Hybrid connectivity links infrastructure environments such as public clouds and on-premises data centers. Within Anthos networking, it forms the lowest layer beneath cluster, multicluster, and service-to-service connectivity. section 10.0 section 10.5
Use the four-layer model to distinguish infrastructure links from Anthos cluster, multicluster, and application connectivity. section 10.0
Select the connection method according to network location, traffic volume, security requirements, and infrastructure ownership:
- Dedicated Interconnect provides a direct physical connection between an on-premises network and Google’s network, supporting large data transfers and potentially reducing bandwidth cost. section 10.5
- Cloud VPN extends a peer network through an encrypted IPsec tunnel over the public internet and suits low-volume data connections. section 10.5
- Public-internet connectivity requires no specialized networking hardware or software; TLS or mutual TLS secures service-to-service traffic. section 10.5
GCP environments can use a single VPC, shared VPC, or multiple VPCs. Non-GCP Anthos environments treat clusters as isolated networks, so connectivity design must account for these boundaries. section 10.5
