A Virtual Private Cloud, or VPC, is an isolated network area inside a public cloud. It lets teams organize cloud resources with their own subnets, routing, IP ranges, firewall rules, and network connections.
What a VPC controls
A VPC can separate workloads, limit exposure, connect to private networks, and define which resources can communicate. It is one of the basic building blocks of cloud networking.
VPC and cloud security
A VPC is not a complete security plan by itself, but it supports segmentation and access control. It often works with cloud firewalls and identity controls.
In practical terms, a VPC is your cloud network boundary.
