Virtual networking with Amazon EC2

Nigel Duke 16 March 2011 0

Amazon have announced the release of several new features for Amazon EC2 (Amazon Elastic Compute Cloud).  Each feature taken on its own may not be ground-breaking but combine to offer virtual networking on EC2.

  • A new VPC Wizard to streamline the setup process for a new VPC.
  • Full control of network topology including subnets and routing.
  • Access controls at the subnet and instance level, including rules for outbound traffic.
  • Internet access via an Internet Gateway.
  • Elastic IP Addresses for EC2 instances within a VPC.
  • Support for Network Address Translation (NAT).
  • Option to create a VPC (Virtual Private Cloud) that does not have a VPN connection.

In theory, with EC2 it’s possible to create a virtual network topology that closely resembles a physical data centre, making it possible to create (or re-create) a network programatically and realise it at any given point in time.

There are no charges for the new features other than existing usage costs.
