What is the purpose of VPC in AWS?

The purpose of a Virtual Private Cloud (VPC) in AWS is to create a logically isolated network environment. This allows users to define and control their virtualized networking resources, such as IP address ranges, subnets, route tables, and network gateways. By leveraging a VPC, organizations can ensure the separation of their cloud resources from those of other AWS customers, establishing a secure and customized network suitable for their applications and workloads.

With a VPC, users can deploy resources in a manner that mirrors a traditional network but with the flexibility and scalability benefits of the cloud. They can set up public and private subnets, control access with security groups and network ACLs, and implement additional routing and connection options, such as VPN connections and peering with other VPCs. The ability to tailor the network infrastructure to meet specific security and operational needs is a critical feature that supports a wide range of use cases from simple web applications to complex enterprise systems.
