Q

<p>Amazon VPC</p>

A

<p>Amazon Virtual Private Cloud (Amazon VPC). Amazon VPC enables you to provision an isolated section of the AWS Cloud. In this isolated section, you can launch resources in a virtual network that you define. Within a virtual private cloud (VPC), you can organize your resources into subnets. A subnet is a section of a VPC that can contain resources such as Amazon EC2 instances.</p>
