Multi-scene service elastic scaling method based on strategy model and related components

Abstract

The invention discloses a multi-scene service elastic scaling method based on a strategy model and a related component, and relates to the field of application service instance allocation, a server instance allocation strategy for each preset and specified application service is set, and the corresponding strategy adopted for the application service is determined according to a received user instruction. If the distribution strategy is a direct distribution strategy, distributing a corresponding number of server instances to each application service, and if the distribution strategy is a time distribution strategy, distributing a corresponding number of server instances at the current time to each application service according to the corresponding relationship between the current time and the server instances; if the load distribution strategy is the load distribution strategy, the corresponding number of server instances under the current load are distributed to each application service according to the load of each application service, the load capacity of the application services does not need to be manually detected in real time, and the number of the server instances distributed to each application service does not need to be manually adjusted; and the cost and workload of application service operation and maintenance are reduced.

Description

technical field [0001] The invention relates to the field of application service operation and maintenance, in particular to a multi-scene service elastic scaling method and related components based on a policy model. Background technique [0002] When a client accesses a specific application service, the application service handles the access through the server instances it owns. When the access volume is too large, the load of these server instances will also increase. If the total load of the server instances If the load exceeds the load quota allocated by the server to the application service, the application service will crash. If the number of server instances allocated to the application service is simply increased, when the total load of the application service is low, the application service will crash again. Causes a waste of server instance resources. In the prior art, when allocating server instances to a specific application service, the real-time total server ...

[0002] When a client accesses a specific application service, the application service handles the access through its own server instances. When the amount of access is too large, the load of these server instances will also increase accordingly. If the total load of the server instances If the amount exceeds the load quota allocated by the server to the application service, the application service will crash. If the number of server instances allocated to the application service is simply increased, when the total load of the applicati
