Architectural Design Patterns 8 – Serverless (Function as a Service – FaaS)
Today's topic is a quite popular one, a fuzzy word getting more and more popular once it used to be a niche architectural pattern only. When we think about building software, a lot of the time and energy is spent thinking about where and how it will run. Serverless architecture, also known as Function as a Service or FaaS, helps this to change. Instead of planning the environment to run, developers mainly write functions and let cloud providers like AWS or Azure handle where it runs. Briefly describing, Serverless is an architectural model where cloud providers fully manage code execution.…
