A Method of Dynamic Container Layer Replacement for Faster Service Providing on Resource-Limited Edge Nodes

As the edge cloud technology evolves, research is underway to provide customers with a serverless architecture-based FaaS (Function as a Service) on the edge nodes. However, serverless architecture-based FaaS on the edge nodes has a problem with resource management due to edge nodes with relatively lower computing power than the cloud data centers. And also it has a late service provision problem due to time to prepare cloud instances for customer API call requests. In this paper, we propose the method of dynamic container layer replacement considering a resource-limited environment on the edge nodes while mitigating cold start and then shows the performance.
