Are these environments?

- My local laptop, IDE, CLIs, etc
- A local Kubernetes clusters using minishift or other

- A Virtual Machine that I need to login using SSH
- OpenShift hosted on Google Cloud

Environments have in common:

- Must provide the application’s infrastructure
- Someone must configure all this infrastructure
