Abstract

A method includes obtaining a service availability level of a to-be-deployed service; determining, based on an availability policy library and according to the service availability level of the to-be-deployed service, availability-related parameter information of a resource corresponding to the service availability level of the to-be-deployed service; and allocating and configuring the corresponding resource for the to-be-deployed service based on a resource information library and according to the availability-related parameter information of the resource corresponding to the service availability level of the to-be-deployed service, where the resource includes at least one of the following: an infrastructure resource, a non-HA software resource, or an HA software resource.

First claim

What is claimed is:

1. A method, comprising:
obtaining a service availability level of a to-be-deployed service, wherein the service availability level is determined according to a service type of the to-be-deployed service, or the service availability level is determined according to a user type corresponding to the to-be-deployed service;
determining, based on an availability policy library and according to the service availability level of the to-be-deployed service, availability-related parameter information of a resource corresponding to the service availability level of the to-be-deployed service; and
allocating and configuring, for the to-be-deployed service, the resource corresponding to the service availability level of the to-be-deployed service based on a resource information library and according to the availability-related parameter information of the resource corresponding to the service availability level of the to-be-deployed service;
wherein the availability policy library stores an availability policy, and the availability policy comprises at least one service availability level and availability-related parameter information of a resource corresponding to each service availability level;
wherein the resource information library stores availability-related parameter information of a system-configured resource, and the system-configured resource comprises: an infrastructure resource, a non-high availability (HA) software resource, or an HA software resource; and
wherein the infrastructure resource comprises a hardware resource, a virtualization platform, a virtual unit, and a virtual resource, the hardware resource comprises a computing hardware resource, a storage hardware resource, and a network hardware resource, and the virtual resource comprises a virtual computing resource, a virtual storage resource, and a virtual network resource.

2. The method according to claim 1 , wherein before allocating and configuring, for the to-be-deployed service, the resource corresponding to the service availability level of the to-be-deployed service based on the resource information library and according to the availability-related parameter information of the resource corresponding to the service availability level of the to-be-deployed service, the method further comprises:
obtaining specification-related parameter information of the resource, wherein the specification-related parameter information of the resource comprises a resource quantity or resource performance; and
wherein allocating and configuring, for the to-be-deployed service, the resource corresponding to the service availability level of the to-be-deployed service based on the resource information library and according to the availability-related parameter information of the resource corresponding to the service availability level of the to-be-deployed service comprises:
allocating and configuring, for the to-be-deployed service, the resource corresponding to the service availability level of the to-be-deployed service based on the resource information library and according to the specification-related parameter information of the resource and the availability-related parameter information of the resource corresponding to the service availability level of the to-be-deployed service.

3. The method according to claim 1 , wherein the availability-related parameter information of the infrastructure resource comprises: a service life of the hardware resource, a manufacturer of the hardware resource, an enhanced reliability feature of the hardware resource, a redundancy quantity or ratio of the hardware resource, anti-affinity of the hardware resource, a manufacturer of the virtualization platform, a version of the virtualization platform, a redundancy quantity or ratio of the virtual unit, anti-affinity of the virtual unit, a redundancy quantity or ratio of the virtual resource, or anti-affinity of the virtual resource;
wherein the availability-related parameter information of the non-HA software resource comprises: a manufacturer of the non-HA software resource, a version of the non-HA software resource, a redundancy quantity or ratio of the non-HA software resource, or anti-affinity of the non-HA software resource, and the non-HA software resource comprises: a service chain, a virtualized network function (VNF), and a virtualized network function component (VNFC); and
wherein the availability-related parameter information of the HA software resource comprises a function type of the HA software resource or function parameter configuration of the HA software resource.

4. The method according to claim 1 , wherein the availability policy library further stores a service candidate policy or degradation policy; and
wherein the method further comprises:
allocating and configuring a another resource for the to-be-deployed service based on the resource information library and according to the service candidate policy or degradation policy when the availability-related parameter information that is of the system-configured resource and stored in the resource information library does not have parameter information matching the availability-related parameter information that is of the resource corresponding to the service availability level of the to-be-deployed service and determined based on the availability policy library.

5. A method, comprising:
when it is detected that an availability state of a deployed service changes, or when information that affects an availability state of the deployed service is detected, performing, based on an availability policy library and a resource information library, end-to-end adjustment on a resource configured for the deployed service;
wherein the availability policy library stores an availability policy, the availability policy comprises at least one service availability level and availability-related parameter information of a resource corresponding to each service availability level, and a service availability level of the deployed service is determined according to a service type of the deployed service, or the service availability level of the deployed service is determined according to a user type corresponding to the deployed service;
wherein the resource information library stores availability-related parameter information of a system-configured resource, the system-configured resource comprises: an infrastructure resource, a non-high availability (HA) software resource, or a HA software resource; and
wherein the infrastructure resource comprises a hardware resource, a virtualization platform, a virtual unit, and a virtual resource, the hardware resource comprises a computing hardware resource, a storage hardware resource, and a network hardware resource, and the virtual resource comprises a virtual computing resource, a virtual storage resource, and a virtual network resource.

6. The method according to claim 5 , wherein the availability-related parameter information of the infrastructure resource comprises a service life of the hardware resource, a manufacturer of the hardware resource, an enhanced reliability feature of the hardware resource, a redundancy quantity or ratio of the hardware resource, anti-affinity of the hardware resource, a manufacturer of the virtualization platform, a version of the virtualization platform, a redundancy quantity or ratio of the virtual unit, anti-affinity of the virtual unit, a redundancy quantity or ratio of the virtual resource, or anti-affinity of the virtual resource;
wherein the availability-related parameter information of the non-HA software resource comprises: a manufacturer of the non-HA software resource, a version of the non-HA software resource, a redundancy quantity or ratio of the non-HA software resource, or anti-affinity of the non-HA s
