Google Cloud gives developers more insights into their networks
Summary
As the name implies, VPC Flow Logs are meant for businesses that already use Google’s Virtual Private Cloud features to isolate their resources from other users.VPC Flow Logs monitors and logs all the network flows (both UDP and TCP) that are sent from and received by the virtual machines inside a VPC, including traffic between Google Cloud regions.The data updates every five seconds and Google promises that using this service has no impact on the performance of your deployed applications.In addition, it will allow them to optimize their network usage and costs by giving them more information about their global traffic.If that’s your main use case, though, you probably want to export your data to a specialized security information and event management (SIEM) platform from vendors like Splunk or ArcSight.
