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


# Micro architectural decisions
If decisions can actually be **different for each microservice**, then they are part of the **micro architecture**. 

Decisions at the micro architecture level are better suited to the self-organization of teams and use the technical freedom offered by microservices. 

Even if decisions are part of the micro architecture,  a team can still standardize because using technologies with which other teams already had positive experiences decreases the risk and allows for synergy.

# Macro architectural decisions
The **macro architecture**, on the other hand,
contains those parts of the architecture that **apply uniformly to all microservices**. 

The division into these two levels gives the individual microservices freedom, while simultaneously ensuring the integrity of the overall system.

In all cases, decisions must be made explicitly. The teams must
consciously deal with the macro architecture and the freedoms in micro
architecture. Micro and macro architecture form a trade-off which is different in each project.

In this lesson, we'll formally conclude this chapter with some notes regarding decisions at the micro and macro architectural level.
