What is Fault Domain and Update Domain

Question

Accepted Answer

Fault Domain and Update Domain are concepts used in cloud computing to ensure high availability and minimize downtime.

Fault Domain: A group of hardware components that share a common power source and network switch. It helps to ensure that a single point of failure does not affect the entire system.
Update Domain: A group of virtual machines that are updated and rebooted together during planned maintenance. It helps to ensure that not all virtual machines are taken offline at the same time.
Both concepts are used in cloud services like Azure to distribute resources across different physical and logical boundaries for improved reliability and resilience.
