In some scenarios, DDH enables you to deploy your business flexibly, guarantee business safety and compliance, and reduce the cloud migration cost.
DDHs are ideal for the following scenarios:
- BYOL (Bring-Your-Own-License)
If you have your own per-socket, per-core, or per-VM software licenses, you can use these licenses on a DDH the same way you use them on a physical server, subject to your license terms. DDHs can lower the costs while migrating your business to cloud. The licenses involved include, but are not limited to Microsoft Windows Server, Microsoft SQL Server or other software licenses.
- Strict regulatory and compliance requirements
DDHs are ideal for the businesses that require strict regulatory compliance, because you can have the full control over the resources of the physical servers, which enables physical isolation on physical server level. Besides, you can create ECS instances on a specified DDH, which meets the regulatory requirements for your business running environment.
- Performance stability sensitive
Some businesses, such as those in the gaming industry, require higher computing capability and stability of the servers. DDHs guarantee the stability of the CPU and the I/O, assuring the performance of your business.
- Deployment flexibility
You can specify a DDH to create ECS instances, migrate an ECS instance between DDHs or from shared cloud hosting to your DDH. Flexible deployment improves your orchestration ability of applications.
