Hey Adam, The content you create is of super high quality with each and everything explained in detailed manner. Your videos are one stop solution for me for any Azure related stuff. Please keep spreading the knowledge.
Just an observation for a comment you made at 4:04: you state that machines are updated automatically with Scale Set. I just wanted to note that there's actually 3 update policies with VMSS: Automatic, Manual & Rolling. Thanks
Yea, I meant that the entire process of updating OS is automatic. You are correct on policies which provide you certain degree of control over this automated OS update process. Thanks!
I would say i have seen one of the best video of explaining in TH-cam.Kudos to you i am a beginner with Azure and i will follow more of your videos. and i could able to grasp the the terminologies and explanation of each and every term and the functionality of the load balancer and kudos to you i have subscribed your channel and thanks for the great video
HI, Suppose a web application used a sticky session (aka "session affinity") and use session for data holding purpose. Can we deploy this kind web application to VM scale sets as backed pool to an AG and use as URLs filtering purpose? If not possible then what is alternative solutions? Thanks,
Remember to have external service for session persistency like Redis because with VMSS servers will go up and down which will kill sessions even with session affinity. AG or FD in front is always advised for public facing apps :)
Hi. You mean common scale set tasks? If you here are examples docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-manage-cli
You can use CTRL + F5 in this example. It's quite useful when you need to reload tab and cache at the same time to see request going to the different instances.
Thnks Adam! i want to understand in which cases we use a combination of AG + Load balance and when we use only load balance ( public facing) if we have a web app hosted in App service (ASE) in Azure. Does the web app determine it ? ( AG - https , LB for TCP is am aware ). Few architect diagrams have them in combinations and some standalone with web apps on Azure..Any guidance is appreciated. ! ( Merry Christmas - you are doing a fab job by sharing your knowledge with the community - Thank you 4 that )
There is a cool guide for choosing appropriate load balancing option in Azure, check it out docs.microsoft.com/en-us/azure/architecture/guide/technology-choices/load-balancing-overview?WT.mc_id=AZ-MVP-5003556 thanks and merry christmas!
Hey Adam, The content is super and explained in detail By any chance, will you be doing AZ-500, SC-200, and SC-100 Training. If not, could you please suggest a few learning tutorials which you have reviewed.
hey Adam. In my scenario i have two identical servers (having two different private IPs of course) and sophos XG sitting top of the servers. In XG the way i loadbalanced is that pushing traffic on both servers and it distributes the traffic. Since azure does not have a public dns url, which means i should be directing my application to the public IP only?
I have seen these 02 options under Load balacer Rules option...I have gone through MS Docs but unable to understand these terms...If you could explain these 02 in simplest form with example.... would be much gr8ful.
Hi Adam, Thank you for explaining things so clearly. I am facing an issue. When I am doing curl localhost -usebasicparsing, it is giving me 'Unable to connect to the remote server'. and so, my loadbalancer is also not working properly. Any idea what can be the issue here?
Hey! That's weird. Did you use the script that I provided for this tutorial? If so, maybe check if VMs got extension installed successfully.Thanks for watching :)
ปีที่แล้ว
great video, Do you know how to install ssl certificates to loadbalancer?
Hey Adam, Thanks for putting up this. Really appreciated. One request, will you be able to do a series on APIM? specially Policies and Azure as function of APIM backend? Cheers
Hey Adam, could you please let me know if I can use Azure load balancer (L4) to load balance 2 Web Apps (app service) deployed to different regions.? I know that we can use traffic manager, afd but not sure if Azure load balancer
Hi mate, please check this guide on recommended options for load balancing solutions docs.microsoft.com/en-us/azure/architecture/guide/technology-choices/load-balancing-overview?WT.mc_id=AZ-MVP-5003556
Hi Adam, the demo you had seems to be for L4 Load Balancer. Would it support a web application running in the backend pool listening on HTTP protocol (REST API)? Also, when would you use L7 Load Balancer?
Hi Adam, You have been posting amazing videos and thanks for that. Could you please explain about how the traffic will flow to public load balancer when we have firewall placed in front of it. Lets say we have web application hosted internally and its load balanced using public facing load balancer. But I want the internet traffic to first hit the firewall before its sent internally. Where should the public DNS point to? My Firewall Public IP or Load balancer PIP? If its to my firewall, how that will be routed to my load balancer.
So how would I configure Each VM to be a duplicate of each other? I assume I would have to have my code replicated to each VM...how would I handle this automatically?
You need to create virtual machine image. If you are building from code then you can build image in tools like DevOps, etc. There are few blogs and Microsoft doc entries on this so feel free to check around.
Hi Adam.. This is regarding balancing multi-tier applications by using both public and internal Load Balancer, how to route traffic from public load balancer to internal load balancer
Check this out docs.microsoft.com/en-us/azure/architecture/reference-architectures/n-tier/n-tier-sql-server?WT.mc_id=AZ-MVP-5003556 in general you LB isn't connected to another LB, it's the application to connect them
Thanks Adam for such informative video. Can one load balancer handle millions of requests? How Facebook, Amazon etc handles the user traffic? Do they have single load balancer? If I am in India and Load balancer is in USA so does it mean my request will go USA Load balancer and then to actual server for processing? Kindly explain.
It can handle millions of request if you configure it properly. Azure LB can't do cross region, so if your LB is in US then your server is also in US. Microsoft released some time ago cross-region load balancer docs.microsoft.com/en-us/azure/load-balancer/cross-region-overview?WT.mc_id=AZ-MVP-5003556
@@AdamMarczakYT Thanks Adam. So does it mean for Facebook/Amazon kind website we need only Single LB? In case if multiple LB is also an possible then how DNS will manage it?
Best way to learn Azure is to play around with it. Try creating internal LB with one VM and nslookuping it :) It only takes 15 minutes and is the best way to learn. Highly recommend it.
Hi Adam, Nice Tutorial. but why did you use a Availability set instead of a Scale set.. With an Availability set you need failovers to demonstrate, but with a scale set you can give up a minimum of 3 and there is a round robin sceduling. Or is there another reason for your choice? then another question. In your introduction you also spoke about outbounding rules. But I can not figger out how to set them on this load balancer?
Great question Leon. I did it mostly for didactic purposes. If I chose the scale set then load balancer is automatically created and configured. I wanted to show how easy it is to create and configure one yourself too. Here is the tutorial on outbound connectivity configuration docs.microsoft.com/en-us/azure/load-balancer/outbound-rules?WT.mc_id=AZ-MVP-5003556 :)
Thank God !!! I wasted almost 2 days to find the option under back end pool ->Associated to "Availability Set" and this option is was there in old demo videos :) and finally I verified that your demo was also showing "Virtual machine" and Virtual Machine Scale set" :) Microsoft keep on changing the options :) R&D :)
HI Adam , follwoing all your videos , very helpful in learning Azure. I am looking for some stuff that could explain how Azure Load Balancer interacts with Ingress controllers in AKS cluster. Specifically how it manages to separate/forward request for different namespaces in a cluster.
Application Gateway is surely on the list. For now check MS guide on differences and choices docs.microsoft.com/en-us/azure/architecture/guide/technology-choices/load-balancing-overview

Hey. Azure Load Balancer can have public DNS if it has public IP assigned. Go to your public IP configuration blade and set DNS name there.
Too good, superb explanation :-)
