Cloud resource arrangement method based on cloud function and BPMN specification

Abstract

The invention discloses a cloud resource arrangement method based on a cloud function and a BPMN specification. The method comprises the steps that a BPMN process engine analyzes task information and issues the task information to a cloud message service; the cloud message service triggers and starts a Lambda cloud function service according to the task information, and a corresponding Lambda function set is selected; the Lambda cloud function service schedules the Lambda function set to a cloud function engine, and the cloud function engine executes a cloud function to enable the Lambda cloud function service to complete a task event; the Lambda cloud function service issues the completed task event to the BPMN process engine through the cloud message service; and the BPMN process engine analyzes the next task information. Execution logic and scheduling logic are separated, so that a process engine server side focuses on the scheduling logic of a process, a lightweight execution unit based on a cloud function is kept, and the method has good framework characteristics of cross-language, high expansion, distribution and heterogeneous deployment; according to the function set-oriented research and development mode, research and development concentrate on codes, and do not need to pay attention to the problems of code operation architecture, operation and maintenance implementation and the like, so that the research and development efficiency is improved, and the maintenance cost is reduced.

Description

Technical field[0001]The present invention relates to the field of cloud computing, and more particularly to a cloud resource arranging method based on a cloud function and a BPMN specification.Background technique[0002]The type of cloud resource includes IAAS, PaaS, SaaS, and application layers, different CPU architecture, and different CPU architecture, the scheduling method of cloud resources of different virtualization architectures is different, and the rolling control of cloud resource delivery is high, and has a diversity of organizational objects. Strong scalability and the characteristics of complexity process. BPMN (Business Process Model and notaration) is a visual graphical description method for business process model definition. Since BPMN is a very mature business process control specification, using the BPMN specification can solve the problem of complexity of cloud resource arranging process.[0003]The process control problem of deployment procedures is solved by pro...

Problems solved by technology

However, with the continuous increase of cloud resources, more implementation classes need to be added, and the demand response cost for new cloud resource orchestration objects is high and slow; the scheme of implementing execution logic through service classes will concentrate a large amount of business logic in The engine server side makes the engine server side more and more bloated, which seriously affects R&D management and operation and maintenance support, and also leads to the entire program architecture being a centralized architecture, which cannot be deployed in a distributed manner, and cannot expand its response capability for a large number of deployment requests , the centralized execution logic limits the simplification of the deployment architecture when the program is running. In certain scenarios, such as cross-arm and x86 scenarios, it cannot respond to the requirements of heterogeneous deployment; the selected framework of the process engine will limit the programming language of the service class choose
