Your Dedicated instances are physically isolated at the host hardware level from instances that belong to other AWS accounts. Dedicated instances may share hardware with other instances from the same AWS account that are not Dedicated instances. You can also use Dedicated Hosts to launch Amazon EC2 instances on physical servers that are dedicated for your use. Dedicated Hosts give you additional visibility and control over how instances are placed on a physical server, and you can reliably use the same physical server over time. As a result, Dedicated Hosts enable you to use your existing server-bound software licenses like Windows Server and address corporate compliance and regulatory requirements.

Savings Plans offer significant savings over On Demand, just like Reservations, but automatically reduce your bills on compute usage across any AWS region, even as usage changes. The table below lists the instance family and instance size configurations supported on Dedicated Hosts. The table also includes information on the number of instances you can run for a specific instance size and family based on the physical core capacity associated with the Dedicated Host.
