Virtual Private Cloud

AWS VPC is used to create a virtual network. This is typically used in concert with zk/Elastic_Compute_Cloud to manage connections to a virtual server both privately and accross the internet.

You define a network address range and then create subnets for managing different connections and functionality. You use a public subnet for resources that must be connected to the internet and a private subnet for resources that are to remain isolated from the internet.

The diagram below details a basic VPC configuration:

• Within a given AWS region we have created a VPC network.
• This comprises public and private subnets
• Both subnets host an EC2 instance
• The public subnet has a bridge to the internet through the Internet Gateway
• Both subnets have a routing table to manage requests and access
