AWS Virtual Private Cloud (VPC) is an isolated section of Amazon Web Services that allows allocation of AWS resources within a custom-defined virtual network, providing benefits such as single-tenant hardware, fine-grained egress and ingress filtering, and access control. Datadog's AWS VPC integration enables monitoring of all components within the VPC alongside EC2-classic components, allowing for correlation with other infrastructure metrics and gaining insight into app performance. With this integration, customers can automatically collect statuses of their VPC services, add custom tags, and set up custom monitors to alert on changes. The integration is available through a setup tile in Datadog's integrations list or by signing up for a trial, enabling comprehensive monitoring of VPCs with a flexible service.
