By default, how many virtual private clouds (VPCs) can be created in each AWS region?

By default, the limit for the number of virtual private clouds (VPCs) that can be created in each AWS region is five. This limitation allows users to organize their network resources efficiently while still providing enough flexibility for various workloads. Each VPC can be tailored with its own subnet configurations, security settings, and route tables, allowing for isolated networking environments within the same AWS account and region.

The default limit of five VPCs per region helps manage resources effectively and encourages users to think carefully about their architecture and network design. If more VPCs are needed, AWS allows users to request an increase in this limit through the AWS Support Center, but for general use, the default of five provides a solid starting point for most applications.
