Dedicated Hosts
Dedicated Host is a physical EC2 server with instance capacity fully dedicated for your use. Dedicated Hosts can help you reduce costs by allowing you to use your existing server-bound software licenses, including Windows Server, SQL Server, and SUSE Linux Enterprise Server (subject to your license terms), and can also help you meet compliance requirements.
Dedicated Hosts benefits:
- Save Money on Licensing Costs: Dedicated Hosts can enable you to save money by using your own per-socket or per-core software licenses in Amazon EC2.
- Help Meet Compliance and Regulatory Requirements: Dedicated Hosts allow you to place your instances in a VPC on a specific, physical server. This enables you to deploy instances using configurations that help address corporate compliance and regulatory requirements
