You might have heard about serverless technologies and their advantages: Simpler development and lightspeed deployment of features. Serverless prevents us developers from dealing with infrastructure componentes, the most annoying thing in software development. But in the end its just one more layer of application abstraction. Maybe you heard about Event Sourcing (ES), too. Event Sourcing is one of the most disrupting patterns from the last years and is based on the concept of an Event Store. So, both Serverless and ES are extremely useful. Why not combine it to one thing: The Serverless EventStore? In this talk you will learn how and why Serverless Technologies are so important, as well as why Event Sourcing kicks you into the future (by using the history). I will show you how to set up a serverless EventStore in the Azure Cloud with Azure Functions and a Custom Binding.
