MicroServices

As of 2018 a big buzzword: An architectural style to structure an application as a collection of small and loosely coupled independent services.

Some of its principles:

Each microservice implements a single service capacity. Do one thing only and do it well
Consider and embrace failure
The service is elastic and resilient
There’s no Data sharing between microservices
Each microservice can be updated and deployed independently

To make the best out of microservices you must be able to:

Support quick provisioning
Monitor and report the state and functioning of the microservices in operation
Have a solid Devops Culture/Practice which means Continous Delivery
