This was a fantastic video, I'm never missing any video from this series ever. Definitely going to implement a 3 tier architecture next coming months and try different things from your videos, thanks a lot man ❤

[@codebreakthrough]

Exciting! I should have more soon 👍🏻

[@rida_brahim]

Quality work really, i really appreciate your time you put on to enlighten someone like me who gotta learn the hard way

[@exstrut]

Bruh! I'm watching your these long videos without a blink, no dopamine theory when creator is this good

[@raf22nd]

I'm just getting into fullstack development by following the free Fullstack Open course and your channel has helped me understand the bigger picture and how it all comes together. Thanks for your explanations and look forward to more videos on databases!

[@EthanHunt-z8r]

I have been throgh a lot of course on System Design this series of video has been the most amazing System Design seires on youtube just keep the good work

[@anon10101]

caleb this series is phenomenal work

[@onkarkawathe1369]

Brooo.. you killed it👏 Fantastic explanation of scaling

[@miyu545]

Great to see videos of this nature.

[@Not_The_Pizza_Guy]

Great video Caleb. Keep up the good work man!

[@AlperShal]

Reeeeaaaally great lesson. Thanks for this. Just one question. Why load balancer is not considered as a SPOF? If lb goes down doesn't app go down too?

[@perfect10vintage87]

Appreciate your clear explanations. Thanks so much Caleb 💯

[@KeshariPiyush24]

Thanks man, you are amazing. Keep making these videos.

[@AmanSingh-yj4ul]

Great video Caleb!

[@tahaalnufaili8838]

great explanation!

[@VadimZverev]

isn't the load balancer a single point of failure itself?

[@tahaalnufaili8838]

i thought so as well. articles online say at least "two LBs in front of your infrastructure" is recommended. You can use a Active/Passive load balancers or a Active/Active load balancers approach

[@lifegoesonmovewithit.3249]

When is it the write time to start learning system design in accordance to your Backend engineering roadmap?

[@Manu-e2r]

There is no sequencing in the videos title, can you add that, that would be very helpful

[@arcadeduo7101]

Me, using this video to build my thesis :>

[@Dallas4090]

Right on time

[@thomsonkaisi6304]

You are a G.O.A.T❤🎉

[@MuhammadMujtaba-d2d]

I have a question, If we are using horizontal scaling and there are multiple servers deployed, so each server will have its own cache or all the servers will have one redis cache? Would we have to deploy a separate service for redis?

[@beast7815]

What’s your resources you have based on?

[@aadarshyadav6650]

Great love your videos sir

[@Artifact-q6g]

Thank you very much!

[@ChandanKumar-of1je]

ThankYou

[@rselwyn1000]

Caleb its very hard to find someone to answer this. Can you or anyone reading this tell me If I have installed Visual Studio 2022 on my new PC, how do I migrate (move) my VS 2013 projects ? Is it as simple as moving the 2013 projects folder to the VS 2022 folder? Thanks

[@ABDeccan]

@rselwyn1000, Just try typing 2022 in your search prompt (after pressing the Windows key once) and see if you are able to see "Visual Studio 2022" in the search results. Alternatively, you could bring up the Windows Run prompt (Windows key + R) and type 'devenv'. This should also bring up a visual studio if installed on your machine. Once its up, you can check its version from the Help -> About Visual Studio. For migrating the older projects to 2022, just launch visual studio 2022 and from there, open the previous version projects. This should take care of automatically backing up older version projects and migrating to latest version. Please note you may need to make some code / dependency changes.

Thanks for sharing

[@Python_Scott]

👍 I like you teaching style.. Do you know Mojo ❓❓ ❓ ❓ It's early enough to get in on it from it's beginning. I think it will be the ultimate language. 👍👍 👍 👍

[@skt7088]

Where is front end server? Instead of that cdn being used?

[@learnwithnayem5721]

When the next video will come?

[@aviralsinghal5937]

Hey just saw your video. Is there anymore space for the mentorship program? Please would genuinely love to join!

[@codebreakthrough]

Hey! Go ahead and fill out the app and you can mention your KZbin comment in the answers 🙂

[@aviralsinghal5937]

@@codebreakthrough Hey thank you so much! EVen though I know you're focusing on US, I'm from Australia but have always wanted to be mentored by senior engineers, an experience that I never really got - thanks again

[@Prizkov99]

Bro where the chain at?

[@amitperane1302]

Nice video but change board
