Google Cloud's Private Service Connect (PSC) enables secure access to Google Cloud services and third-party partner services within Virtual Private Clouds, keeping network traffic secure and reducing egress costs. Datadog is a Google Cloud partner with PSC, allowing customers to send high-volume network logs, load balancer logs, and VPC Flow Logs privately to Datadog, reducing data transfer costs and providing cost-effective analytics and long-term retention options. The Datadog-PSC integration enables monitoring of services consumed or produced via PSC, tracking network traffic flow, and optimizing costs and resources, with features such as alerts for bytes, dropped packets, and used IP addresses, allowing customers to fine-tune their service performance and detect anomalies.
