To understand what micro apps are on iOS, we first must look at what a “micro app” is. A micro app is a small, precise, highly specialized application. It is designed for a single use case. They can run independently, or you can combine several micro apps in pursuit of a more complex objective. Some example use cases include reading from or writing to an enterprise database, or sending alerts or notifications when a particular event occurs.

Microservices are small, independently-running applications that perform a single function for a larger application or IT infrastructure. By loosely connecting a number of them together, developers create a pluggable architecture that facilitates the process of updating, upgrading, and scaling the application in response to changing requirements.
