container orchestration

Continuing on from part 2 where we introduced the concept of container registries to distritbute immutable container images, in the article we are going a step further and introducing the concept of container orchestration. In our small example application we have four containers but in real world applications, especially in microservice architectures, a lot more containers make up the application’s architecture. This is very difficult to manage using manual methods, instead container orchestration tools are used to deploy and manage these applications on top of a fleet of servers (usually virtual machines) on a cloud infractructure.
