What is Amazon VPC?
VPC (Virtual Privat Cloud) is a virtual network, which is logically isolated from other virtual networks in the AWS Cloud. It is dedicated to you AWS account. It is master subnet, which you can use to create smaller subnets. VPC is created per region and it spans all Availability Zones in this region. You must specify an IP address range for the VPC (Classless Inter-Domain Routing (CIDR) block, for example 192.168.0.0/16).
