eigr.io – a Serverless Runtime on the BEAM (ACM SIGPLAN, ICFP 2021 Erlang Workshop)
Serverless runtimes are often hidden in a cloud providers offering and exposed solely by their programming API and deployment procedures. In this talk, we’ll explore an open-source Serverless runtime built for the cloud and on-premises, running on the BEAM with a polyglot programming model to build general purpose applications. Building general purpose applications using multiple languages and having a story how to handle state was our main motivation to explore the space of a Serverless runtime to be built. We think the BEAM, OTP and Elixir/Erlang are a perfect match to build on. With this talk, we combine herein the world of the BEAM with cloud technology like a gRPC-based protocol, Kubernetes and a polyglot programming model with languages supported like Go, JavaScript, JVM-languages, Python and many more. https://icfp21.sigplan.org/details/erlang-2021-papers/13/Lightning-Talk-eigr-io-A-Serverless-Runtime-on-the-BEAM
