FaaSification and Serverless Functions Abstraction, Orchestration, and Distribution


Sashko Ristov, Researcher at DPS


Function-as-a-Service (FaaS) is a popular technology in recent years to develop and run cloud applications. Developers build and deploy their codes as serverless functions and the entire underlying platform and infrastructure is completely managed by cloud providers. However, FaaSification (conversion of existing monoliths to the FaaS architectural style) is challenging because serverless functions are isolated from each other. Further on, in order to exploit all benefits that FaaS paradigm offers, but also to overcome FaaS limitations, serverless functions can be orchestrated in a workflow, which may allow the runtime system to instantly spawn numerous functions. This talk will present our recent Dependency-Aware FaaSifier (DAF) that simplifies the creation of serverless functions, as well as techniques how to abstract, model, orchestrate, and distribute them across multiple FaaS providers.
