When AWS introduced the first Function-as-a-Service (FaaS) runtime, Lambda, in 2014 and subsequently enabled developers to evolve beyond Microserrvices to create Serverless application architectures, it was inevitable that there would eventually be on premises variants. At its core a FaaS runtime requires a container engine of some sort that it can insert functions into, so it is no surprise that almost four years after the Lambda announcement that there are now five FaaS runtimes installable on top of Kubernetes (K8S) that have more than 3,000 stars on GitHub. A sixth behemoth looms on that horizon as well.
A group of Cisco employees who are interested in this topic recently founded fonk-apps.io, a collection of simple web applications that run on the five FaaS runtimes with 3,000 or more stars on GitHub as a way of understanding this space better. In this blog we’ll explore the different approaches that each FaaS runtime takes and what the developer experience is like, summarized in this graphic: Read the complete article here.
