 One default VPC (**V**irtual **P**rivate **C**loud) for every available region is automatically created in each Scaleway [Project](/organizations-and-projects/concepts/#project). A VPC offers layer 3 network isolation.
 
-Within each VPC, you can create multiple **Private Networks** and attach Scaleway resources to them, as long as the resources are in an AZ within the network's region. Attached resources can then communicate between themselves in an isolated and secure layer 2 network, away from the public internet.

Attached resources can then communicate between themselves in an isolated and secure layer 2 network, away from the public internet. VPC routing facilitates communication between resources on the different Private Networks within the VPC.
 
 In the future, VPC will allow you to interconnect your VPC with other networks, define access control lists and more.
