Amazon Web Services has announced several updates to its Virtual Private Cloud service including a wizard for easier VPC creation, improved access controls and the ability to access VPC resources without a VPN connection.

"You can now create a network topology in the AWS cloud that closely resembles the one in your physical datacentre including public, private, and DMZ subnets. Instead of dealing with cables, routers, and switches you can design and instantiate your network programmatically," Amazon Web Services' Jeff Barr said in a blog post. "This means that you could store your entire network layout in abstract form, and then realise it on demand."

The VPC Wizard feature allows a VPC to be configured with four network architectures, ranging from a VPC purely accessed by virtual private network (VPN) to a VPC with a single public subnet.
