Reserving the entire host provides the following benefits:
Hardware isolation at the physical server level. No other VMs will be placed on your hosts. Dedicated hosts are deployed in the same data centers and share the same network and underlying storage infrastructure as other, non-isolated hosts.
Control over support events initiated by the Azure platform. While the majority of support events have little to no impact on your virtual machines, there are some sensitive workloads where each second of pause can have an impact. With Azure Dedicated hosts, you can opt in to a support window to reduce the impact to your service.
Simplify the deployment of business-critical applications in a single-tenant environment. Increase control and scalability, without limiting your options. Deploy Windows, Linux, and SQL Server virtual machines on Azure. Select the server and CPU type, number of cores, and additional features. The underlying hosts you provision are single-tenant and dedicated to your Azure VMs and workloads. You determine the timing of all platform-initiated maintenance operations, such as OS patching, or hardware or software restarts. Select Azure VM sizes and operating systems on the same host.
Comply with corporate policies and industry-specific standards by taking advantage of the certifications Azure offers. Place your Azure VMs on a dedicated hosting server that runs only your organization’s workloads to meet corporate compliance guidelines and standards. Get insights on the underlying cores to meet server-based software licensing requirements.
With the Azure hybrid benefit, you can bring your own licenses for Windows and SQL Server to Azure. Using the hybrid benefits provides you with additional benefits.
