Load balancing is critical to the maintenance of any highly demand digital experiences, website, application, databases, other compute resources. Proper utilization of a load balancer can prevent application failure, improve performance and availability by disturbing traffic.
In this lightboard video, Bradley Knapp with IBM explains how load balancers work and some different traffic distribution model options.

Best video about load balancer! No unnecessary stuff. Nice speed. Well speed-up-able
One of the clearest explanations I have ever watched, thanks so much!
Thank you guys so much for your work! This video came out just at the perfect time for me. Great explaination as always!
Perfect timing, then! 😎 👍 We're glad it was of use to you!
This is one of the cleanest explanation about load balancer!
I had doubts about Citrix ADC as LB, this video gave a clear understanding . Thank You ❤️
Well articulated. You must be a great teacher 👌
Yes please, it's so intriguing to learn how the smarter ones works.
If possible please make some indepth content for us enthusiasts.
You people rock✌️
Thank you so kindly for your short but very informative video. Much appreciated.
This video was so helpful im currently studying for the AWS SAA exam and wanted to get my details on this concept and this video was perfectly constructed.
Definitely the best video on load balancers compared to any other!
Thanks a lot for simple and comprehensive explanation .
Thanks, that was simple to understand.
Thank you for dumbing it down! So easy to follow and understand. Can you discuss about security benefits as well?
Guys thank you so much for your exact explanation
Thank you very much. Great explanation.
Although, I know about the Load Balancer.
However, it was nice to hear a simple and concise explanation about it in this video. Thank you, sir!
Amazing! Very well explained.
Awesome one. Both content and representation. ❤️
Excellent video and great explanation. The IBM team is stellar.
Thank you guys so much for your work! Great explaination nd video
Wonderful explanation!
This was so good! Thanks!
Thank you, excellent video!!
Thanks for the vid! Interested in setting up a loan balancer on a cloud vm like Google, Azure or AWS will keep my eyes peeled for your videos thanks again 😊
Very well & clearly explained. Thank You...
thank you so much for the information!!
Best explanation by far.
Good explanation. Thanks!
Excellent Explanation

Thank you for making your content easy to understand and follow for beginners. Your channel and blog is my go-to for concept definitions.
We are so happy to hear this! 🙏 Thank you for being our subscriber, Chika! 😉
What subject matters would you like to see covered here, that we haven't yet?
@@IBMTechnology None for now, but I'll be sure to drop a comment for it, when I find one.
Thank you, very useful
another great video!!

I love the way you explain thinks
Wow 👌 such an awesome teacher 👏
Thank you man
Thanks for this information
Great video explanation!
It is a very good explanation of this topic !!
Well presented, thanks
AWESOME. Thanks a lot
Thanks mate!
Thank you clear explanation
Thank you mister
Thank you!!
Amazing video
Thank you!!!
❤❤❤❤ the best of the best ...thanks for ur explain
Great video! If you are reading this, have a great day!
Good for beginners.
Thank you
amazing videos
Really nice video. In my point of view, it could be pretty good to add labels to 1, 2 and 3 scenarios to better remember the classification. Also maybe good to explain why the random method could be fine according to math. It's not clear. Maybe the random method is not so simple and gets one of the servers which is loaded less than the average? :-) Absolute random approach is worse than rolling-robin in my vision.
gosh i hope this one helps me wrap my head around it i been trying to figure out the best way to setup my vcn for like a week and just cant understand it all
So clear
Thanks for the interesting video
You're welcome, glad you enjoyed it! 🙏
great video, !!!!1
really awesome leachure
We supposed that one server can not handle 10000 clients, but how one load balancer can? Video is good btw:)
Mustafa, the idea of a load balancer is that its only purpose is to distribute the number of active sessions among N number of servers that are supporting the workload for X number of clients.
The load balancer itself is only used at the beginning of the session, it's not a constant intermediary point - its job is to assign the session to the least active backend server, and then to await the next session that needs to be instantiated.
Now, that said, it is always best practice to size your load balancer deployment the same way that you would size your server deployment - you will need much higher performance for load balancers that can expect 5,000 simultaneous instantiations than you would for a workload that would only ever see 500 instantiations, for example.
@@bradleyknapp2909 wow, i didn't think that way thanks !
Brandley your amazing
Thank you for the info! My fiance and I have issues with one another dropping out while playing video games. We have a good router that we are hardwired to and our pc setups are side by side. Would this be a solution to help with the dropping out? Is so what balancer would you recommend for this problem?
Awesome! Could you create a vid to discuss the differences between L4 and L7 load balancing?
Thank you for the suggestion, Niall! We'll see what we can do, stay tuned! 🙂
This is such a good suggestion!!
Better explained than Google Cloud, lmao.
Perfect
wonderful
how did you guys get the transparent glass board to show no light reflections or glare?
nice video
Thanks for explanation really simple to understand.
You're welcome, thanks for watching! 🙂
Super Easy explanation thank you...!
I have 1 question which I didn't understand completely about ( round robin ) why or how it will be unbalanced if someone entered for 2 min the other for 2 hours ?.
IBM, will you make a video specifically discussing load balancing providers? I see cloudfare used a lot when certain site mirrors time out or thow a network exception and expose the error message and host information ? This is not usually on clearnet.
THX
cool thanks
so what's the difference between load balancer and a hypervisor (both in software and hardware part)?
Great video and content. By the way, how to reach you for advice for designing one?
what actually does a load balancer contain(hardware POV)?
is it a server itself or just a program to select the server according to the algorithm?
How does load balance work with 2 differen nat types one being Nat type 3 while the other one can be either Nat type 1 or 2? AT&T is carrier grade nat type 3.
Hi, thank you for the video. I have two questions.
If load balancer single computer, so it really can process millions of requests at once, like on google, twitter websites? (Maybe there is more info?)
And the second one, we have lots of application servers, but database is only one, how to handle this, database can handle millions requests at once?
how does social media platforms manage their load balancer considering geo time of user logging in n using their apps. which type of technique they use?
locality based (geographic) or affinity
Great video. So which service handles replicating the service amongst multiple servers?
Load Balancers are more badass than I thought
Could you do something about how to do database loadbalancing too?
Could you explain load balancing with SSL?
Could you provide some tutorials where session affinity/sticikess to be handles through GSLB/Load Balancer ?
Thanks for the suggestion, Satyajit! We'll see what we can do!
Awesome, but Using DB clusters might not be that rare in case you actually need the use of a LB right?
Load balancing the millions of requests to the app servers are just great but what about the common database that the app servers are talking to ? Can't it be way overloaded with those million requests hitting that database or is it the autoscaling applies to db also
It's a whole topic on it's own. Data can be stored on different servers so not application server access the same database server. Data that is accessed often can be put on a more performant server or replicated to multiple servers...
What you use application of pen and invisible whiteboard?
Hey there! Maybe these behind the scenes would answer your question 👉 ibm.co/3BTyPxE 😉
What's the benefits of IBM cloud vs Azure?
The depth and inspiration of this content are motivating. A book I read with related messages altered my life's course. "A Life Unplugged: Reclaiming Reality in a Digital Age" by Theodore Blaze
How does this transparent board work ??
Search on "lightboard videos".
How do you access a load balancer
Hi Bill! IBM Cloud offers several load balancing solutions, you can check them out here 👉 ibm.co/3n3Rz7l
Additionally, a variety of open source load balancers are available, each with different functionality and server compatibility: Neutrino, Gobetween, LoadMaster by Kemp, and the Linux-based Seesaw. LoadMaster and Neutrino offer free versions and fee-based commercial versions with added functionality. If you’re considering open source, be sure to review functionality and compatibility with your specific server first. 🙂
can a load balancer become overloaded?
what if the load balancer itself gets overwhelmed?
So which algorithm is the best anyway?
Y’all are literally creating the “ Matrix “.
i think third one is for no use isn't that?
