A container story..

Potting mix:

Preparing the environment

Reproducible results...

Periodic "operations"

Scaling out the business..

..can quickly become a nightmare

Why is it such a big deal?

Management of containers is a complex task

Need for a "Container Management Platform"

Reality is complex

Multiple containers per application (see "μservices")
Every app. with it's own container "recipe"
Containerized applications must communicate with each other
Containers are fragile and thus ephemeral

What is it?

Container Management Platform and much more
Hides the complexities of the underlying infrastructure
Deploys applications to containers and manages their operation throughout the entire application lifecycle
