DRAFT: AAW Architecture: Investigate same-cluster isolation of platform level deployments

[Souheil-Yazji]

Preface

Currently, our dev cluster provides very little value to us. In-cluster isolation is a huge boon of K8s, maybe we can use that to simply drop the dev cluster by using "Dev" namespaces and label selection logic in the appropriate places.

We'd definitely have to consult Cloud Native Solutions on this approach, but I feel like it's feasible and possibly even better due to the scale of our ops.

Describe the solution you'd like

• investigate the possiblity of using "dev" labeled namespaces to isolate dev-tiered deployments and prod-tiered deployments.
• create a map itemizing the scope of changes introduced with such an initiative, this definitely is not trivial. One example is network policy management and profile-controller states.
