AWS Virtual Private Clouds (VPCs)

A Virtual Private Cloud (VPC) is a logically isolated section of the Amazon Web Services (AWS) cloud in which you can launch AWS resources such as VMs within a virtual network.

Each VPC is dedicated to an AWS account and region. Each VPC also specifies a set of IP addresses to be used for a subnet associated with the VPC.

VPCs enable you to build a virtual network in the AWS cloud. VPNs, hardware, or physical datacenters are not required. You can define your own network space and control how your network, and the Amazon EC2 resources inside your network, are exposed to the Internet.

When requesting (provisioning) an instance, you can select the VPC and subnet that the EC2 belongs to.

To view a list of the VPC security groups, you must first provision a VM.

About this task

A security group acts as a virtual firewall for an instance to control inbound and outbound traffic.

When you launch a VM in a VPC, up to five security groups can be assigned to the instance. Security groups act at the instance level, not the subnet level. Each instance in a subnet in your VPC, therefore, could be assigned to a different set of security groups. When provisioned, an instance is automatically assigned to the default security group for the VPC.

Each security group has a set of rules that control the inbound traffic to instances, and a separate set of rules that control the outbound traffic.

Note: Amazon EC2-Classic is not supported.

Procedure

  1. Navigate to Amazon AWS Cloud > Configuration > Accounts.
