S-FaaS

Abstract

Function-as-a-Service (FaaS) is a recent and popular cloud computing paradigm in which the function provider specifies a function to be run and is billed only for the computational resources used by that function. Compared to other cloud paradigms, FaaS requires significantly more fine-grained measurement of functions' compute time and memory usage. Since functions are short and stateless, small ephemeral entities (e.g. individuals or underutilized data centers) can become FaaS service providers. However, this exacerbates the already substantial challenges of 1) ensuring integrity of computation, 2) minimizing information revealed to the service provider, and 3) accurately measuring computational resource usage.
