Query: Benchmarking Parallelism in FaaS Platforms   Serverless computing has seen a myriad of work exploring its potential. Some
systems tackle Function-as-a-Service (FaaS) properties on automatic elasticity
and scale to run highly-parallel computing jobs. However, they focus on
specific platforms and convey that their ideas can be extrapolated to any FaaS
runtime.
  An important question arises: do all FaaS platforms fit parallel
computations? In this paper, we argue that not all of them provide the
necessary means to host highly-parallel applications. To validate our
hypothesis, we create a comparative framework and categorize the architectures
of four cloud FaaS offerings, emphasizing parallel performance. We attest and
extend this description with an empirical experiment that consists in plotting
in deep detail the evolution of a parallel computing job on each service.
  The analysis of our results evinces that FaaS is not inherently good for
parallel computations and architectural differences across platforms are
decisive to categorize their performance. A key insight is the importance of
virtualization technologies and the scheduling approach of FaaS platforms.
Parallelism improves with lighter virtualization and proactive scheduling due
to finer resource allocation and faster elasticity. This causes some platforms
like AWS and IBM to perform well for highly-parallel computations, while others
such as Azure present difficulties to achieve the required parallelism degree.
Consequently, the information in this paper becomes of special interest to help
users choose the most adequate infrastructure for their parallel applications.
