual machine or the association between the virtual network adapter of the source virtual machine and the source network.

  For example, in the system scheme shown in FIG. 1 (a), three cloud applications, including APP1, APP2 and APP3, are operating at the production site. The cloud management module at the operation site may store the topology relationship of each cloud application, where the topology relationship of the cloud application may be expressed using the first description information of the cloud application . As an example, first description information of the cloud application APP1 is shown in FIG.

  If it is determined that APP1 is a redundant cloud application, the cloud management module or the redundant management module at the operation site may acquire the first description information of APP1. The first description information of APP1 may be as shown in Table 1, including the following.

1) Information on the source network used by the APP1 at the production site Information on the source network can be information on the subnet in which the source virtual machine running the cloud application exists (Subnet) or a virtual application running the cloud application It may be information on a virtual local area network (VLAN) in which a machine exists, or both. For example,
APP1 uses Network1 and Network2.
Network 1 (Subnet address: 10.100.35.0/24, VLAN ID = 35)
Network 2 (Subnet address: 10.100.36.0/24, VLAN ID = 36)

2) Identifier and Specification of Source Virtual Machine Used at Production Site by APP1 The identifier of the source virtual machine is allocated by the production site, and may be a Universally Unique Identifier (uuid) or a source virtual machine. The machine specification contains information about processor and memory. For example, when the operating site uses the source virtual machines VM1, VM2, and VM3 to execute the cloud application APP1, the identifiers and specifications of the source virtual machines used by the APP1 at the operating site are as follows: As it is.
VM1 (uuid = 1, 2V CPU, 60G memory)
VM2 (uuid = 2, 2V CPU, 60G memory)
VM3 (uuid = 3, 2V CPU, 40G memory)

3) Information on the first storage unit occupied at the production site by the source virtual machine used by APP1 Information on the first storage unit occupied at the production site by the source virtual machine is a single virtual It may be information on the storage unit of the machine. For example, the information on the first storage unit occupied by the source virtual machine being used by APP1 is VM1-> LUN1 and LUN2, VM2-> LUN1, and VM3-> LUN2 and LUN3, or redundant required It may be all the information on the first storage unit being used at the operation site by the virtualization cloud application. For example, the information on the first storage unit occupied by the source virtual machine being used by APP1 is LUN1, LUN2 and LUN3, which in this case is occupied at the production site by the source virtual machine The information regarding the first storage unit may not include the association between the source virtual machine and the storage unit occupied by the source virtual machine. The identifier of the source virtual machine is stored in the storage unit occupied by the source virtual machine, so the cloud management module or redundant site at the production site follows the identifier of the source virtual machine and which disk file of which LUN is the source It may be determined whether it is being used by a virtual machine, ie determining the association between the source virtual machine being used at the production site by the redundant cloud application and the storage unit occupied by the source virtual machine You may

4) Network address of the source virtual machine used on the operation site by APP1 The network address of the source virtual machine used on the operation site by the redundant cloud application is especially the IP address of the virtual network adapter of the source virtual machine It may be. For example, the network address of the source virtual machine being used by APP1 is
VM1-VNIC1-> IP address: 10.100.35.10/24,
VM2-VNIC2-> IP address: 10.100.35.11/24,
VM3-VNIC3-> IP address: 10.100.35.12/24,
VM3-VNIC3 '-> IP address: 10.100.36.12/24.

5) Association between the virtual network adapter and source network of the source virtual machine used by APP1 For example, the association between the virtual network adapter and source network of the source virtual machine used by APP1 is VM1- VNIC1-> Network1 connected, VM2-VNIC2-> Network2 connected, VM3-VNIC3-> Network1 connected, VM3-VNIC3 '-> Network2 connected.

  In the foregoing, 4) and 5) are two optional elements. The information regarding the home network of the source virtual machine of APP1 may include any one of 4) or 5), or may include both 4) and 5).

  In particular, there may be two ways to implement step 501 of obtaining the first description information of the cloud application requiring redundancy from the cloud management module at the operation site.

1) First method The redundancy management module uses the interface connected to the cloud management module at the operation site to obtain the first description information of the cloud application requiring redundancy from the cloud management module at the operation site In this case, the cloud management module at the production site collects static description information and dynamic description information of the running instance of the cloud application after the cloud application virtual machine is deployed. One piece of description information may be generated.

2) Second method The redundant management module is used on the operating site by the cloud application requiring redundancy from the cloud management module on the operating site using the interface connected to the cloud management module on the operating site. The first description information is generated by inquiring about the identifier and specification of the source virtual machine, the information on the first storage unit occupied at the operation site by the source virtual machine, and the network address of the source virtual machine.

  In particular, the step of generating the first description information includes the step of determining information on the source network used at the operation site by the cloud application requiring redundancy according to the network address of the source virtual machine, and the source virtual machine home Determining information about the network, information about the source network, identifiers and specifications of the source virtual machine, information about the first storage unit occupied at the production site by the source virtual machine, and information about the home network of the source virtual machine And acquiring the first description information according to. For example, when the IP address of the virtual network adapter of the source virtual machine VM1 is 10.100.35.10/24, it can be acquired that the mask of the IP address is 255.255.255.0, and the AND operation is performed on the IP address and the mask And between the APP1 gets the Subnet address used at the working site is 10.100.35.0/24, as well as the Subnet address used by the APP1 at the working site is the virtual network adapter of VM2 To be 10.100.35.0/24 and 10.100.36.0/24 based on the IP address of and the IP address of the virtual network adapter of VM3 separately, thus regarding the source network being used at the production site by APP1 By obtaining that the information is Network 1 (Subnet address: 10.100.35.0/24) and Network 2 (Subnet address: 10.100.36.0/24) Can. Finally, generated information on the source network used at the operation site by the redundant cloud application, an identifier and specification of the source virtual machine, information on the first storage unit occupied at the operation site by the source virtual machine, And according to the source virtual machine's network address, generate the first description information of APP 1 as shown in Table 1.

  Furthermore, if the information about the source virtual machine home network includes an association between the source virtual machine virtual network adapter and the source network, then the association between the source virtual machine virtual network adapter and the source network is the source network It may be determined according to the information on and the network address of the source virtual machine. For example, if the information on the source network of APP1 is Network1 (Subnet address: 10.100.35.0/24, VLAN ID = 35), and Network2 (Subnet address: 10.100.36.0/24, VLAN ID = 36), then APP1 According to the network address VM1-VNIC1-> IP address of the source virtual machine being used by: 10.100.35.10/24, determine that the IP address of the virtual network adapter of the source virtual machine belongs to the network segment 10.100.35.0/24 And can further determine that VM1-VNIC1 is associated with Network1, similarly, VM2-VNIC2 is associated with Network1, VM3-VNIC3 is associated with Network1, and VM3-VNIC3 is It can be determined that it is associated with Network2, i.e. the relationship between the virtual network adapter of the source virtual machine of APP1 and the source network is obtained.

  502: Determine the identifier and specification of the backup virtual machine being used at the redundant site by the redundant cloud application according to the information on the source virtual machine.

  After obtaining the first description information, the redundancy management module performs backup virtual use at the redundant site by the redundancy required cloud application according to the identifier and specification of the source virtual machine conveyed in the information on the source virtual machine Machine identifiers and specifications may be determined. In particular, when recovering a redundant cloud application to a redundant site, it is necessary to create a backup virtual machine corresponding to the source virtual machine being used at the operating site by the redundant cloud application. . The specification of the backup virtual machine used at the redundant site by the redundant cloud application is identical to the specification of the source virtual machine. Thus, the virtual machine identifier may be set for the backup virtual machine according to the identifier of the source virtual machine, or the specification of the backup virtual machine may be determined according to the specification of the source virtual machine, where: The identifier may be the same as or different from the identifier of the source virtual machine.

  For example, the identifiers and specifications of the three source virtual machines being used by APP1 are VM1 (uuid = 1; 2VCPU, 60G memory), VM2 (uuid = 1; 2VCPU, 60G memory), and VM3 (uuid = 1; 2V CPU, 40G memory). Three virtual machines may be set to correspond to three source virtual machines as backup virtual machines used at redundant sites by redundant cloud applications, ie, backup virtual machine VM11 '(uuid = 11) is set to correspond to VM1 (uuid = 1), and the backup virtual machine VM12 ′ (uuid = 12) is set to correspond to VM2 (uuid = 2), The machine VM13 ′ (uuid = 13) is set to correspond to VM3 (uuid = 3). As shown in Table 1, the specifications of VM11 '(uuid = 11), VM12' (uuid = 12), and VM13 '(uuid = 13) are VM1 (uuid = 1), VM2 (uuid = 2), When it is determined that the specifications of the backup virtual machine and the VM3 (uuid = 3) respectively match, the identifier and the specification of the backup virtual machine are VM11 '(uuid = 11, 2VCPU, 60G memory), VM12' (uuid = 12, 2VCPU, 60G Memory) and VM 13 '(uuid = 13, 2 V CPU, 40 G memory) are determined.

  503: Determine, according to the information on the source virtual machine, the information on the second storage unit occupied by the backup virtual machine at the redundant site.

  After obtaining the first description information, the redundancy management module may determine the information on the second storage unit according to the information on the first storage unit conveyed in the information on the source virtual machine. In particular, the following three steps may be included.

  503a: Get idle storage units of redundant site.

  Storage management software at a redundant site may manage storage nodes at the redundant site, and can collect statistics of resource occupancy of all storage units of the storage node. Thus, the redundancy management module may obtain information about idle storage units by querying storage management software at the redundant site. For example, when storage management software of a redundant site collects statistics of LUN resource occupancy of a SAN device of a redundant site that LUN 1 'to LUN 6' are occupied and LUN 7 'to LUN 15' are not occupied. The idle storage units to be acquired are LUN 7 'to LUN 15'.

  503b: Select the second storage unit from the idle storage units of the redundant site.

  The redundancy management module may select a storage unit from an idle storage unit at a redundant site as a second storage unit according to the information on the first storage unit. For example, the first storage unit occupied by the source virtual machine being used by APP1 is LUN1, LUN2 and LUN3 and the three storage units are idle storage units LUN7 'to LUN15' second storage unit And the second storage unit includes LUN 7 ', LUN 8', and LUN 9 '.

  503c: Create a replication relationship between the first storage unit and the second storage unit to determine information about the second storage unit occupied at the redundant site by the backup virtual machine.

After determining the second storage unit, the redundancy management module further determines the replication relationship between the first storage unit and the second storage unit, and according to the replication relationship, at the redundant site by the backup virtual machine Information regarding the second storage unit being occupied may be determined. In particular, after determining the identifiers and specifications of the backup virtual machines being used at the redundant site by the cloud application requiring redundancy, the redundancy management module further adds the correspondence between the source virtual machine identifier and the backup virtual machine identifier. Create and associate the source virtual machine identifier with the backup virtual machine identifier, information about the first storage unit occupied at the operation site by the source virtual machine, and the first storage unit and the second storage Information about the second storage unit occupied at the redundant site may be determined by the backup virtual machine according to the replication relationship with the unit. For example, the first storage units occupied at the production site by the source virtual machine being used by APP1 are VM1-> LUN1 and LUN2, VM2-> LUN1, and VM3-> LUN2 and LUN3, by APP1 The second storage unit occupied at the redundant site by the backup virtual machine being used is LUN 7 ', LUN 8', and LUN 9 ', and the user is VM1 (uuid = 1)->VM11' (uuid = 11) According to VM2 (uuid = 2)-> VM12 '(uuid = 12), and VM3 (uuid = 3)-> VM 13' (uuid = 13) and (LUN1, LUN2, and LUN3) and (LUN 7 ', LUN 8' , And LUN 9 ') can be directly specified as LUN1->LUN7',LUN2-> LUN8 ', and LUN3->LUN9', and so on, in the redundant site by the backup virtual machine. If the information related to the second storage unit in question is VM11 '(uuid = 11)->LUN7' and LUN8 ', VM12' (uuid = 12)-> LUN7 ', It can be determined that VM 13 '(uuid = 13)-> LUN 8' and LUN 9 ', and even if the replication relationship between the first storage unit and the second storage unit is determined according to the user's designation. Good.

  The information on the second storage unit occupied at the redundant site by the backup virtual machine is the information on the storage unit of a single virtual machine, eg VM11 '(uuid = 11)-> LUN7' and LUN8 ', VM12' (uuid = 12)-> LUN 7 'and VM 13' (uuid = 13)-> LUN 8 'and LUN 9'. Alternatively, the information on the second storage unit occupied at the redundant site by the backup virtual machine may be all information on the second storage unit being used at the redundant site by the redundant cloud application, eg, LUN 7 ', LUN 8 'And LUN 9', in which case information about the first storage unit occupied at the production site by the backup virtual machine is the backup virtual machine and the storage unit occupied by the backup virtual machine The source virtual machine identifier is stored in the second storage unit and may not include an association between the backup virtual machine and the storage unit occupied by the backup virtual machine. The association may be determined according to the source virtual machine identifier and the backup virtual machine identifier.

  504: Instruct storage management software of the active site and storage management software of the redundant site to replicate data of the first storage unit to the second storage unit.

  After step 503, the redundancy management module sets the replication relationship between the first storage unit and the second storage unit in the storage management software of the operating site and the storage management software of the redundant site, so that the operation is performed. The storage management software of the site and the storage management software of the redundant site, the first storage in the second storage unit according to the replication relationship between the first storage unit and the second storage unit and the defined replication cycle and mode Unit data can be replicated.

  For example, the first storage units occupied at the production site by the source virtual machine being used by APP1 are LUN1, LUN2 and LUN3, which are occupied by the backup virtual machine being used by APP1 at the redundant site The second storage units are LUN7 ', LUN8', and LUN9 ', and the replication relationship between (LUN1, LUN2, and LUN3) and (LUN7', LUN8 ', and LUN9') is LUN1-. If it is determined that> LUN 7 ', LUN 2-> LUN 8', and LUN 3-> LUN 9 ', the replication relationship is set in the storage management software of the operating site and the redundant site, as a result, the storage management of the operating site The software and redundant sites replicate the data of LUN1, LUN2 and LUN3 to LUN7 ', LUN8' and LUN9 'respectively in preset form, for example every 5 minutes and in incremental form.

  505: Configure information about the backup network for the cloud application requiring redundancy according to the information about the source network.

After obtaining the first description information, the redundancy management module may configure the information on the backup network for the redundancy required cloud application according to the information on the source network conveyed in the first description information . In particular, information about the source network is a subnet (Subnet) in which a source virtual machine that is running a redundant cloud application is present, or a virtual local in which a source virtual machine that is running a redundant cloud application is present Since the information on the area network (virtual local area network, VLAN), or both may be information, the step of configuring the information on the backup network for the cloud application requiring redundancy according to the information on the source network may include the subnet of the source network According to the information, allocating Subnet address to unused Subnet address of redundant site and using it as subnet information of backup network,
And allocating the VLAN ID to the unused VLAN ID of the redundant site according to the VLAN information of the source network and using it as VLAN information of the backup network.

  In this case, the information on the backup network may be subnet information of the backup network, or VLAN information of the backup network, or both of them.

  The unused Subnet address and VLAN ID of the redundant site may be stored in advance, may be obtained from the user, or may be determined according to a rule. In the process of setting up the backup network of APP1, the Subnet address and / or VLAN ID may be selected from unused Subnet addresses and / or VLAN IDs of redundant sites and may serve as information on the backup network.

  For example, the information on the source network used by APP1 is Network 1 (Subnet address: 10.100.35.0/24, VLAN ID = 35), Network2 (Subnet address: 10.100.36.0/24, VLAN ID = 36), The two Subnet addresses and the two VLAN IDs in the unused network at the redundant site may be designated as information on the backup network of APP1 according to the user instruction. In particular, the corresponding backup Subnet addresses specified for the Subnet addresses of Network1 and Network2 are 10.100.35.0/24->20.200.135.0/24 and 10.100.36.0/24->20.200.136.0/24 and If the corresponding backup VLAN IDs specified for the VLAN IDs of Network1 and Network2 are VLAN ID = 35-> 135 and VLAN ID = 36-> 136, then the information about the backup network of APP1 is , Network 1 '(Subnet address: 20.200.135.0/24, VLAN ID = 135), and network 2' (Subnet address: 20.200.136.0/24, VLAN ID = 136).

  In addition, unused Subnet addresses and VLAN IDs of redundant sites may include Subnet addresses and VLAN IDs that match Subnet addresses and VLAN IDs of the source network. Thus, the information on the backup network may be specified to be identical to the information on the source network, so that the network address of the source virtual machine may be identical to the network address of the backup virtual machine. That is, the cloud application requiring redundancy can use the same network address at the operation site for service processing and at the redundant site. For example, if the unused subnet addresses of the redundant site include 10.100.35.0/24 and 10.100.36.0/24, and the unused VLAN IDs of the redundant site include VLAN ID = 35 and VLAN ID = 36. The information about the backup network may be set as network 1 '(Subnet address: 10.100.135.0/24, VLAN ID = 35), network2' (Subnet address: 10.100.136.0/24, VLAN ID = 36), etc. As a result, the information on the backup networks network1 'and network2' will be identical to the information on the source networks Network1 and Network2 and thus, during the period of redundancy, the network addresses identical to those of the source virtual machine will be backup virtual It may be allocated to a machine.

  506: Determine the information on the backup virtual machine home network according to the information on the source virtual machine and the information on the backup network.

  After obtaining the first description information, the redundancy management module further obtains information on the home network of the source virtual machine, an identifier of the backup virtual machine, and information on the backup network, and relates to the home network of the source virtual machine. The information on the backup virtual machine home network may be determined according to the information, the backup virtual machine identifier, and the information on the backup network, where the information on the backup virtual machine home network is the backup virtual machine network address, or An association between the virtual network adapter of the backup virtual machine and the backup network may be included.

Information on the source virtual machine's home network includes the source virtual machine's network address or the association between the source virtual machine's virtual network adapter and the source network, so information on the source virtual machine's home network, backup virtual machine Determining the information on the backup virtual machine home network according to the information on the identifier of the backup virtual network and the information on the backup network: Determining an association between a virtual network adapter of the source virtual machine and the source network, the source virtual machine Determining the network address of the backup virtual machine according to the association between the virtual network adapter and the source network, the identifier of the backup virtual machine and the information on the backup network, so that after redundancy The redundant cloud application can use the specified backup virtual machine's network address, where between the source virtual machine's virtual network adapter and the source network according to the source virtual machine's network address and information about the source network For specific implementation of the step of determining the association of
(2) obtaining an association between the virtual network adapter of the source virtual machine and the source network, which is conveyed in information about the home network of the source virtual machine, and between the virtual network adapter of the source virtual machine and the source network Determining the network address of the backup virtual machine according to the association of the backup virtual machine, the identifier of the backup virtual machine, and the information on the backup network, or

Furthermore, after configuring the information on the backup network for the cloud application requiring redundancy, the redundancy management module further creates a correspondence between the information on the source network and the information on the backup network, and the redundancy application on the network requires redundancy. After determining the identifier and specification of the backup virtual machine being used at the redundant site according to, further create a correspondence between the identifier of the source virtual machine and the identifier of the backup virtual machine. Therefore, the step of determining the network address of the backup virtual machine according to the association between the virtual network adapter of the source virtual machine and the source network, the identifier of the backup virtual machine, and the information on the backup network specifically refers to the network address of the backup virtual machine The association between the information on the source network and the information on the backup network, the association between the identifier of the source virtual machine and the identifier of the backup virtual machine, and the virtual network adapter of the source virtual machine and the source network It may be determined according to the association. For example, the network address of the source virtual machine used by APP1 at the operation site is VM1-VNIC1-> IP address: 10.100.35.10/24, VM2-VNIC2-> IP address: 10.100.35.1/24, VM3-VNIC3 -> IP address: 10.100.35.12/24, and VM3-VNIC3 '-> IP address: 10.100.36.12/24, and information about the backup network configured for APP1 can be network 1' (Subnet address: 20.200. 135.0 / 24), and network 2 '(Subnet address: 20.200.136.0/24). VM3-VNIC3 '-> IP address: 10.100.36.12/24 belongs to Network2 (Subnet address: 10.100.36.0/24), so backup network network2' corresponding to Network2 (Subnet address: 20.200.136.0/24) One IP address in) is designated as the network address of the backup virtual machine VM13 '.

For example, the information about the second storage unit occupied by the backup virtual machine being used at the redundant site by APP1 is VM11 '-> LUN7' and LUN8 ', VM12'-> LUN7 ', and VM13'->. Assuming LUNs 8 'and 9', the cloud management module at the redundant site may determine the compute nodes associated with LUN 7 ', LUN 8', and LUN 9 ', and the computing node's resources Instruct the virtualization modules at the redundant site to use the virtual network adapter VM11 '(uuid = 11; 2VCPU, 60G memory, VNIC11) for backup virtual machines and backup virtual machines, VM12' (uuid = 12; 2VCPU , 60G memory, VNIC 12), and VM 13 '(uuid = 13; 2VCPU, 40G memory, VNIC 13 and VNIC 13') according to the information on the second storage unit , Specify that VM 11 'occupies storage unit LUN 7' and LUN 8 ', VM 12' occupies storage unit LUN 7 'and VM 13' occupies storage unit LUN 8 'and LUN 9', where computing The backup virtual machine VM11 'created in the node can access the storage units LUN 7' and LUN 8 ', the VM 12' can access the storage unit LUN 7 ', and the VM 13' can access the storage units LUN 8 'and LUN 9'. The computing node may be one or more, as long as it guarantees that it can be accessed, and is not limited in the embodiment of the present invention.

  In addition, the virtualization module at the redundant site may further allocate a Media Access Control (MAC) address to the virtual network adapter of the created backup virtual machine.

  705: Allocate a network address to the backup virtual machine according to the second description information.

  After the backup virtual machine is created, the cloud management module at the redundant site allocates the network address to the virtual network adapter of the created backup virtual machine, and the dynamic host configuration of the virtualization module or redundant site at the redundant site A protocol (Dynamic Host Configuration Protocol, DHCP) server may be instructed, where the network address may be an IP address. In particular, redundant sites may allocate network addresses to virtual network adapters of backup virtual machines using the following two methods.

1) First method The cloud management module at the redundant site determines the network address of the backup virtual machine, and instructs the virtualization module at the redundant site to create a virtual network adapter for the backup virtual machine. Then, assign the backup virtual machine's network address to the backup virtual machine's virtual network adapter. In particular, if the network address is set for the backup virtual machine used by the cloud application requiring redundancy in the redundancy setting process, the information on the home network of the backup virtual machine is the network of the backup virtual machine. The address may be communicated, and the cloud management module at the redundant site may obtain the network address of the backup virtual machine communicated in the information on the home network of the backup virtual machine. In the redundancy setting process, if the network address is not set for the backup virtual machine used by the redundant cloud application, the cloud management module in the redundant site is the backup network corresponding to the backup virtual machine. The network address may be allocated to the virtual network adapter of the backup virtual machine according to the information on the backup network and the association between the virtual network adapter of the backup virtual machine and the backup network from the unused network address of

  In particular, if the network address is set for the backup virtual machine used by the cloud application requiring redundancy in the redundancy setting process, the information on the home network of the backup virtual machine is the network of the backup virtual machine. The address is transmitted, and the cloud management module at the redundant site obtains the physical address of the virtual network adapter of the backup virtual machine, and between the network address of the backup virtual machine and the physical address of the virtual network adapter of the backup virtual machine Network address of the backup virtual machine, physical address of the virtual network adapter of the backup virtual machine, on the redundant site DHCP server, creating an association And may register an association between the backup virtual machine's network address and the backup virtual machine's virtual network adapter's physical address, so that the DHCP server at the redundant site will backup virtual to the backup virtual machine's virtual network adapter Allocate a machine's network address. For example, the cloud management module at the redundant site obtains the MAC addresses of the VM 11 ′, VM 12 ′, and VM 13 ′ from the virtualization modules at the redundant site, and obtains VM 11 ′, VM 12 ′, and VM 12 ′ from the second description information. Acquire the IP address set in advance of VM 13 ', create the correspondence between the MAC address and IP address of VM 11', VM 12 ', and VM 13' separately, and register the correspondence with the DHCP server As a result, the DHCP server can allocate the VM 11 ′, the VM 12 ′, and the VM 13 ′ to preset IP addresses. In the redundancy setting process, if the network address is not set for the backup virtual machine used by the cloud application requiring redundancy, the cloud management module at the redundant site is configured to receive information on the backup network and the backup virtual machine. According to the association between the virtual network adapter and the backup network, determine the information about the backup network that is associated to correspond to the backup virtual machine, and to correspond to the backup virtual machine to the DHCP server of the redundant site Register information about the associated backup network, so that DHCP servers at redundant sites are associated to correspond to backup virtual machines. Allocating a network address to the virtual network adapter of the backup virtual machine in accordance with the information about the backup network. For example, the cloud management module at the redundant site shown in FIG. 1 (a), or FIG. 1 (b), or FIG. 1 (c) has a subnet address of 20.200 for the network associated to correspond to VM 11 '. .135.0 / 24, the subnet address of the network associated to correspond to VM 12 'is 20.200.135.0/24, and the subnet address of the network associated to correspond to VM 13' is 20.200.135.0 Decide / 24 and 20.200.136.0/24 to register with the DHCP server the Subnet address of the network associated to correspond to the backup virtual machine, so that the DHCP server corresponds to VM 11 ' Assign a dynamic IP address to VM 11 'according to the subnet address of the associated network, and according to the subnet address of the network associated to correspond to VM 12' The dynamic IP address is allocated to the VM 12 ', and the dynamic IP address is allocated to the VM 13' according to the subnet address of the network associated with the VM 13 '.

  706: Instruct the virtualization module at the redundant site to associate the backup network with the backup virtual machine according to the information on the backup virtual machine in the second description information.

In particular, where the cloud management module at the redundant site can obtain the association between the backup virtual machine virtual network adapter and the backup network according to the information on the backup virtual machine home network, where the backup virtual machine virtual network The step of obtaining the association between the adapter and the backup network is directly obtained from the information on the backup virtual machine home network, or the network of the backup virtual machine in the information on the backup virtual machine home network and the information on the backup network Association between backup virtual machine virtual network adapter and backup network according to address It may be a step of determining.

  The cloud management module at the redundant site obtains the correspondence between the information on the backup network and the port group of the virtual switch from the virtualization module at the redundant site, and the virtual network adapter of the backup virtual machine and the backup network The association between the virtual network adapter of the backup virtual machine and the port group of the virtual switch may be determined according to the association between the above and the association between the information on the backup network and the port group of the virtual switch.
