    For the question below, now I understand we need 3 Host groups as host groups are Zonal.

    However from the video in the link , it says VMSS can be deputed across Zones on different dedicated hosts.


    Agila plans to implement the following modifications for their migration to Azure:

    <ul data-indent-level=”1″>

  • Migrate AVES-APP to Azure Virtual Machines and use Azure Dedicated Hosts.

  • Migrate external storage used by AVES-APP to an Azure Storage Account.

  • Migrate DB1 and DB2 to an Azure Database Service.

  • The business requirement for these changes must be to reduce costs and administrative tasks.

    Hi Venkata,

    You are correct when you said that a virtual machine scale set can be deployed across multiple availability zones.

    But a host group can only be deployed to a single availability zone. Since you need to achieve high availability, you need to create one host group per availability zone. The host group and the scale set must be using the same availability zone.

    Since you need three host groups, you need to deploy 3 VMSS as well. One for each host group.

    Please let me know if you have any further questions.

    Thank you.
