Dedicated Hosts & Host Groups in Azure

Dedicated Hosts:

Azure dedicated hosts provides physical servers that host one or more Azure virtual machines. Your server is dedicated to your organisation and workloads capacity is not shared with other customers; this host level isolation helps address compliance requirements. As you provision The Host you gain visibility into the server infrastructure and you determine the host’s maintenance policies.

Host Groups:

• Host group is a resource that represents a collection of dedicated hosts. you create a host group in a region and an availability zone, and add host to it
• Host is a resource map to a physical server in Azure data centre 
• Each host can host multiple VM’S, they should be of the same size series. 
• Host group is created in one availability zone
