Explore different technologies for the implementation of microservices while highlighting their advantages and disadvantages.

Microservices Architecture

This module focuses on the various implementations of microservices. We’ll learn approaches for tech stacks that can be used to implement microservices. We’ll also discuss the pros and cons of each approach.
We’ll start by exploring some fundamental concepts for implementing microservices. Within each concept, we’ll learn about the different technologies used to implement it. The technologies include front-end integration with Edge Side Includes (ESI), asynchronous microservices with Kafka and REST feeds, synchronous microservices with the Netflix stack, and Consul, Docker, Kubernetes, and Cloud Foundry. Each technology is described and then demonstrated with real code.

Microservices Architecture: Practical Implementation

## Summary

- **Asynchronous communication should be preferred over synchronous communication** between microservices due to the advantages concerning resilience and decoupling. 

- **The only reason against this is
inconsistency**. Therefore, it is important to know exactly what the
requirements are, especially concerning consistency, in order to make the
technically correct decision. 

- Choosing asynchronous communication has
**the potential to solve the essential challenges** of the
microservices architecture and should, therefore, be considered in any
case.
