HeROsim: An Allocation and Scheduling Simulator for Evaluating Serverless Orchestration Policies

This is the authors' abstract. We don't add key points for this paper.

Optimizing a serverless platform for quality of service is known to be a hard problem that requires experimenting with production data. For this sake, we propose a heterogeneous resources orchestration simulator (HeROsim) for the serverless service model. HeROsim allows the evaluation of resource allocation and task placement policies. HeROsim is an open source, fine-grained discrete-event simulator that considers data and temporal dependencies between functions deployed on heterogeneous resources. It replays execution traces from previously characterized workloads, extracts quality-of-service metrics from the scenarios and presents them to the user by generating summary charts.
