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:. Allows you to consistently deploy your instances to the same physical server over time. Provides additional visibility and control over how instances are placed on a physical server. For more information, see Host recovery. Dedicated Hosts allow you to use your existing per-socket, per-core, or per-VM software licenses.
Differences between Dedicated Hosts and Dedicated Instances
Many businesses migrate to the cloud via Amazon EC2 for scalable, redundant, on-demand cloud computing and data storage. With the traditional cloud computing model, many users often share space on the same server that is hosted by a cloud computing service company. Many businesses are hesitant to move to the cloud for fear that a glitch in a firewall or a savvy cyber-criminal could somehow cause the data to leak into the cloud servers of other organizations hosted on the same physical server by the cloud company. The options share similarities in that both provide clients with instances in the cloud that run on dedicated physical hardware. As the end-user has complete control over which physical server they are running their instance on, they can transfer their software licenses held in-house over to the cloud in a similar manner to which licenses are transferred during physical hardware upgrades. Not having to purchase new software licenses coupled with the cost savings of the cloud can lead up to significant savings over time. With an Amazon EC2 Dedicated Host, users are charged per host not by per instance This means that clients are billed regularly for services instead of being billed by instance usage.
How to manage EC2 Dedicated Hosts using AWS License Manager
Dedicated Hosts can help you address compliance requirements and reduce costs by allowing you to use your existing server-bound software licenses. When you launch instances on a Dedicated Host, the instances run on a physical server that is dedicated for your use. While Dedicated instances also run on dedicated hardware, Dedicated Hosts provide further visibility and control by allowing you to place your instances on a specific, physical server. This enables you to deploy instances using configurations that help address corporate compliance and regulatory requirements.
