As used in this application and the claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein is meant to encompass any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present application to describe various information, the information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. Depending on the context, moreover, the word "if" as used may be interpreted as "at … …" or "when … …" or "in response to a determination".
Exemplarily, referring to fig. 1, a detailed flowchart of an IP address assignment method provided in an embodiment of the present application is shown, where the method is applied to an address management server in a cloud platform system, where the address management server maintains a plurality of address pools, VLAN resource pools, a first association relationship between each service and its corresponding address pool, and a second association relationship between a tenant having at least one service and its assigned VLAN, and the method includes the following steps:
step 100: and when the target tenant is monitored to create the target business service, determining a target address pool corresponding to the target business service based on the first incidence relation.
In this embodiment of the present application, a plurality of address pools (IP address pools) are maintained in an address management server, and an address pool corresponding to each service is configured in advance based on a service type of each service, for example, if the service includes service 1, service 2, … …, and service n, the maintained address pools may include address pool 1, address pool 2, … …, and address pool n, and then, an association relationship between a service maintained in the address management server and its corresponding address pool may include: the address pool corresponding to the service 1 is the address pool 1, the address pool corresponding to the service 2 is the address pool 2, … …, and the address pool corresponding to the service n is the address pool n.
That is to say, when it is monitored that any tenant creates a virtual machine for running the service 1, it is determined that an address pool corresponding to the service 1 is the address pool 1, that is, an available IP address needs to be allocated to the virtual machine from the address pool 1, and when it is monitored that any tenant creates a virtual machine for running the service 2, it is determined that an address pool corresponding to the service 2 is the address pool 2, that is, an available IP address needs to be allocated to the virtual machine from the address pool 2.
Step 110: and acquiring the unallocated target IP address from the target address pool based on a preset IP address allocation rule.
In the embodiment of the present application, a preferred implementation manner is that the target address pool includes at least two sub-address pools; then, when the unallocated target IP address is obtained from the target address pool, a preferred implementation manner is to determine a target sub-address pool which is currently enabled and has no allocated IP address from the at least two sub-address pools; and acquiring the unallocated target IP address from the target sub-address pool.
For example, assuming that each address pool includes three sub-address pools, only one sub-address pool is enabled at the same time, for example, the destination address pool includes sub-address pool 1, sub-address pool 2, and sub-address pool 3, and the currently enabled sub-address pool is sub-address pool 1(IP address is not allocated), when it is monitored that the destination tenant creates a destination service, an unallocated destination IP address is obtained from sub-address pool 1 of the destination address pool.
It should be noted that, in the embodiment of the present application, a flag indicating whether each IP address in one sub-address pool is allocated to a virtual machine is set, where if the IP address is allocated to a virtual machine for use, the IP address is marked as allocated (e.g., a state flag is 1), and if the IP address is not allocated to a virtual machine for use, the IP address is marked as unallocated (e.g., a state flag is 0).
Step 120: and judging whether the corresponding first VLAN is distributed to the target tenant or not based on the second association relation.
In the embodiment of the application, a VLAN resource pool is also maintained in the address management server, and if at least one service is currently created by a tenant, it indicates that the tenant is already assigned with a corresponding VLAN, and an association relationship between the tenant and the VLAN assigned to the tenant is locally maintained.
That is to say, if a tenant does not currently have a created service, when the tenant creates a first service, the tenant allocates a corresponding VLAN to the tenant, and locally maintains an association relationship between the tenant and the VLAN allocated to the tenant. Subsequently, on the premise that the first service created by the tenant is not deleted, when the tenant creates another service, it may be determined that the corresponding VLAN is allocated to the tenant.
Step 130: and if the target tenant is judged to be allocated with the corresponding first VLAN, the target IP address and the first VLAN are issued to a target virtual machine for running the target service, and the target IP address is marked as allocated in the target address pool.
Specifically, if the association relationship between the target tenant and the first VLAN is determined to be maintained locally based on the second association relationship, it may be determined that the target tenant is already assigned with the corresponding VLAN, and it is not necessary to obtain an unassigned VLAN from the VLAN resource pool. At this time, the determined target IP address and the first VLAN may be directly sent to a target virtual machine for a target service of a target tenant, which is created on the cloud platform, so that the target virtual machine performs network configuration based on the target IP address and the first VLAN. Meanwhile, the destination IP address may be marked as allocated in the destination address pool. Obviously, the IP addresses marked as allocated cannot be reallocated for use by other virtual machines.
Further, if it is determined that the target tenant is not assigned with the corresponding first VLAN, acquiring an unassigned second VLAN from the VLAN resource pool based on a preset VLAN assignment rule; and issuing the target IP address and the second VLAN to a target virtual machine for running the target service, marking the target IP address as allocated in the target address pool, and marking the second VLAN as allocated in the VLAN resource pool.
That is, the target service created by the target tenant is the first service created currently, and a VLAN is not allocated to the target tenant before the target service, at this time, an unallocated VLAN needs to be obtained from the VLAN resource pool, and the VLAN is allocated to the target tenant, and after the VLAN is issued to the target virtual machine, the VLAN is marked as allocated in the VLAN resource pool. Obviously, VLANs marked as allocated cannot be reallocated for use by other tenants.
Further, in this embodiment of the present application, the IP address allocation method may further include the following steps: when any service of any tenant is detected to be deleted, the IP address allocated to the virtual machine for running any service is recovered, and the IP address is marked as unallocated in the address pool where the IP address is located.
That is, when a business service (virtual machine corresponding to the business service) of a tenant is deleted, the IP address allocated to the business service is reclaimed, and the IP address is marked as unallocated in the address pool.
Furthermore, in this embodiment of the present application, the IP address allocation method may further include the following steps: judging whether any tenant has other established business services; if it is determined that any tenant does not have any other created service, the VLAN allocated to any tenant is retrieved, and the VLAN is marked as unallocated in the VLAN resource pool.
That is, when all the service services created by a tenant are deleted (the virtual machine corresponding to the service is deleted), the VLAN assigned to the tenant may be received, and the VLAN is marked as unassigned in the VLAN resource pool.
The IP address allocation method provided in the embodiments of the present application is described in detail below with reference to specific application scenarios. For example, referring to fig. 2, a process schematic diagram of an IP address allocation method provided in this embodiment of the present application is assumed that an address pool corresponding to a service 1 maintained by an IP address allocation server is an address pool 1, the address pool 1 includes a sub-address pool 11, a sub-address pool 12 and a sub-address pool 13, an address pool corresponding to a service 2 is an address pool 2, the address pool 2 includes a sub-address pool 21, a sub-address pool 22 and a sub-address pool 23, the IP address allocation server further maintains a VLAN resource pool, and detailed description is given by taking an example of creating the service 1 by the tenant 1, the tenant 1 performs operations of a common service 1 through a client, at this time, a CAS (Cloud Automation System, Cloud computing management platform) creates a VM1 for running the service 1 created by the tenant 1, and accordingly, the address pool management server monitors operations created by the VM1, and the address management server needs to allocate an IP address and a VLAN1, the address management server determines that an address pool corresponding to the business service 1 is an address pool 1, and a sub-address pool which is enabled in the address pool 1 and has no allocated IP address is a sub-address pool 11, the address pool management server can acquire an IP address (such as the IP address 1) from the sub-address pool 11, further, the address pool management server judges whether a VLAN is allocated to the tenant 1, if the VLAN is allocated (such as other business services are established before the tenant 1 establishes the business service 1, and when other business services are established, a VLAN is allocated to the tenant 1), the allocated VLAN (such as the VLAN1) is acquired, and finally, the acquired IP address 1 and the VLAN1 are sent to a CAS platform, so that the VM platform performs network configuration on the CAS platform for VM 1; further, when the CAS platform deletes the VM1 corresponding to the service 1, the IP address 1 is released, and it is determined whether the VLAN1 needs to be released according to a judgment basis of whether all the service currently created by the tenant 1 is deleted.
Preferably, in this embodiment of the present application, the IP addresses stored in one address pool or one sub-address pool of the address pool in the address management server are IP addresses of the same network segment.
