Excellent shirt! Reminds me of the time I spent working for Netscape back in the '90s.
The Shirt Gives me nightmares because as part of the IE team and MSFT, I had to deal with NSCP! :-). Not fun times.
Great content. Thank you John. BTW Legendary T-shirt 👍
Glad you like it!
Thanks, John, as well ways a great video. Love the concept of Layer 4 GLB! Looking fwd to your video on comparison amongst all the different offerings of LBs. That will be a great video to share with my friends who are learning Azure! Cheers and thanks once again.
enjoying this video for today learning, thanks a lot!
You are welcome!
Excellent content john. I am a big fan of your content and you are a great teacher in youtube explaining the azure services in detailed to all of us. Thank you!!!
Much appreciated!
Thanku thanku thanku.. this video cleared my doubts to a larger extent. I was just wondering this same question in my mind but had no proper answer. Your explantion is so nice it helped me get the idea like what actually happens is such cross region situation.. 😊
Great video. Looking forward to seeing Azure Front Door :-)
Thanks for the video. 😊
Excellent Explanation, Thx John
My pleasure. Thanks for watching
Excellent John! well explained
Thanks
Excellent as usual, you are the best
Very kind, thank you
Thank you John
Superb. Well explained and enjoyed watching it. Thanks John. Pls also make a video on Virtual WAN and AFD as well.
Noted
Nice content. Thanks John. Little off topic, when should one use Traffic Manager instead of Azure Front Door for Layer 7 global load balancing?
Watch the video I posted after this about picking a load balancing solution :-)
In continuation of my previous comment, what would be the best approach to simulate a HA test drill for GLB (besides making the SLB unhealthy) because you can never really simulate a regional failure unless that happens in reality? Typical Ops teams would want to do the drill in a frequency and this would even be required to be demonstrated to the clients with an outcome. I could do that in certain ways but what I am looking for is the best approach IYO.
I think the main way would be to shut down the backends in a region.
Hi John,
Thank you for the video. I do have some questions:
Same thing can be achieved through Traffic manager. What is the advantage of using Global LoadBalancer?
And Is there a way to restrict regional Load balancer to accept traffic onlyfrom Global LB??
i'm covering a comparison on Thursday. Traffic Manager is DNS based though so you have TTL issues etc.
Love watching these videos 😁, will there be a deep dive video on anything coming soon?
Lol don’t talk about future content :)

Great explanation as usual John! What happens if the closest region remains up and so does the SLB in that nearest region but the workload in the backend pool goes down - say both VM's in the regional SLB backend pool go down? I would presume that the GLB would consider both the health of the nearest regional SLB (means that backend is also healthy and available) and the region status, based on which it will/won't route to another region/SLB. I see in the documentation they refer to the term "healthy regional load balancer" without stressing on the fact that routing to the nearest region depends on both factors - health of the workload (determined by the health of the SLB) and the region availability as a whole.
If all backends are unavailable it would be considered non-healthy I believe and would not be routed. Try it :-)
@@NTFAQGuy Tried it and bang on - exactly happened the way you suggested :-)

Personally I like FrontDoor a lot , as it gives me WAF , Managed SSL certs etc .
The only pain I have been having with FrontDoor is that the Microsoft dosent give any guarantees on the FrontDoor Anycast Public IP , I guess this Global Load balancer solves that , but this again lacks not allowing us to add WAF or SSL ... Cuz this can just do Standard LB as back end and not even App GW's ... Bummer 😔
I'm posted an overview of all on Thursday :-)
Dude you certainly have some big guns on you...
Lol, camera adds 10 lbs 😃
Netscape 4.0 FTW
