got my az-104 last week, your videos are the best azure resource that is out there. keep up the magnificent work you're doing
Congrats and thank you
no bs, no bluffing he really knows his stuff.
Thanks John. Really appreciate your time and effort in producing these videos.
Great informative video, John! Keep doing these! Thanks!
Thanks indeed John, useful again video!!
Another great video John! Thank you for your contributions to the community! We appreciate it bud!
Thank you!
thanks John for making these high quality videos! whole community should be thankful!
Generic comment to show my appreciation. Keep winning John!
Thank you John , was having some challenges grasping this Availability Zone concept, this is a great help.
Thank you for this rich extremely-beneficial content; I know it takes a lot of prep work to put all this together
Glad you enjoy it!
Nice video. Working as an IT expert in government "fire / medic". It explains a load balancer, gateways ... perfectly. Keep it up.
That was crystal clear and so well explained, thank-you for sharing your knowledge and helping so many level up!
Very welcome
Excellent video as usual, lots of very helpful details. Thanks
Great video. A tricky concept well explained. Thanks for producing and posting.
Glad you enjoyed it!
Thanks John, really great training material.
I always thought AZ represent a physical datacenter. Thanks John for the details and helped clarify a lot of questions i had about AZ .
Fantastic material on your channel John, thank you so so much! People like you make this world a better place! Really useful for my new job! Also I see how you've improved audio etc in the newer videos vs the old. Seems post-tattoo videos are better quality :D
My pleasure!
best video i've ever seen on availability zones. The visual of the subscriptions and how resources could be dispersed in a given region and the zones; well done! I've failed AZ104 twice now and you sir are heavily recommended online and can't believe I didn't hear about you before my first failed attempts!!!
Very kind, thank you. I have a whole playlist around 104 and a study cram. Keep at it, you'll crush it next time.
Thanks John, very helpful!
thanks John! super interesting this video :)
Yes it's very interesting to me that VNETs and subnets in Azure can span all AZs in a given Region, whereas in AWS, a subnet in a VPC can only exist in 1 AZ at a time. Good video!
Yeah, as I was watching this I was thinking the same. I could have sworn that AWS VPC subnets cannot extend to other AZ's. Thanks for clarifying!
This was helpful, thank you!
Great explanation,Thanks
Thank you for an amazing video.
Best AZ explanation available on the internet
Thanks a lot, John!
Great video by John
Thanks a lot
Thanks!
Excellent explanation, thanks
Glad you liked it
Very helpful. Writing here because of the YT algorithm. ;)
Hehe thanks!
Thanks John.
great content
John, as using Zone Redundancy improves resiliance when one has multiple eggs in multiple baskets does the service SLA change? I'm trying to discover the zone redundant SLAs for a number of supported services without success.
The SLA documents show where SLA is different if AZs impact.
Do You have a video discussing Azure AZs, App services and HA? Is it possible to have App service plan with 2 hosts spread between 2 Azure AZs. Thanks!
Anything I have is on the channel. Just search.
For the algorithm! 😁
How come if you don't choose an AZ, the disk always matches the VM? The disk and VM go somewhere, and even if the disk is LRS, when you create a VM, it matches the disk, and it certainly is in some portion of the hardware belonging to a zone. Does the disk dictate which zone it is, in the background?
Same goes for data disks. You can attach a data disk to any VM zoneless VM. Are they all always in the same "invisible" zone?
If you don’t pick an az it just gets placed in some cluster in the region and managed disks will align to same Datacenter.
An availability set gives guarantees on update domains, is this also the case for availability zones?
Think of an az as a merge of update domain and fault domain so yes across the 3 azs
So, Availability Sets are to racks, as Availability Zones are to datacentres. Is that right??
pretty much you can think of it that way.
