👉 Fault domains define the group of virtual machines that share a common power source and network switch.
👉 Each and every fault domain contains some racks and each rack contains virtual machine.
👉 Each of these Fault domain shares a power supply and a network switch.
👉 If there is a failure in the fault domain then all the resources in the fault domain become unavailable.
👉 You should place your vms such a way that each fault domain get one web server, one database server and like that.

📌 𝐔𝐩𝐝𝐚𝐭𝐞 𝐃𝐨𝐦𝐚𝐢𝐧

👉 Virtual machines get update domains automatically once they are put inside availability set.
👉 All virtual machines within that update domain will reboot together.
👉 Update domains are used for patching of the virtual machines.
👉 Only one update domain would be updated at the time
