This article covers an overview of Transit VPC Google cloud networks. In fact, transit connectivity is a solution where we can connect a network with multiple peered networks, it can act as a centralize transit hub through which we can route traffic to multiple VPCs together so it will save overall cost to set up multiple VPNs between networks.
VPC Network Peering is useful in these environments:
- SaaS (Software-as-a-Service) ecosystems in Google Cloud. You can make services available privately across different VPC networks within and across organizations.
- Organizations that have several network administrative domains that need to communicate using internal IP addresses.
