What Is The Availability zone, Availability sets, and Region in Microsoft Azure
What are these? What level is the service level agreement that azure provides for your VM’s?
To know more, check this video by Author & Cloud Expert, Atul Kumar from k21Academy
Where he covers:
☛ What is the Region:
A region is a set of data centers deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network
☛ What is the Availability Zone?
Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more data centers equipped with independent power, cooling, and networking.
☛ What is Availability Set?
An Availability Set is a logical grouping capability for isolating VM resources from each other when they're deployed. Azure makes sure that the VMs you place within an Availability Set run across multiple physical servers, compute racks, storage units, and network switches. and More

Great explanation but you missed to explain update domains and why are they called so
Brother where you when I wrote AZ 104 the 1st time🥰
Great presentation, I've seen many videos but you describe materials much better. Many thanks.
Hey, thanks ! Keep watching and supporting!
Great explanation about availability zone and availability set. Thanks a lot 👍
Glad it was helpful!

Nice explanation vm -- fault domain within DC Aavaibility set -- fault tolerence another DC Avaibility zone--- multiple Avabillity zone - Region -- - Region Fault tolerance is Region pair --Geography / Area
Thanks for sharing
Very nice explanation.
Thanks, keep watching!
Thanks for lesson!
Thank you ! Keep supporting!
one query - if we create only one VM how does the availability set/zone matter as it will not be paired with any other VM. One VM placed anywhere will have no backup.. Am i missing something here..
Aditya More You are right just 1 VM won’t give HA and you’ll need at least 2 VMs - Atul
Thanks Atul.
I wanna ask you, I follow you more than 10 years now and my knowledge that you are ORACLE expert.... but currently you move to Microsoft technology.... can you advise on why ?
Hany Ghareb Thanks and wonderful question. I am not moving away from Oracle but adding Azure Cloud with my Oracle Cloud Knowledge. Knowing Cloud is good and everyone must know at least one Cloud but having multi Cloud skill is what will set one apart. We have customers who are using both Oracle & Azure Cloud and hence We are learning Azure with Oracle Cloud . Thanks for asking Atul
Can we say fault domain as availability set
Thanks Atul, i have one question, i have 2 vms, 1 with 8gb ram and other 1 with 4gb ram and configured availability set, if 8 GB vm running fault domain goes down, my other VM will run but with low performance right? and how long will take my 8gb to come up and running.
babukumarji yes you’ll be running with lower performance when other Node goes down. About 8gb machine to be back, it all depends on what was issue and how long it takes to fix issue . I hope that makes sense. Atul
Good explanation, very simple and sweet

Why Microsoft support only 3 fault domain, why not more than 3
Deepak Wanjale well good question but I don’t think Azure reveals reason but why you need more than 3 ? Chances of all 3 FD being unavailable at same time will be fairly low and if it does then you have AZ so 3 works and should be enough - Atul
Thanks Atul ...please help with answer for ==> If fault domain is 0 for 1 VM, does it means that the VM is not part of any Availability set ? I can understand Availability set as Group or logical group of Fault domain ( one or two Server rack with same power & networking) please correct if my understanding is wrong here ..
Awesome description and visuals - many thanks
Thankyou for the feedback
Thanks for the video, May I ask why Microsoft does not support VM creation with fault domains in a two datacenter in same availability zone
utp mahesh this is because FD is within server rack and server rack can’t physically be in two different DCs Atul
@@K21Academy Thank you sir for quick reply
Great experience. Thanks
Thanks,keep watching!
Hello Atul,
I have one question. I have seen Microsoft recommending creating 2 AD DC servers. What is the use of creating 2 servers while we are setting Availability set count to 2. What is the difference between this 2.
@Mahesh when you say 2 AD DC servers , are you talking about on-premise ? On Cloud, you’ll be deploying Azure AD. We create 2 servers and put them in same Availability Set so Azure will place these two servers in different fault domain . This is any normal windows or Linux severs running on Azure . Let me know if this is not clear. Atul
@@K21Academy I am talking about 2 AD DC on Azure. Moreover if we have 2 Availability set for 1 server then why we need 2 AD DC on azure.
Mahesh Ingale we are not saying 2 Availability set for 1 VM, it’s others way, 2 VMs in same Availability Set that will put these 2 VMs ( each assume running AD DC ) in 2 different fault domain .
If you want to protect failure at zonal level then you put these 2 VMs in separate Availability Zones. Atul
If the data is being hosted across 3 data centre’s, do we still need to set up DR ?
Very clear explanation, thank you..
Veni Sri Thanks and glad that you found it useful. Atul
Thank you for this video.
Much helpful !!
Glad it was helpful!
amazing explanation
Thanks, keep watching!
Superb sir, I was struggling to understand falut domain n after this video it's clear.. thanku so much
Glad to hear that
Thank you
Welcome!
Thanks it helped me a lot!
