Customers using VPCs can execute code, store data, host websites, and do anything else that a private cloud can do, but the private cloud is hosted remotely by a public cloud provider. In AWS, a VPC is a specialized virtual network for your AWS account that is logically separated from the rest of the AWS cloud virtual networks.
