In a serverless world, your applications get dynamically provisioned and destroyed at the discretion of the platform you're using. This makes relying on resources like local memory, local variables, or even local disk storage almost impossible. Of course, you always have the option of using a database or a 3rd party caching service, but that may start complicating the code you have to write. In the latest release of Azure Functions, the team has added support for a new concept called Durable Entities, which lets you use similar patterns as you would see in an actor model style application. In this session, I will explore how you can leverage Durable Entities in your applications.
