This video is much better than many paid videos

Disadvantage: "TCP connections can be ACTIVE but possible have no traffic" => This might not be true. Sure connections b/w clients and servers are kept alive, however in case of LB, and this specific Algorithm, the LB might not be having warmed up connections which are not serving any traffic IMO.

Also, we can clarify that in case of L4 Load Balancers, there are two TCP connection for one request 1. Client <=> LB, 2. LB <=> Server. If we don't clarify this information, people might get confused in this. I really liked you LLD videos and they were super awesome, however for some reason felt in High Level Design, there are some scope of improvement.

I hope you take this positively. Doing a good work. Keep it up :D

Least Response Time was something new, thanks @

[nithishr]

Thanks sir,
Your Playlist is really awesome, Helped a lot in understanding the System Design, I loved your Explaination ❤️

[Umashankar]

Appreciate your hard work, 🙏🏼. Ak request hai ager possible ho system design pe thoda jaldi videos dale.

[karanbangia]

can you pls explain how caching takes place at L7 load balancer and how to invalidate cache, it would be good if you can provide and example

[FazilKhan-vrsw]

Hi, what about consistent Hashing to distribute the traffic. .?

[bobbysadhwani]

Very well explained Sir 🚀.... Can you please attach the ppt in the description, it will be helpful. Thank you.

Hi Shreyansh, waiting for the rest of HDL playlist.

[vamsikumili]

Can a load balancer be a single point of failure? If not, then what measures are taken for it not to be a single point of failure.

[vishalghanghav]

Hello Shreyansh, Maine tumhari playlist start se shuru kii thi, aur bhot sahi jaa raha tha .Par suddenly tumne completely English pe switch kar liya .Any specific reason, Maine specifically isliye ye channel choose kiya tha kyunki tum akele the jo System Design Hindi main sikhaare the .Aur sahi se dekhe to tabse channel ki viewership bhi decline hui hain . Just a feedback

[ramprasadthakur]

Hi Shrayansh do TTFB and latency are same things?

[sakshamsrivastava]

What it means here when we say active connection Shreyansh? Could you elaborate a little.

[VishalSingh-lyvh]

Hello Shreyansh, can you please explain how does consistent hashing fit into this picture?

[kesav]

what about consistent hashing? Load Balancer doesn't use it?

[zmxncbv]

I didn't understood this about Least Connection - "Connection is active but no traffic", what does this mean?

[vishalghanghav]

Hello Shreyansh, Are you planning to cover Docker /Kubernetes /Cloud in near future or will it take time.

[ghayoorhussain]

Sir Should I Start with LLD or HLD Kindly help
