Design for data center and fault domain redundancy

“

- [Instructor] Microsoft has several built-in features that we can leverage to protect our Azure virtual machines. But before we look at those options, let's explore the reasons why your virtual machine may be down or rebooted. And this is typically caused because of maintenance. We have planned maintenance, which is scheduled updates to the host systems, and this can result in a reboot. Next, we have unplanned maintenance and this is usually because of a physical failure at the data center. When this occurs, Microsoft migrates the virtual machine to a healthy host and a reboot will occur. Just as we do on premises, in Azure, we have to design for high availability and redundancy to mitigate against these failures. This can be achieved using availability zones, availability sets, which include fault and update domains, and paired regions. Let's start by exploring availability zones. Availability zones are unique locations…
