Abstract

The invention relates to an edge computing service instance cross-node scaling method and device. The method comprises the following steps of: receiving a scaling request of the service instance; according to the scalable request, obtaining a first queuing delay of the current edge computing node and a second queuing delay of the target edge computing node; according to the first queuing time delay and the second queuing time delay, determining the average time delay of the service instance in operation; according to the average time delay, the performance parameter of the current edge computing node and the performance parameter of the target edge computing node, constructing a decision model, determining a scaling behavior corresponding to the scaling request according to the decision model, the scaling behavior including service instance copying, service instance extension, service instance migration and service instance combination, and performing service instance cross-node scaling according to the scaling behavior. By adopting the method, the user service interruption time can be greatly reduced when the node is expanded and contracted.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for scaling service instances across nodes in edge computing. Background technique [0002] Microservice architecture is one of the mainstream architectures used in current software development. Compared with the traditional single software development method, it can decompose a large software into several service modules with specific functions, and carry out independent deployment and operation and maintenance , so it has the advantages of easy scalability, high modularity, and convenient on-demand deployment, and is widely used in the development of distributed software. With the continuous development of edge computing, the micro-service architecture is constantly integrated with the edge computing model. The service modules designed based on the micro-service architecture are deployed in large numbers on the cloud and edge computing nodes. In ...
