Openwhisk service-free framework migration method for micro-service application

Abstract

The invention discloses an openwhisk service-free framework migration method for a micro-service application, which comprises the following steps of: generating abstract syntax tree nodes by utilizing an exprima grammar analysis tool of a Node.js language, extracting key information from the abstract syntax tree nodes to generate a function call graph and a communication graph between micro-service sub-modules, judging the properties of the micro-service sub-modules, trying to divide stateful micro-service modules, and achieving automatic migration to the greatest extent. Project source code files, project package files, configuration files and the like are analyzed from the level of the abstract syntax tree, implementation is easy, and efficiency is high. At present, no similar technical scheme exists, and developers can be helped to improve the efficiency of migrating the application to the server-free computing platform by using the method.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to an openwhisk serverless framework migration method for microservice applications. Background technique [0002] With the rapid development of the Internet, the software architecture has also undergone earth-shaking changes. Microservices (Microservices) is a software architecture pattern developed from domain-driven design, continuous delivery, platform and infrastructure automation, scalable systems, multi-language programming, and persistence. Microservice does not have a clear definition, it is a relative concept. In a traditional monolithic application, all functional modules are concentrated in one service, and the user interface, data access layer, and data storage layer are tightly coupled. In the software architecture of microservices, each functional module is split into loosely coupled components, and tasks are performed through coordination. These function...

Problems solved by technology

If the next request of the service may need to rely on the data stored in memory and files, the service will not be able to provide normal services after migration

Therefore, for a microservice application composed of multiple microservice submodules, not all microservice submodules are suitable for migrating to a serverless computing architecture. One challenge of automated migration is to detect and identify microservice submodules suitable for migration and complete Migration, for microservice submodules that are not suitable for migration, specific reasons need to be detected for microservice submodules that are not suitable for migration. However, there is currently no more effective solution
