Azure dedicated hosts are single-tenant dedicated servers. They cost more than the multi-tenant Azure VMs most organizations are accustomed to buying. So why pay more for an Azure dedicated host?
The two biggest reasons are control and compliance. Azure dedicated hosts give you greater control for more visibility, faster support Time to Resolution (TTR), and the ability to build a private cloud on Azure. In addition, for regulated industries such Financial and Healthcare, the hardware isolation of an Azure dedicated server ensures compliance and is worth the premium.

Azure dedicated hosts give you more control for increased visibility at the hardware level, faster Time to Resolution (TTR), and the ability to build a private cloud on Azure.
You receive hardware isolation at the physical server level so that only your organization’s VMs are placed on the host.
Since you have access to the dedicated host, your IT team or third-party Microsoft support provider can troubleshoot issues faster. A lower support Time To Resolution (TTR) yields more uptime for your VMs and enterprise.
Hardware isolation means your Azure VMs are isolated like your own servers in your data centers. The additional layer of security allows enterprises to build their own private cloud on Azure with all the benefits of IaaS or PaaS.
Multi-tenant Azure VMs are by their very nature, less secure than single-tenant Azure dedicated hosts. Organizations should invest in Azure dedicated servers where the private cloud benefits of stronger security and compliance are necessary.
Azure dedicated hosts reduce risk because server resources are not shared by multiple organizations. In a single-tenant Azure private cloud, another organization’s Azure VM security incident will not impact your enterprise. Nor will they be able to impact the performance of your VMs with high IO or memory usage.
This reduction in risk is particularly acute in highly regulated industries like healthcare and finance. The healthcare industry must meet HIPAA requirements when dealing with patient information. As a result, each hospital or healthcare provider needs its own data center or private cloud to ensure compliance. The financial industry has similar responsibilities around PII and banking information.
