Which azure virtual machine feature staggers updates across vms based on their update domain and fault domain?

I'm Azure newbie and need some clarifications: When adding machines to Availability set, in order to prevent VM from rebooting, what's best strategy for VM's, put them in: -different update and fault domains -same update domain -same fault domain ? My logic is that it's enough to put them in diffrent update AND fault domain I used this as reference: Am i correct ? These update/fault domains are confusing My logic is that it's enough to put them in diffrent update AND fault domain You are right, we should put VMs in different update and fault domain. We put them in different update domain, when Azure hosts need update, Microsoft engineer will update one update domain, when it completed, update another update domain. In this way, our VMs will not reboot in the same time. we put them in different fault domain, when an Unexpected Downtime happened, VMs in that fault domain will reboot, other VMs will keep running, in this way, our application running on those VMs will keep health. To shot, add VMs to an availability set with different update domain and fault domain, that will get a high SLA, but not means one VM will not reboot. Hope that helps.

In my azure environment there are sets of virtual machines that are rebooting at the same time, I assume it has to do with auto-update settings. How do I turn off the auto-updates and enable manual scheduling for Azure Virtual Machine updates? When I go to the update blade it doesn't provide me any options. • You can surely disable the automatic updates for virtual machines in Azure by opting out of the ‘Automatic upgrades’ option in the Virtual machine’s ‘Operations’ section --> Update Management workspace as shown in the below snapshot. Same is the case for ‘Automatic updates’ for Guest OS and Host OS also because, if the ‘Update Management’ option is enabled, then an automation and a log analytics workspace account is created as shown below due to which the update management schedule for the Guest as well as Host OS is managed through the ‘Update Management’ section as the status of the VM’s update is reported in it through backend automation account and a log analytics workspace: - Thus, to disable the automatic updates for your VMs for the above option, i.e., through ‘Update Management’ feature, kindly refer to the below documentation link for details: - • Basically, when you provision a VM in Azure, at that time itself, you are asked the option for ‘Automatic by OS’ updates or ‘Manual’ updates in the ‘Patch Orchestration’ option under ‘Management’ section. At that time, if you select, ‘Automatic by OS’, then the updates for the VM are configured to be installed autom...

HOTSPOT - You have an Azure subscription that contains an Azure Availability Set named WEBPROD-AS-USE2 as shown in the following exhibit. You add 14 virtual machines to WEBPROD-AS-USE2. Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic. NOTE: Each correct selection is worth one point. Hot Area: Suggested Answer: Box 1: 2 - There are 10 update domains. The 14 VMs are shared across the 10 update domains so four update domains will have two VMs and six update domains will have one VM. Only one update domain is rebooted at a time. Therefore, a maximum of two VMs will be offline. Box 2: 7 - There are 2 fault domains. The 14 VMs are shared across the 2 fault domains, so 7 VMs in each fault domain. A rack failure will affect one fault domain so 7 VMs will be offline. Reference: https://docs.microsoft.com/en-us/azure/virtual-machines/windows/manage-availability Correct Answer: Box 1: 2 There are 10 update domains. The 14 VMs are shared across the 10 update domains, so 4 update domains will have 2 VMs and 6 update domains will have 1 VM. Only one update domain is rebooted at a time.

I'm new to Azure and have been struggling with a concept specifically update domains and fault domains. Probably having a harder time understanding Update Domains. So as I understand it, having 3 VMs in 3 fault domains would be essentially having those VMs spread out to three racks? Is that correct? Like this Fault domain 1 Fault domain 2 Fault domain 3 VM 1 VM 2 VM 3 If that is wrong, please correct me. So then what is an update domain? A lot of the documentation I have seen shows a demonstration for the fault domain similar to the table above and will describe what kind of sounds like the fault domain. If you have a link to a good explanation that would be a big help or if you think you could dumb it down for me a bit, that would work too. Each virtual machine in your availability set has an update domain and fault domain assigned. Fault domains indicate the group of virtual machines that share common power source and network switch limiting the impact of potential physical hardware failures, network outages, or power interruptions. Update domains indicate the group of virtual machines and underlying physical hardware that can be rebooted at the same time ensuring availability of some virtual machines during a planned maintenance. Link: If all the VMs in Fault domain go down at the same time, then there wont be any service down because the service requests are being handled by other replicas in other fault domains. So why cant we update all the machines in a single fault...
