Load Balancing | What are Load Balancers?

[@chayanchoudhury3042]

you are a Guru...if someone can explain a concept in 10 mins in a way as beautiful as this one...then hes called a GURU...

[@saritanegi8602]

Nice explanation especially about sticky session. Thank you

[@dominikseljan3043]

Awesome video! Just wanted to thank you for all these extremely useful videos about Spring and all the other stuff.

[@TechPrimers]

Thank you Dominik, Glad its useful for you all

[@shyam8722]

Fantastic Explanation. I am a non-technical / non-CS person doing a course on AWS and I didn't understand what load balancing was. But this video is amazing. Thank you so much!

[@techietejesh9811]

Concepts were neatly explained.thank you 😊

[@duaamouawad9479]

Very clear information

[@asifkamranmalick5313]

Short and sweet as always.

[@TechPrimers]

+ASIF KAMRAN MALICK thanks Asif

[@jamesodongo9981]

Thank you so much! Please, guide me on how I can do analysis of load balancing in software defined networking.

Anybody else's eyes see the round grey ghost dot between the Amazon Blue Squares at the beginning of this video?

i have deleted now , u can watch

[@aviT318]

In the Algo of IP Hash, Only desired IPs will go to desired host, but what about other non-desired or non-priority IPs, do they fall back to older "round robin" kind of Algorithm ? as it only give priority to desired IPs so what about non-desired IPs ? Could you please explain ? Thanks

[@nagautube1]

Thanks for the brief and clear explanations.

[@Amukina1991]

"it might take a while!" - jokes aside, this is really good man.

[@abbashittalamani9524]

It was superb 👍

[@shireen2296]

This a very helpful video - thank you!

[@andrzejokon1517]

As always great explained and another interesting subject. Thank you !

[@Kristofercodes]

Very very good video!! I took notes and watched it slowly and i learned a lot. Thank you very much :)

[@TechPrimers]

Glad it was useful

[@IndianCouple2022]

which load balancer we use mostly?

[@danni6113]

This is really good! Please keep up the awesome work!!!

[@AndreaNobili84]

This is so good !!! You clarify me a lot of stuff in an easy way !!!

[@kishankumargupta4200]

Also, can any load balancer use multiple algorithms to filter the best server to direct like it first uses the IP Hash and then least connection algorithm to get the server?

[@rupeshkamble9105]

Great video.. If we use sticking and suppose the requests are more than capacity of the handler then it will crash ..what could be possible solution for that, ?? I want it to be server or algorithm end. As I want to do research , application side code is not useful ( as Amazon is doing)

[@TechPrimers]

you can limit the number of requests by rejecting the new connections. You can either user load balancers like ngnix or do it in a custom fashion

[@prashantsingh-xr6zg]

So if I do nslookup load balancer , will it return the ip address of all the servers in the pool or load balancer also has it's own ip address?

[@KaranSingh-fo4bs]

Nice explanation.Keep up the good work !!

[@fluidityinmotion2452]

Nice one. Thanks team

[@iamdeepaksp]

How would one architect a platform with multiple servers and a single load balancer to handle multiple customer requests and server downtime?

[@TechPrimers]

There are different strategies to tackle them. For loadbalancing you can either use software loadbalancer (Apache. nginx etc) or hardware load balancer. You can configure health checks in load balancer to identify which server is down and which is not, based on which traffic is redirected.

[@MillionMania]

much help full bro..thank you

[@samirghanchi441]

Thanks for this Video it's really useful keep it up good work. :)

[@pareshdehadray7414]

If we use Sticky Session then what will happen if a server is crashed where request needs to go.

[@TechPrimers]

Load balancer decides that. It will either redirect to new instance or redirect to old(if load balancer did not know about the crashed insurance via keepalive health checks)

[@pareshdehadray7414]

@@TechPrimers Thanks for quick reply. If it will redirect to new instance then we will not get cached information on new instance. We use Sticky Session so that no need to use distributed cache so in this case new instance will not be useful. Is there any technique to handle this situation? Or should we avoid Sticky Session at all? If it will redirect to old instance then request will be error out.

[@AbhishekNigam]

You explain very well! Thanks a lot!!

[@malleshk2091]

Nice explanation! But I have one doubt. Is it not that load balancer itself will become bottle neck as all requests will come to it and it has to forward requests? How is this handled?

[@TechPrimers]

Hence there will be multiple instances of the LBs. If you have a global need, these LBs will have local and global instances

[@abhilashreddyintha8374]

Simply super

[@oron15]

Can you explain how to maintain session persistence in case of some server has fallen(when we are don't want to save cache) ?

[@ishwarsolanki4820]

Sir you have content below topics Link Load Balancer between two leased line

[@Waooo7409]

Nicely explained. Plss carry on

[@pareshdehadray7414]

Thanks 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.

[@ManishVyas1]

Great explaination.

[@TechPrimers]

thanks manish. Glad that was useful

[@shivammishra009]

Good one, keep doing good work.

[@leelaprasadjagu3177]

Can you please do a video on spring security using self signed certificates.

[@TechPrimers]

Hi Leela. It's not that easy as it sounds. :) But will try

[@leelaprasadjagu3177]

Tech Primers No problem. Thanks for the videos that you make for us.

[@angelvsaji9230]

Could you please share this ppt sir??

[@KrishnaManohar8021]

can u explain caching also?

[@screwfeaar]

If cart info is cached in browser, why request need to go to same instance always?

[@sanjeevr86]

If it’s opened in mobile later

[@br4676]

Very nice

[@hk_build]

All these servers has same application or diff bcz if same means for tiny change in application makes us to deploy it on all servers it's very expensive...

[@TechPrimers]

It’s the same app. Yes it’s expensive. If we need high availability, then we need to scale.

[@hk_build]

@@TechPrimers is microservice over come this issue am not sure plz confirm

[@sujithg5873]

Could u explain request q example in java

[@TechPrimers]

+Sujith G couldn't get your question. Are you asking for a load balancing example in a java app

[@sujithg5873]

Yess how can we handle huge request in at a time.How can handle in java

[@avinowrastogi4269]

well explained. Thank you.
