Last Thursday, Google introduced a new feature to its Virtual Private Cloud (VPC) users for tracking network operations between their servers in the Google Cloud. Called VPC Flow Logs, the tool logs and monitors all network flows sent from and received by the virtual machines (VM) inside a VPC in five-second intervals.
The new feature is set to improve monitoring by Google Cloud Platform (GCP) admins and increase transparency in the VPC network, including traffic between Google Cloud regions. It is similar to Cisco’s NetFlow “but with additional features,” as explained in the company’s blog post.
