FaaS, or Functions as a Service, is a relatively new offering that you can hardly miss nowadays. Some see it as a successor to Platform as a Service, others see just another way of hosting your application functionalities. The major cloud providers also stepped into this area and offer serverless computing capabilities. As always, your application needs to run somewhere, so it is a nice marketing term for a hosting solution that allows you to make efficient use of available resources by running short-lived pieces of code, which are small, usually stateless, and on demand. OpenFaaS is a project that makes use of Docker containers to convert any process into a serverless function, regardless of the programming language of the code.
