- Create a Kubernetes cluster in AWS (AVAILABLE)
- Run your templates in the AWS cluster (AVAILABLE)
- Create AWS Volumes for persisting your container's data (AVAILABLE)
- Inspecting and troubleshooting problems in the cluster
- Run updates to your code with the new concept of "deployments" (AVAILABLE)
