Design and Implementation of an Improved Serverless Edge Computing Framework Based on Workflow
Edge computing has many advantages,such as high performance,small volume and strong computing power.However,the edge computing function chain designed by the cloud has a long call delay,which may lead to difficult collaboration between the cloud and the device,and an unsatisfactory seamless docking effect.Therefore,this paper designed a serverless edge computing framework(SECP)based on OpenFaas,which provides computing serv-ices based on stateless functions for the edge side.Firstly,the invocation procedure of the computing service was mod-eled and analyzed,and then the workflow model was used to improve the problem of function chain invocation delay amplification existing on the edge side of the serverless computing designed for the cloud.The test result shows that SECP has good performance in edge computation,reduces the response time of service requests in the edge computing platform,solves the problem of single function of serverless computing,improves the utilization rate of edge resources,and improves the problem of complicated deployment and maintenance of edge computing services.
