Learn to implement microservices across a range of common tech stacks.

Scalability & System Design for Developers

In this module, we’ll look at some fundamental concepts for implementing microservices. Within each concept, 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, Cloud Foundry. Each technology is described and then demonstrated with real code.

Microservice Architecture: Practical Implementation

There are different options for frontend integration. 

## Links
The easiest options are links. **One frontend displays a link that another frontend handles**. The World Wide Web (WWW) is based on precisely this mechanism, a system creating a link to another system.


## Redirects
*Redirects* represent another option. 

For example, **OAuth2** uses this approach:

- A website provides a link to an OAuth2 provider such as Facebook or Google. 
- The user enters their password and confirms that the website is allowed to access certain information. 
- The user is then redirected back to the original website by another redirect. Behind the scenes, the website receives the user's data. 

Redirects can combine frontend integration with data transfer in the background.
