Inter-network communication design with ncc vpc peering

Connecting hybrid environments to the cloud is a very important aspect of cloud architecture. In addition to connecting from on-premises environments, you also have multicloud environments that all need to communicate. In this blog we will look at some reference architectures for hub-and-spoke communication using Cross-Cloud Network.

The power of Cross-Cloud Network

As your cloud projects grow and you add additional networks, you need inter-network communication. Cross-Cloud Network provides a set of functionality and architectures for any-to-any connectivity leveraging Google’s software-defined global scaled backbone to connect your distributed applications.

Let’s look at two architectural patterns: one based on VPC Network Peering, and the other on Network Connectivity Center.

#1 - Inter-VPC communication with VPC Network Peering example pattern

To understand how to think about designing your network, let's look at the flow of a packet from an external network to an application located in workload VPC network 1 ...
