The invention provides an application disaster recovery device. As shown in fig. 1, fig. 1 is a schematic composition diagram of a functional module of the application disaster recovery device. Wherein the apparatus comprises:
a tunnel creation module 10, configured to create virtual network tunnels between the private cloud and each alternative cloud environment according to user configuration;
in one embodiment, as shown in fig. 2, the tunnel creating module 10 includes an obtaining unit 110, configured to obtain a setting value of the number of virtual network tunnels set by a user and/or priority setting information of each cloud environment, and/or read preset state information of each cloud environment to determine priority information of each cloud environment;
the user side is used for realizing the setting operation of the user, and can be a web page side or an application program running on a mobile terminal (such as a mobile phone and a tablet computer). When a virtual network tunnel between the private cloud and each alternative cloud environment needs to be created, a user sets the virtual network tunnel through the user side, so that the user side triggers a tunnel creation request to the tunnel creation module 10.
Specifically, a user sets the number of virtual network tunnels between a private cloud and each alternative cloud environment, which need to be created by the application disaster recovery device, through a user side; optionally, the priority of a certain cloud environment may also be set by the user side. The obtaining unit 110 is responsible for interacting with the ue to obtain the set value of the number of virtual network tunnels set on the ue and/or the priority setting information of each cloud environment.
Generally, the number of virtual network tunnels is set to be greater than 1 to provide alternative virtual network tunnels and cloud environments, for example, to be 2. All the default priorities of the cloud environments are at the same level, and a user can set or divide the priority level of a certain cloud environment according to needs (or not set the priority level); the cloud environment with the high priority is preferentially selected as the cloud environment for application deployment.
It should be noted that the type of the "cloud environment" referred to in the embodiments of the present invention is not necessarily limited, and any "cloud environment" may be a public cloud environment or a private cloud environment, or other types of cloud environments.
When receiving the tunnel creation request, the obtaining unit 110 optionally reads preset state information of each cloud environment to determine priority information of each cloud environment. Specifically, the application disaster recovery device further includes a cloud environment resource pool (not shown in fig. 1). The cloud environment resource pool monitors each cloud environment based on a specific API (application programming interface), and acquires a cloud environment list, wherein the list comprises preset characteristic information of each cloud environment. The cloud environment resource pool reports the preset feature information of each cloud environment to the obtaining unit 110.
The preset feature information of any cloud environment is used for representing a corresponding cloud environment state, and specifically may include but is not limited to: the cloud environment has an occupancy level for computing resources, network resources, and storage resources. And determining the priority information (priority level) of each cloud environment according to the preset characteristic information of each cloud environment. For example, if the occupancy rate level of a certain cloud environment to computing resources, network resources, and storage resources is low, the priority level of the cloud environment is high, and the cloud environment should be preferentially determined as the candidate cloud environment. That is, under the same condition, the lower the resource occupancy rate of a certain cloud environment is, the higher the priority level of the cloud environment is.
A first determining unit 120, configured to determine, according to the set value of the number of virtual network tunnels and/or the priority setting information of each cloud environment, and/or the priority information of each cloud environment, a specified number of cloud environments from each cloud environment as alternative cloud environments; the specified number is equal to the virtual network tunnel number set value, and the rest undetermined cloud environments are used as idle cloud environments;
performing comprehensive sequencing on the cloud environments according to the priority information of the cloud environments and/or the priority information of the cloud environments; and according to the comprehensive sequencing result, determining the specified number of cloud environments as alternative cloud environments, and using the rest undetermined cloud environments as idle cloud environments, wherein the specified number is equal to the virtual network tunnel number set value.
In a preferred embodiment, the cloud environments are sorted according to the set priority level according to the priority setting information of the cloud environments set by the user terminal. Assuming that the client sets A, B, C, D, E the priority information of five cloud environments as 3, 1, 2, and 3 (the priority is higher, the priority is selected preferentially), the reverse ordering result of the priority of the five cloud environments is: a ═ E > D > B ═ C. If the set value of the number of virtual network tunnels is 2, 2 cloud environments (i.e., a and E) with higher priority levels are determined as alternative cloud environments, and the remaining 3 cloud environments (i.e., B, C, D) are idle cloud environments. If the number of virtual network tunnels is set to be 3, 3 cloud environments (i.e., A, E and D) with higher priority levels are determined to be alternative cloud environments, and the remaining 2 cloud environments (i.e., B, C) are idle cloud environments. If the alternative cloud environment needs to be determined in a plurality of cloud environments with the same priority level, the alternative cloud environment can be randomly selected. The rest can be analogized in the same way.
In another preferred embodiment, the cloud environments are sorted according to the set priority level according to the priority information of the cloud environments. And according to the sequencing result, determining the cloud environments with the specified number as alternative cloud environments, and taking the rest undetermined cloud environments as idle cloud environments. The specific determination process may refer to the above description, and is not described herein again.
The first tunnel creating unit 130 is configured to perform resource orchestration and deploy a gateway to each alternative cloud environment to create a virtual network tunnel from the private cloud to each alternative cloud environment.
And after determining the specified number of alternative cloud environments, establishing a virtual network tunnel from the private cloud to each alternative cloud environment.
The resource arrangement refers to arrangement and allocation of running environments or resources such as computing resources, network resources and storage resources. And after finishing the resource arrangement, deploying the gateway to each alternative cloud environment. The communication protocol used by the gateway can be selected from a general communication technology/protocol (such as a VXLAN gateway or an IPSec gateway is preferably used), or can be customized according to needs.
For example, the first tunnel creation unit 130 performs resource organization, and automatically deploys a VXLAN gateway or an IPSec gateway locally and in each cloud environment. And establishing a network topology from the local to each cloud environment through a VXLAN gateway or an IPSec gateway, and realizing the intercommunication between the private cloud and the alternative cloud environment. In this way, the virtual network tunnel is realized by using VXLAN technology or IPSecVPN, so that two-layer network communication is realized between the private cloud and the alternative cloud environment.
Thereafter, the first tunnel creation unit 130 creates a virtual network tunnel from the private cloud to each alternative cloud environment. For example, alternative cloud environments have three in total: cloud environment A/B/C. And respectively deploying the gateways to the cloud environment A/B/C, and further respectively establishing a virtual network tunnel A/B/C from the private cloud to the alternative cloud environment A/B/C. Inter-cloud communication between the private cloud and different alternative cloud environments can be achieved based on the created virtual network tunnel.
In a specific implementation, as shown in fig. 3, the tunnel creation module 10 may further include:
a second determining unit 140, configured to determine a target alternative cloud environment from alternative cloud environments according to the priority setting information of each cloud environment and/or the priority information of each cloud environment, and determine a virtual network tunnel from a private cloud to the target alternative cloud environment as a target virtual network tunnel;
according to the priority level of each cloud environment, determining an alternative cloud environment with the highest priority level from the alternative cloud environments, taking the determined alternative cloud environment as a target alternative cloud environment, and further determining a virtual network tunnel from the private cloud to the target alternative cloud environment as a target virtual network tunnel. In this way, the candidate cloud environment with the highest priority and the least resource occupancy can be determined for the application deployment.
Understandably, the determination of the target candidate cloud environment and the target virtual network tunnel is performed after reading the preset state information of each cloud environment to determine the priority information of each cloud environment.
The application deployment module 20 is configured to deploy the application to the target alternative cloud environment through a target virtual network tunnel in the virtual network tunnels;
after a better alternative cloud environment is selected, the application is deployed to the target alternative cloud environment through the target virtual network tunnel, and therefore the application can normally run in the target alternative cloud environment. The implementation of a particular application deployment is not limited herein. In this way, by selecting a specified number of alternative cloud environments, respectively creating a virtual network tunnel from the private cloud to each alternative cloud environment, and deploying the application to one of the preferred alternative cloud environments, the dynamic disaster recovery infrastructure is pre-deployed.
And the application migration module 30 is configured to, when it is monitored that the target virtual network tunnel is abnormal, migrate the application to another alternative cloud environment through an alternative virtual network tunnel in the virtual network tunnels.
In specific implementation, the application migration module 30 is configured to migrate the application to the new target candidate cloud environment through the new target virtual network tunnel, as opposed to the execution step of the second determining unit 140.
Firstly, the application migration module 30 monitors the state information of the target virtual network tunnel in real time; and judging whether the target virtual network tunnel is interrupted or not according to the state information.
If the target virtual network tunnel is judged to be interrupted, acquiring and analyzing the state information to confirm whether the target virtual network tunnel is in a disconnection state or not so as to eliminate the recoverable condition of short-time disconnection of the target virtual network tunnel; or directly judging that the target virtual network tunnel is in a disconnection state when the state information cannot be acquired.
And when the target virtual network tunnel is confirmed to be in the disconnection state, carrying out application migration. Based on the second determination unit, another available alternative cloud environment is selected as a new target alternative cloud environment, and the virtual network tunnel between the private cloud and the new target alternative cloud environment is used as a new target virtual network tunnel. Further, the application is migrated to the new target candidate cloud environment through the new target virtual network tunnel, and for specific implementation, reference is made to the above, which is not described herein again. Because the virtual network tunnel between the private cloud and the new target alternative cloud environment is established in advance, the application can be rapidly migrated to other alternative cloud environments except the target alternative cloud environment through the virtual network tunnel with the new target alternative cloud environment, the efficiency of application conversion deployment is improved, and the effect of dynamic disaster tolerance is achieved.
The application disaster recovery device in this embodiment respectively creates a virtual network tunnel between the private cloud and each alternative cloud environment according to user configuration, and deploys the application to the target alternative cloud environment through a target virtual network tunnel in the virtual network tunnel, so that the application deployment cloud environment is optimized, and the disaster resistance of the application deployment cloud environment is improved.
In addition, based on the pre-deployment of the dynamic disaster recovery infrastructure, when a currently used target virtual network tunnel is disconnected, the currently applied deployment cloud environment is immediately switched to other normally available alternative cloud environments, so that a dynamic disaster recovery effect with high reliability is achieved. For a user, the cloud environment abnormity does not need to be sensed, the manual intervention processing is also not needed, and the labor cost is saved to a certain extent. The intensity of the applied disaster tolerance characteristic is in direct proportion to the number of cloud environments, and the more alternative cloud environments are managed, the stronger the disaster tolerance characteristic is. In addition, the cloud environment can be prioritized according to user requirements, and flexible configuration is performed.
Further, based on the application disaster recovery apparatus in the first embodiment, as shown in fig. 4, the tunnel creation module 10 includes a third determining unit 150 and a second tunnel creation unit 160; wherein the content of the first and second substances,
the third determining unit 150 is configured to determine a new candidate cloud environment from the idle cloud environment according to the priority setting information of each cloud environment and/or the priority information of each cloud environment;
specifically, the third determining unit 150 sorts the cloud environments according to the set priority levels according to the priority setting information of the cloud environments and/or the priority information of the cloud environments. The third determining unit 150 determines, according to the sorting result, one idle cloud environment with the highest priority level from among the idle cloud environments as a new candidate cloud environment.
The second tunnel creating unit 160 is further configured to create a virtual network tunnel from the private cloud to the new alternative cloud environment after migrating the application to the other alternative cloud environment.
The creation of the virtual network tunnel from the private cloud to the new candidate cloud environment by the second tunnel creation unit 160 is the same as the creation of the virtual network tunnel described above, and is not described herein again. Alternatively, the second tunnel creation unit 160 may be identical to the first tunnel creation unit 130.
In this way, after the application migration module 30 switches the current application deployment cloud environment, the third determining unit 150 determines the new candidate cloud environment, and the second tunnel creating unit 160 creates virtual network tunnels from the private cloud to the new candidate cloud environment, so as to keep the total number of candidate cloud environments equal to the set virtual network tunnel number setting value. Therefore, the state that the number of alternative cloud environments is redundant is kept, the requirement of next disaster recovery switching is met, and the dynamic disaster recovery effect with high reliability is achieved.
Further, as shown in fig. 5, the application disaster recovery apparatus further includes a cloud environment resource pool 50; the cloud environment resource pool 50 is connected with the tunnel creation module 10; the cloud environment resource pool 50 is configured to manage the private cloud and each alternative cloud environment, and send a cloud environment list to the cloud environment resource pool 50 according to the data acquisition request of the tunnel creation module 10, where the list includes preset feature information of each cloud environment, which may be specifically referred to as a management index/content of a cloud environment managed by the cloud environment resource pool 50.
In this embodiment, the cloud environment resource pool 50 is responsible for managing all managed cloud environments, and management criteria/contents include but are not limited to: computing resources, network resources, storage resources, monitoring, and alarming. That is, the cloud environment resource pool 50 is a set of computing resources, storage resources, network resources, and the like that can be uniformly managed, allocated, and monitored, and can realize uniform management and allocation of the private cloud and each cloud environment.
In addition, the invention also provides an application disaster recovery method.
As shown in fig. 6, fig. 6 is a schematic flow chart of a disaster recovery method according to a first embodiment of the present invention. Wherein the method comprises the following steps:
step S10, respectively establishing virtual network tunnels between the private cloud and each alternative cloud environment according to user configuration;
in one implementation, as shown in fig. 7, step S10 includes: step S11, acquiring the virtual network tunnel number setting value set by the user end and/or the priority setting information of each cloud environment, and/or reading the preset state information of each cloud environment to determine the priority information of each cloud environment;
the user side is used for realizing the setting operation of the user, and can be a web page side or an application program running on a mobile terminal (such as a mobile phone and a tablet computer). When a virtual network tunnel between the private cloud and each alternative cloud environment needs to be created, the user performs setting through the user side, so that the user side triggers a tunnel creation request to the application disaster recovery device as described above.
Specifically, a user sets the number of virtual network tunnels between a private cloud and each alternative cloud environment, which need to be created by the application disaster recovery device, through a user side; optionally, the priority of a certain cloud environment may also be set by the user side. And the application disaster recovery device interacts with the user side to acquire the set value of the number of the virtual network tunnels set on the user side and/or the priority setting information of each cloud environment.
Generally, the number of virtual network tunnels is set to be greater than 1 to provide alternative virtual network tunnels and cloud environments, for example, to be 2. All the default priorities of the cloud environments are at the same level, and a user can set or divide the priority level of a certain cloud environment according to needs (or not set the priority level); the cloud environment with the high priority is preferentially selected as the cloud environment for application deployment.
It should be noted that the type of the "cloud environment" referred to in the embodiments of the present invention is not necessarily limited, and any "cloud environment" may be a public cloud environment or a private cloud environment, or other types of cloud environments.
When a tunnel creation request is received, optionally, preset feature information of each cloud environment is read. Specifically, each cloud environment is monitored based on a specific API (application programming interface), and a cloud environment list is obtained, where the list includes preset feature information of each cloud environment.
The preset feature information of any cloud environment is used for representing a corresponding cloud environment state, and specifically may include but is not limited to: the cloud environment has an occupancy level for computing resources, network resources, and storage resources. And determining the priority information (priority level) of each cloud environment according to the preset characteristic information of each cloud environment. For example, if the occupancy rate level of a certain cloud environment to computing resources, network resources, and storage resources is low, the priority level of the cloud environment is high, and the cloud environment should be preferentially determined as the candidate cloud environment. That is, under the same condition, the lower the resource occupancy rate of a certain cloud environment is, the higher the priority level of the cloud environment is.
Step S12, according to the virtual network tunnel number setting value and/or the priority setting information of each cloud environment, and/or the priority information of each cloud environment, determining a specified number of cloud environments from each cloud environment as alternative cloud environments; the specified number is equal to the virtual network tunnel number set value, and the rest undetermined cloud environments are used as idle cloud environments;
performing comprehensive sequencing on the cloud environments according to the priority information of the cloud environments and/or the priority information of the cloud environments; and according to the comprehensive sequencing result, determining the specified number of cloud environments as alternative cloud environments, and using the rest undetermined cloud environments as idle cloud environments, wherein the specified number is equal to the virtual network tunnel number set value.
In a preferred embodiment, the cloud environments are sorted according to the set priority level according to the priority setting information of the cloud environments set by the user terminal. Assuming that the client sets A, B, C, D, E the priority information of five cloud environments as 3, 1, 2, and 3 (the priority is higher, the priority is selected preferentially), the reverse ordering result of the priority of the five cloud environments is: a ═ E > D > B ═ C. If the set value of the number of virtual network tunnels is 2, 2 cloud environments (i.e., a and E) with higher priority levels are determined as alternative cloud environments, and the remaining 3 cloud environments (i.e., B, C, D) are idle cloud environments. If the number of virtual network tunnels is set to be 3, 3 cloud environments (i.e., A, E and D) with higher priority levels are determined to be alternative cloud environments, and the remaining 2 cloud environments (i.e., B, C) are idle cloud environments. If the alternative cloud environment needs to be determined in a plurality of cloud environments with the same priority level, the alternative cloud environment can be randomly selected. The rest can be analogized in the same way.
In another preferred embodiment, the cloud environments are sorted according to the set priority level according to the priority information of the cloud environments. And according to the sequencing result, determining the cloud environments with the specified number as alternative cloud environments, and taking the rest undetermined cloud environments as idle cloud environments. The specific determination process may refer to the above description, and is not described herein again.
And step S13, performing resource arrangement, and deploying the gateway to each alternative cloud environment to create a virtual network tunnel from the private cloud to each alternative cloud environment.
And after determining the specified number of alternative cloud environments, establishing a virtual network tunnel from the private cloud to each alternative cloud environment.
The resource arrangement refers to arrangement and allocation of running environments or resources such as computing resources, network resources and storage resources. And after finishing the resource arrangement, deploying the gateway to each alternative cloud environment. The communication protocol used by the gateway can be selected from a general communication technology/protocol (such as a VXLAN gateway or an IPSec gateway is preferably used), or can be customized according to needs.
For example, resource orchestration is performed first, and VXLAN gateways or IPSec gateways are automatically deployed locally and in various cloud environments. And establishing a network topology from the local to each cloud environment through a VXLAN gateway or an IPSec gateway, and realizing the intercommunication between the private cloud and the alternative cloud environment. In this way, the virtual network tunnel is realized by using VXLAN technology or IPSecVPN, so that two-layer network communication is realized between the private cloud and the alternative cloud environment.
Further, a virtual network tunnel of the private cloud to each alternative cloud environment is created. For example, alternative cloud environments have three in total: cloud environment A/B/C. And respectively deploying the gateways to the cloud environment A/B/C, and further respectively establishing a virtual network tunnel A/B/C from the private cloud to the alternative cloud environment A/B/C. And realizing inter-cloud communication between the private cloud and different alternative cloud environments based on the created virtual network tunnel.
In one implementation, as shown in fig. 8, step S10 further includes: step S14, determining a target alternative cloud environment from alternative cloud environments according to the priority setting information of each cloud environment and/or the priority information of each cloud environment, and determining a virtual network tunnel from a private cloud to the target alternative cloud environment as a target virtual network tunnel;
according to the priority level of each cloud environment, determining an alternative cloud environment with the highest priority level from the alternative cloud environments, taking the determined alternative cloud environment as a target alternative cloud environment, and further determining a virtual network tunnel from the private cloud to the target alternative cloud environment as a target virtual network tunnel. In this way, the candidate cloud environment with the highest priority and the least resource occupancy can be determined for the application deployment.
It is understood that step S14 may be executed after step S11, and the specific execution order of step S12 is not limited.
Step S20, deploying the application to a target alternative cloud environment through a target virtual network tunnel in the virtual network tunnels;
after a better alternative cloud environment is selected, the application is deployed to the target alternative cloud environment through the target virtual network tunnel, and therefore the application can normally run in the target alternative cloud environment. The implementation of a particular application deployment is not limited herein. In this way, by selecting a specified number of alternative cloud environments, respectively creating a virtual network tunnel from the private cloud to each alternative cloud environment, and deploying the application to one of the preferred alternative cloud environments, the dynamic disaster recovery infrastructure is pre-deployed.
Step S30, when the target virtual network tunnel is monitored to be abnormal, the application is migrated to other alternative cloud environments through the alternative virtual network tunnel in the virtual network tunnel.
In specific implementation, as opposed to step S14, the application is migrated to the new target candidate cloud environment through the new target virtual network tunnel.
Firstly, monitoring the state information of a target virtual network tunnel in real time; and judging whether the target virtual network tunnel is interrupted or not according to the state information.
If the target virtual network tunnel is judged to be interrupted, acquiring and analyzing the state information to confirm whether the target virtual network tunnel is in a disconnection state or not so as to eliminate the recoverable condition of short-time disconnection of the target virtual network tunnel; or directly judging that the target virtual network tunnel is in a disconnection state when the state information cannot be acquired.
And when the target virtual network tunnel is confirmed to be in the disconnection state, carrying out application migration. Namely, another available alternative cloud environment is selected as a new target alternative cloud environment, and the virtual network tunnel between the private cloud and the new target alternative cloud environment is used as a new target virtual network tunnel. Further, the application is migrated to the new target candidate cloud environment through the new target virtual network tunnel, and for specific implementation, reference is made to the above, which is not described herein again. Because the virtual network tunnel between the private cloud and the new target alternative cloud environment is established in advance, the application can be rapidly migrated to other alternative cloud environments except the target alternative cloud environment through the virtual network tunnel with the new target alternative cloud environment, the efficiency of application conversion deployment is improved, and the effect of dynamic disaster tolerance is achieved.
In this embodiment, virtual network tunnels between the private cloud and the alternative cloud environments are respectively created according to user configuration, and the application is deployed to the target alternative cloud environment through a target virtual network tunnel in the virtual network tunnels, so that the application deployment cloud environment is optimized, and the disaster resistance of the application deployment cloud environment is improved.
In addition, based on the pre-deployment of the dynamic disaster recovery infrastructure, when a currently used target virtual network tunnel is disconnected, the currently applied deployment cloud environment is immediately switched to other normally available alternative cloud environments, so that a dynamic disaster recovery effect with high reliability is achieved. For a user, the cloud environment abnormity does not need to be sensed, the manual intervention processing is also not needed, and the labor cost is saved to a certain extent. The intensity of the applied disaster tolerance characteristic is in direct proportion to the number of cloud environments, and the more alternative cloud environments are managed, the stronger the disaster tolerance characteristic is. In addition, the cloud environment can be prioritized according to user requirements, and flexible configuration is performed.
Further, based on the first embodiment of the application disaster recovery method of the present invention, a second embodiment of the application disaster recovery method of the present invention is provided. As shown in fig. 9, after step S30, the method further includes:
step S40, determining a new alternative cloud environment from the idle cloud environment according to the priority setting information of each cloud environment and/or the priority information of each cloud environment;
specifically, the cloud environments are sorted according to the set priority levels according to the priority setting information of the cloud environments and/or the priority information of the cloud environments. And according to the sequencing result, determining one idle cloud environment with the highest priority level from all idle cloud environments as a new alternative cloud environment.
Step S41, create a virtual network tunnel from the private cloud to the new alternate cloud environment.
Fig. 10 shows a specific implementation flowchart of the disaster recovery method according to the present invention, and the creation of the virtual network tunnel from the private cloud to the new candidate cloud environment is the same as the creation of the virtual network tunnel described above, and is not described here again.
In this way, after the switching of the current application deployment cloud environment is performed, the determination of the new alternative cloud environment is performed, and the virtual network tunnels from the private cloud to the new alternative cloud environment are created, so as to keep the total number of the alternative cloud environments equal to the set virtual network tunnel number setting value. Therefore, the state that the number of alternative cloud environments is redundant is kept, the requirement of next disaster recovery switching is met, and the dynamic disaster recovery effect with high reliability is achieved.
