Amazon EC2 Dedicated Hosts allow you to use your eligible software licenses from vendors such as Microsoft and Oracle on Amazon EC2, so that you get the flexibility and cost effectiveness of using your own licenses, but with the resiliency, simplicity and elasticity of AWS. An Amazon EC2 Dedicated Host is a physical server fully dedicated for your use, so you can help address corporate compliance requirements. In License Manager, you can specify your licensing terms for governing license usage, as well as your Dedicated Host management preferences for host allocation and host capacity utilization. Once setup, AWS takes care of these administrative tasks on your behalf, so that you can seamlessly launch virtual machines instances on Dedicated Hosts just like you would launch an EC2 instance with AWS provided licenses. This helps you to save money by leveraging your existing investments. Learn more about your Windows licensing options. Some organizations need to run their instances on dedicated servers instead of multi-tenant servers.

The price for a Dedicated Host varies by instance family, region, and payment option. Regardless of the quantity or the size of instances that you choose to launch on a particular Dedicated Host you only pay for each active Dedicated Host. When you allocate a Dedicated Host for use, you pick an instance family such as R5 or M5 for the host. 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.

Differences between Dedicated Hosts and Dedicated Instances
Yet even with similar computational offerings, there are some major differences between Dedicated Instances and Dedicated Hosts. Here we explore some of the differences in-depth. Dedicated instances offer a few different options for paying for services. Users can pay on-demand for only what they use, without any long-term commitments. With Dedicated Instances you can pay per hour for compute capacity. This fee is only charged once per hour, instead of by the number of Dedicated Instances running.
For information about the configurations supported on Dedicated Hosts, see Dedicated Hosts Configuration. Dedicated Hosts and Dedicated Instances can both be used to launch Amazon EC2 instances onto physical servers that are dedicated for your use. There are no performance, security, or physical differences between Dedicated Instances and instances on Dedicated Hosts. However, there are some differences between the two. The following table highlights some of the key differences between Dedicated Hosts and Dedicated Instances:.
