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

# Why Cloud Foundry?
[Cloud Foundry](https://www.cloudfoundry.org/) serves as PaaS technology for the example in this course. The following are the reasons for this:

## Open source
Cloud Foundry is an **open source project** involving a number of
companies. 

Cloud Foundry is managed by a **foundation**, in which Cloud Foundry providers such as **Pivotal, SAP, IBM, and Swisscom** are organized.


This ensures broad support in addition to the already many PaaS based on the Cloud Foundry.


## Easy to install
Cloud Foundry can be easily installed as a Pivotal Cloud Foundry for
Local Development on a *laptop* to set up a local PaaS for developers
to test microservices systems.

## Common
 There are many public cloud providers who have an offering based on
Cloud Foundry. An overview can be found at:
  <https://www.cloudfoundry.org/how-to-try-cloud-foundry/>.

## Can be installed on your own data center
 Finally, Cloud Foundry can be installed in your own data center.
[Pivotal Cloud Foundry](https://pivotal.io/platform) is, for example, an option for this.



In this chapter, we'll gain a quick introduction to the PaaS technology, Cloud Foundry.
