Types are probably the last thing that comes to your mind when someone mentions microservices. The aim of this talk is to change this misconception. Rumyana will share with you that types can be used to understand, test, specify and verify microservices. In particular, she will give you a crash course on session types, which were born as types for distributed processes. Session types are not that different than youр normal data types. In the same way that you have string and int to describe the data in your application, a session type describes the constraints on the interactions between components. For example, a simple session type can specify that a service is expected to send an int, and then to receive a string. Simple, right?
