Virtual Private Cloud

Amazon Virtual Private Cloud (VPC) lets you logically isolate the portion of the AWS Cloud in a region. AWS provides one default VPC in each region so that you can be ready to spin up resources as soon as you sign up. You can create your own VPC and spin up resources within your VPC. The default VPC that you get has all the public subnets. You can use your own IP address range for creating a new VPC and can plan to extend your on-premise data center. The VPC network resembles a traditional network that you build on-premise. You can also control the traffic coming in and going out of your VPC. You can also generate a detailed flow log on the VPC, which will help you to do analysis on the traffic flowing in and out for a better security control.
