Microservices are one of the most important and popular software architecture trends. This architecture forms the base for a lot of companies including: Amazon, Netflix, Spotify, and Uber. 

In this course you’ll learn microservices in depth and understand reasons for and against microservices. Beyond that, you’ll learn about Micro and Macro architecture, strategies for migrating old systems, the role of Docker in this architecture, and technologies for implementing microservices. 

After taking this course, you’ll be better equipped to implement microservices for your own use.

An Introduction to Microservice Principles and Concepts

A technology for implementing microservices has to fulfill different requirements. The figure below gives us a birds-eye view of what these are.

We'll be discussing each of these in detail below.

# Communication 

Microservices have to **communicate** with *other microservices*. This requires **UI integration** in the **web UI** or **protocols** such as **REST** or **messaging**. 
>It is a *macro architecture decision* which communication protocol is used (see [Architecture Decisions](https://www.educative.io/courses/introduction-microservice-principles-concepts/architecture-decisions)).

However, the microservices have to support the chosen communication mechanism. Therefore, 
>The macro architecture decision influences the micro architecture. 

The technology choices at the micro architecture level have to ensure that the communication protocol defined by the macro architecture can really be implemented in each microservice.

In principle, every modern programming technology can support the typical communication protocols. Therefore, this requirement does not represent a real restriction.




In this lesson, we'll discuss the requirements a technology for implementing microservices has to fulfill.
