We are excited to announce a new Amazon Virtual Private Cloud (Amazon VPC) concept — the Dedicated Instance. Dedicated Instances are Amazon EC2 instances launched within your VPC that run hardware dedicated to a single customer. Dedicated Instances let you take full advantage of the benefits of Amazon VPC and the AWS cloud – on-demand elastic provisioning, pay only for what you use, and a private, isolated virtual network, all while ensuring that your Amazon EC2 compute instances will be isolated at the hardware level.
You can easily create a VPC that contains dedicated instances only, providing physical isolation for all Amazon EC2 compute instances launched into that VPC, or you can choose to mix both dedicated instances and non-dedicated instances within the same VPC based on application-specific requirements.
