What is a Load Balancer?

[@tarikcosovic783]

One of the clearest explanations I have ever watched, thanks so much!

[@ralfrolfen5504]

Best video about load balancer! No unnecessary stuff. Nice speed. Well speed-up-able

[@sajalhalder8831]

This is one of the cleanest explanation about load balancer!

[@meh398]

Thank you guys so much for your work! This video came out just at the perfect time for me. Great explaination as always!

[@IBMTechnology]

Perfect timing, then! 😎 👍 We're glad it was of use to you!

[@fsl001]

Well articulated. You must be a great teacher 👌

[@parmeshchidral3891]

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!

[@NasratullahEjaz]

Thank you so much for the provided information, we actually need a load balancer solution for our network environment and it is good to have your advice.

[@neail5466]

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✌️

[@sherardm]

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.

[@irisyan6491]

Definitely the best video on load balancers compared to any other!

[@barbobrien2097]

Best explanation by far.

[@intellectMind2024]

I had doubts about Citrix ADC as LB, this video gave a clear understanding . Thank You ❤️

[@mahirtaz3729]

It's amazing how knowledgeable and good explainer some of these IBM folks are!

[@anuragdesai9813]

[@anandkumar-ir8zj]

Wow 👌 such an awesome teacher 👏

[@alexschindler6766]

Thank you so kindly for your short but very informative video. Much appreciated.

[@rayblinks2me]

Thank you for dumbing it down! So easy to follow and understand. Can you discuss about security benefits as well?

[@mikebalaban3678]

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 ?.

[@iliasamine516]

❤❤❤❤ the best of the best ...thanks for ur explain

[@AnakinSkywalker-tg7yh]

It is a very good explanation of this topic !!

[@1NightInParisOfficial]

how did you guys get the transparent glass board to show no light reflections or glare?

[@NK-iw6rq]

Excellent video and great explanation. The IBM team is stellar.

[@retrofutur1st]

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 😊

[@ehsantavakoli2418]

Thanks a lot for simple and comprehensive explanation .

[@antonstepbystep]

Guys thank you so much for your exact explanation

[@saurabhbhoite8775]

Thank you guys so much for your work! Great explaination nd video

[@dnyaneshtathode5511]

Awesome one. Both content and representation. ❤️

[@conwayniall]

Awesome! Could you create a vid to discuss the differences between L4 and L7 load balancing?

[@IBMTechnology]

Thank you for the suggestion, Niall! We'll see what we can do, stay tuned! 🙂

[@shababkarim5907]

This is such a good suggestion!!

[@mustafakucuk1338]

We supposed that one server can not handle 10000 clients, but how one load balancer can? Video is good btw:)

[@bradleyknapp2909]

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.

[@-Engineering01-]

​@@bradleyknapp2909 wow, i didn't think that way thanks !

[@randomizerkid]

Clear explanation

[@chanaka7518]

Amazing video

[@shbakaien25]

Load Balancers are more badass than I thought

[@muradquliyev6448]

Good explanation. Thanks!

[@dmitrybabik8964]

Thanks for the interesting video

[@IBMTechnology]

You're welcome, glad you enjoyed it! 🙏

[@CodeWithPaulIo]

This was so good! Thanks!

[@anshumanbhattacharya6134]

thank you for the explanation. It's really awesome :)

[@6sense651]

Note to self: Round Robin Algo is inefficient, if theres 3 server and each server has 3 users... server2 and server3 users is done using the app while server1 users are still using it, server2 and server3 is vacant (which should not be)

[@jay2004r]

another great video!!

[@stefanvitoria5610]

Great video and content. By the way, how to reach you for advice for designing one?

[@patty-hv9jj]

[@ericksasonet]

Wonderful explanation!

[@andygerard228]

Thanks, that was simple to understand.

[@muhammaddevanozaidan6837]

such wonderful content, thank you for your effort

[@jasonkingnicetomeetyou8620]

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

[@kanikamaheshwari9732]

Very well & clearly explained. Thank You...

[@DennisTang-jt5wl]

Thank you, very useful

[@gunnerandersen4634]

Awesome, but Using DB clusters might not be that rare in case you actually need the use of a LB right?

[@Abhijit-techie]

how to reach the application through load bvalancer? one public ip of load balancer will be provided?

[@Mohammed-od4ju]

Great explaination! Thanks

[@WhiteSiroi]

nice, thank you, very helpful

[@michaelliu7729]

Well presented, thanks

[@4AlexeyR]

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.

[@Most_liked_videos]

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

[@callowindia]

Brandley your amazing

[@germancalderon1672]

thank you so much for the information!!

[@HimanshuSingh-ek3mu]

I love the way you explain thinks

[@SwapnadeepMukherjee]

Good for beginners.

[@camaro98xd]

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.

[@taalib_102]

Amazing! Very well explained.

[@r-nanovarusex4244]

Thank you man

[@manuk2803]

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?

[@paulantohe3783]

Thank you mister

[@josephchinemeremjerry3167]

Thanks for this information

[@nihhastlkinshit904]

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?

[@Michael-zb9h]

how to get in touch with you to get the best algorithm?

[@alphaman3765]

really awesome leachure

[@AndriiKSK]

nice video

[@haacki4720]

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?

[@treedents839]

can a load balancer become overloaded?

[@jonkidd9406]

Thank you!!

[@imamulhuda6202]

AWESOME. Thanks a lot

[@snake1625b]

Great video. So which service handles replicating the service amongst multiple servers?

[@hemachand5617]

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

[@jorisherry]

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...

[@yassinebouchoucha]

so what's the difference between load balancer and a hypervisor (both in software and hardware part)?

[@ahoussimea7164]

What about database load?

[@SirMrDany]

Could you do something about how to do database loadbalancing too?

[@JohnMayo-e5k]

I know I’m very late to this video but can you please explain how random is above round robin in this situation. They’re both similarly uninformed of the situation of the servers and just do their own thing, I would imagine they’d be equally unhelpful though if anything, at least round robin places it at a server only if it’s been the least recently troubled one, so there’s some minimal help there. I’m surprised random is considered between dumb and smart…

[@alejandrocano88]

great video, !!!!1

[@satyajitsethy657]

Could you provide some tutorials where session affinity/sticikess to be handles through GSLB/Load Balancer ?
