Hello, For build VM avaiability set we must create at least 2 VMs for each application, right? I just want to know if there are 2 VM identical for each app, will both VM replicated each other automatically by Azure? I mean if i do some changes on the app or the OS, should i do exact same changes on another VM?

    Hi,

    Yes, for more resilience to failure you would need at least 2 VMs for the workload/application when using Availability Sets.

    No, the VMs will not replicate changes to each other automatically. The apps/workloads running inside of the VMs need to be designed to replicate/sync/share data between each other, -OR- the apps/workloads need to be stateless.

    Hi @Handian Sudianto ,

    ... will both VM replicated each other automatically by Azure?

    No, there is no automatically sync between the 2 VMs.

    ... should i do exact same changes on another VM?

    Yes, that's the best option. But you have to do this manually.
