FaaS4FogSim

This repository contains the source code for the simulation software used within the paper Towards Auction-Based Function Placement in Serverless Fog Platforms:

The Function-as-a-Service (FaaS) paradigm has a lot of potential as a computing model for fog environments comprising both cloud and edge nodes. When the request rate exceeds capacity limits at the edge, some functions need to be offloaded from the edge towards the cloud. In this position paper, we propose an auction-based approach in which application developers bid on resources. This allows fog nodes to make a local decision about which functions to offload while maximizing revenue. For a first evaluation of our approach, we use simulation.

Using the simulation

• Import the project in IntelliJ and build it with Java and Kotlin
• Run MainKt and provide as argument:
  • sim1: study the effect of an increasing request load on the processing prices
  • sim2: study the effect of an increasing number of executables on storage prices
• Parameter choices for sim1 and sim2 are detailed in simResults/parameter_choices_paper_eval.txt
• The simulation is deterministic, the results and some analysis results for sim1 and sim2 are also available in simResults
• You can customize simulation parameters in the CONFIG class
