VPC Flow Logs for Cross-Cloud Network

Gaining visibility into your network traffic is crucial, particularly with hybrid environments encompassing both on-premises and cross-cloud infrastructure. VPC Flow Logs have long been a staple to obtain detailed records of network traffic to, from, and within your Google Cloud subnets. But with the rise of more complex network topologies enabled by the Cross-Cloud Network, we knew we needed to expand VPC Flow Logs to give you a more complete picture.

That's why we're excited to share that you can now enable VPC Flow Logs directly on your Cloud VPN tunnels and VLAN attachments for Cloud Interconnect and Cross-Cloud Interconnect. This enhancement provides comprehensive monitoring of critical network traffic moving between your on-prem infrastructure, cross-cloud resources, and Google Cloud. With this new capability, you can:

• Gain granular insights: Log network flows passing through Cloud Interconnect and Cloud VPN with 5-tuple granularity (source/destination IP, source/destination port, protocol ...
