Problems solved by technology

Since the microservice programs of many virtual machines may be cross-called, if a microservice has an abnormal timeout at this time, the request will consume system threads, IO and other resources
When there are more and more requests of this type, more and more computer resources will be occupied; it will lead to system bottlenecks, causing requests from other microservices to be unavailable as well; eventually causing the entire platform to crash

Embodiment Construction

[0021] There are many implementations of the present invention, here we take the cloud platform as an example to illustrate one of the implementation methods, the flow chart is as follows figure 1 As shown, the specific implementation process is as follows

[0022] 1. Set the load balancing weight scheduling rules, the code is as follows:

[0023]

[0024]

[0025] Load balancing means that user requests are allocated to multiple microservices for execution, so as to jointly complete work tasks and quickly respond to user requests; the default scheduling rule is the best response time rule.

[0026] The weight scheduling rule means that the priority of the microservice whose number of failures exceeds the threshold per unit time is reduced to the lowest, and then other microservices with higher priority are selected according to the best response time rule; the unit time can be set, and the default is 5 minutes. The default threshold is 20 times;

[0027] The best resp...

Abstract

The invention relates to the technical field of the cloud platform micro-service, especially a method for defending micro-service avalanche effect. The method comprises the following steps: 1, settinga load balancing weight scheduling rule, and supporting the promotion and the demotion of the micro-service priority; 2, setting a circuit breaker; 3, starting the circuit breaker when the micro-service is abnormal; 4, starting the load balancing weight scheduling rule when the micro-service is failed; 5, turning off the circuit breaker when the micro-service is recovered; and 6, starting a loadbalancing default scheduling rule when the micro-service is recovered. Through the method disclosed by the invention, the problems of the system bottleneck and even the collapse of the whole platformcaused by the micro-service avalanche effect are solved, and the method can be applied to the micro-service management of a cloud platform.

Description

technical field [0001] The invention relates to the technical field of cloud platform microservices, in particular to a method for defending against the avalanche effect of microservices. Background technique [0002] There are a large number of service programs on a general cloud computing platform, and there may be multiple running microservice programs on each computing node or control node; and the computing nodes are also running multiple virtual machines. One or more microservice programs may also be running on each virtual machine. Since the microservice programs of many virtual machines may be cross-called, if a microservice has an abnormal timeout at this time, the request will consume system threads, IO and other resources. When there are more and more requests of this type, more and more computer resources will be occupied; it will lead to system bottlenecks, making requests from other microservices also unavailable; and eventually lead to the collapse of the ent...
