Avoid these Mistakes with Azure Availability Zones and Availability Sets!

In this video we review Availability Sets including fault domains and update domains. Then we look at Availability Zones. After that we review Azure SLA’s for VMs deployed with Availability Sets and Availability Zones. Once we understand these concepts, we look at two mistakes to avoid when deploying highly available solutions with Availability Sets and Availability Zones.

Thanks Travis for creating very informative video, Please start some Azure Migration series also .

Amazing bro🤩

Let’s say there are three availability zones(1,2,3) in a region. If we do not specify them, the zones have “None” on it. If we specify [1,2,3] is that equivalent to None and we’re leaving it up to Azure to decide where it wants to place the resources?

Hi Travis, if I want to spin up 6 servers. I will choose 3 az option, 2 vm in each zone. Will the 2 vm be spinned up in availability set too?

[@Ciraltos]

An availability zone is one or more datacenter, so the 2 VM's may be in different datacenters. I can't find the source, but I did see that scenario address is the Microsoft documentation on availability zones, availability sets are not needed to maintain the higher SLA.

Hi Travis ! Your videos are awesome

Hi, Travis. I need some help with hyper-v and installing a https certificate for a website. .
As a favor, could you get ahold of me?

[@jennisonb37]

At 2:35 you mention that a web sever deployed to 3 zones would survive a single datacenter outage. Wouldn't it survive 2 datacenter outages as you would still have the 3rd available?

[@Ciraltos]

Yes, in theory it would. There are other considerations like provisioning enough capacity to handle an increased workload and load balancing to route traffic to the remaining web server, but it would be available.

@@CiraltosThank you for responding, Travis. I do understand the 2 or 1 remaining zones could potentially suffer performance if they had to cover the load for the down one(s). Thanks for clarifying.
