A Joint Resource Allocation and Request Dispatch Scheme for Performing Serverless Computing over Edge and Cloud

Serverless computing functions typically execute in the cloud. However, the high latency of accessing the cloud may require running them on edge servers, which have limited computing power and memory availability. This paper proposes a joint resource allocation and request dispatch scheme to execute serverless computing functions over edge and cloud collaboratively. This new scheme explicitly considers how to allocate server memory and operation budget for concurrent serverless computing requests considering the cold-start latency in design. The proposed scheme has been evaluated through extensive simulations. Its effectiveness has been proved by comparison with the upper-bound results.
