In this lesson, learn about the availability sets, Fault Domains, and Update Domains, and how these services affect your Azure implementation and protect your resources, ensuring your resources are always available.
- [Instructor] In Azure, just as we do on Premise,…we have to design for high availability and redundancy.…Availability sets provide redundancy…for your virtual machines and applications…by leveraging fault and update domains.…First, let's start off with the two reasons why…your virtual machine may be down or rebooted.…Typically, this is because of maintenance.…First, we have planned maintenance.…These are scheduled updates to your virtual machines.…In some cases, a reboot may occur…after those updates have been applied.…
Next, we have unplanned maintenance,…and this is typically due to a physical failure…at the data center itself.…In all likelihood,…a reboot will be occurring in this situation.…Let's take a look at the Azure fabric…and how these planned and unplanned failures can affect you.…In this very simple example,…all the machines in the fault domain…share a common power source or network switch.…I like to associate a fault domain to a rack.…If there is a failure in any of these fault domains,…then all the resources in that fault domain…
