Fault Domains, Update Domains and Availability Set In Azure Virtual Machine
In this article I will talk about Availabilty Set with Fault Domains and Update Domains Availability Set: Availability Sets ensure that the Azure virtual machines are deployed across multiple isolated hardware nodes in a cluster. By deploying your vms across multiple hardware nodes Azure ensures that if hardware or software failure happens within Azure, only a sub-set of your virtual machines are impacted and your overall solution is safe and in working condition. Availability set provides redundancy for your virtual machines. Availability set spreads your virtual machines across multiple fault domains and update domains. If you want to leverage Microsoft’s 99.95% SLA from Microsoft you must place your VMs inside availability set except your VMs are having premium storage. Following are the 3 main scenarios which can cause your vms in Azure: Unplanned Hardware Maintainance Events - When Azure platform predicts that the hardware or any platform components associated to a phy...
