Inter-VPC connectivityClassic Private Gateway

- not flexible (point-to-point)=>connecting 2+ VPCs requires extra routing (manual work) NSX L3/inter-vpc vm

- need to manually create lswitch in NSX - need to add private gw as root user

This was hard to automate.(but used in all cloud designs…)

Inter-VPC connectivityCosmic 5.3 Private Gateways

1. Create a network of type=Private 2. Use Private Gateway to connect it to any VPC 3. Make VPCs aware of each other using Static Routes

All straight from the Cosmic 5.3 UI / API(using domain-admin credentials)
