It’s an extension of Azure Functions that allow you to write stateful executions in a serverless environment. Think of it this way. There are a few big benefits that people tend to focus on when they talk about Serverless Functions: They’re cheap They scale with your needs (not necessarily, but that’s the default for many services) They allow you to write event-driven code Let’s talk about that last one for a minute. When you can write event-driven code, you can break your operational needs down into smaller functions that essentially say: when this request comes in, run this code. You don’t mess around with infrastructure, that’s taken care of for you. It’s a pretty compelling concept. In this paradigm, you can break your workflow down into smaller, reusable pieces which, in turn, can make them easier to maintain. This also allows you to focus on your business logic because you’re boiling things down to the simplest code you need run on your server. So, here’s where Durable Functions come in. You can probably guess that you’re going to need more than one function to run as your application grows in size and has to maintain more states. And, in many cases, you’ll need to coordinate them and specify...
