Why Serverless Doesn’t Always Mean Stateless

Why Serverless Doesn’t Always Mean Stateless

Function as a Service (FaaS) is a common approach to serverless architectures across cloud vendors. FaaS works because it’s opinionated. Each cloud vendor has their own offering with constraints (AWS Lambda, Azure Functions, Google Cloud Functions, to name a few). What the customer gets in return is true utility pricing and the promise of a scalable architecture built of stateless building blocks.

Successful deployments will require a different mindset than used for monolithic apps. In my situation, I’m tilted towards stitching it all back together, given that I work in integration. Once that monolithic app is broken up into stateless functions, how is it best joined together into something that behaves like the original app?
