    abstract = {Function-as-a-Service (FaaS) is a cloud service model enabling developers to
      offload event-driven executable snippets of code. The execution and management
      of such functions becomes a FaaS provider{\^a}€™s responsibility, therein included
      their on-demand provisioning and automatic scaling. Key enablers for this cloud
      service model are FaaS platforms, e.g., AWS Lambda, Microsoft Azure Functions,
      or OpenFaaS. At the same time, the choice of the most appropriate FaaS platform
      for deploying and running a serverless application is not trivial, as various
      organizational and technical aspects have to be taken into account. In this
      work, we present (i) a FaaS platform classification framework derived using a
      multivocal review and (ii) a technology review of the ten most prominent FaaS
      platforms, based on the proposed classification framework. We also present a
      FaaS platform selection support system, called FaaStener, which can help
      researchers and practitioners to choose the FaaS platform most suited for their
      requirements.},
