You are designing a shared VPC architecture. Your network and security team has strict controls over which routes are exposed between departments. Your Production and Staging departments can communicate with each other, but only via specific networks. You want to follow Google-recommended practices.
How should you design this topology?
You recently deployed two network virtual appliances in us-central1. Your network appliances provide connectivity to your on-premises network, 10.0.0.0/8. You need to configure the routing for your Virtual Private Cloud (VPC). Your design must meet the following requirements:
All access to your on-premises network must go through the network virtual appliances.
Allow on-premises access in the event of a single network virtual appliance failure.
Both network virtual appliances must be used simultaneously.
Which method should you use to accomplish this?
