We are pleased to announce AWS CloudFormation support for Amazon Virtual Private Cloud (Amazon VPC). AWS CloudFormation allows you to easily provision, manage and update a collection of related AWS resources. With Amazon VPC, you can now define a virtual network topology using a CloudFormation template and customize the network configuration to closely resemble a traditional network that you might operate in your own datacenter.
All resource types such as Amazon EC2 instances, security groups and Elastic IP addresses, Elastic Load Balancers, Auto Scaling Groups and Amazon RDS Database instances can now be deployed into any existing Amazon VPC using CloudFormation templates. The templates allow you to run multi-tier web applications and corporate applications in a private network. With Amazon VPC and CloudFormation, you can easily control which resources you want to expose publicly and which ones should be private.
