Dedicated Instances are Amazon EC2 instances that run on single-tenant hardware dedicated to a single customer. They are ideal for workloads where corporate policies or industry regulations require that your EC2 instances be physically isolated at the host hardware level from instances that belong to other customers. Dedicated Instances let you take full advantage of the benefits of the AWS cloud – on-demand elastic provisioning, pay only for what you use, all while ensuring that your Amazon EC2 compute instances are isolated at the hardware level.
