Other serverless architectures

There are many other serverless options, such as OpenFaaS, Fission, and Iron.io. I won't cover them in this book, but let's scheme through the features. OpenFaaS is an open source alternative for serverless architecture. It is built over Docker containers, Swarm, and Kubernetes. It has its own UI portal and also has CLI support to deploy functions. OpenFaaS supports Node.js, Python, GO, and C# on Windows and Linux. We can set it up over a cloud, a local laptop, or an on-premise server. We can write functions for almost everything—that is what is claimed by OpenFaas. OpenFaaS is written in Golang. It allows events through HTTP/HTTPS requests.

Fission is yet another open source version of serverless architecture—the underlying technology is Kubernetes and Docker containers, which can be deployed on both cloud and on-premise infrastructures. It is designed as a set of microservices, and its components are the controller, router, and pool manager. The router manages HTTP requests, the controller manages functions, event triggers, and environment images, and the pool manager manages the pool of containers and loads the functions into these containers. The functions are written with Python.
