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!!!
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!
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
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.
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?
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!
