- Please like the video. Ex-Google TechLead talks through core concepts for a systems design interview. Visit brilliant.org/TechLead/ to learn math, science, and computer science with new interactive courses, and get 20% off premium.
I cover the systems design interview in more detail in my program Tech Interview Pro ( techinterviewpro.com/ ) if you are interested in learning more. We also do bi-weekly Live Q&As so have a look.
In this video, we discuss load balancing, CDNs, database replication, sharding, caching layers, database schema and indexes, distributed filesystems, and other ways to scale an application. You don't want to scale your design too early or needlessly, but consider where the bottlenecks are. Sometimes you will need database sharding for instance, while other times you may not need a database at all (ie., if the data does not need to persist to disk). Note: the concepts will differ somewhat for a frontend or mobile systems design, which are more focused on the client-side architecture and software design patterns.

Please "like" the video to support my technical content, and I will be happy to make more for you đ I'll do one for mobile systems design if we can hit 5,000 likes.
can you do a vid on chainlink or decentralized oracles or at least how to use blockchains for regular apps
TechLead hopefully weâll get there because these videos are so interesting
tech lead, could you tell us where to systematically study âsystem designâ?
please do more , you know most of your audience are nerds which means we are emotionally disabled most of us don't put likes but in reality we love your content and we always comeback .
so please do more even if we did not reach the 5000 .
when i hear a guy like you i feel it is the perfect way to check mh skills and way of thinking .
Don't buy too early. There's gonna be a 70% off fire sale. Be patient guys
This is probably my favorite video from TechLead so far.
Me too

@@manojgt8660 is it simple way to get or there are lot of water?
@@cinderellarouge Sorry I'm not able to understand your question. Can you be more clear?
@@manojgt8660 "a lot of water" that means 20% useful information and other is trush ..
@@cinderellarouge I would say 10%. This video is good for talking with others on system design. But not good for interview preparation.
@@manojgt8660 No, I'm about your recommended book.
Old Tech lead before his villain arc is actually pretty helpful
Tech Lead effortlessly demonstrating why he's the Tech Lead. High quality content.
The TechLead ran out of trolling/sarcastic video ideas, so The TechLead actually put out useful content that he learned from being an Ex-Google, Ex-Facebook Engineer (as a Millionaire).
Hard truth is, TechLead is not that good at these useful tech contents, compared to other top tech vloggers on CZcams. What he does best is trolling/sarcasm/reality-show kinds of videos.
@@boranshao Can you name a few?
Boran Shao Yes can you name a few?
@@boranshao Which other top tech vloggers?
(as single)
This is like one of the old Tech Lead videos that got me to subscribe in the first place! I love these type of technical topics, keep them coming! :D
Those types of videos proves that he is the Real Tech Lead (as a millionaire and an ex Google & Facebook);
yeah or you could just ask my friends over in HR, they'll confirm that for you. HR's the best, what's not to like? (except for the part about firing me of course, but that's a minor detail).
333jas I think because he opened a youtube channel
333jas i thought i made a whole video on this.
Every intern at Google knows this, it's basics.
Kirill I He worked on Facebook, not Google.
This is the reason why I started following TechLead a year ago, , thanks for bringing it back. Love your explanation alot!
This is the first great video that I've loved from Techlead in a while! (Fan since season 1). While life lessons are great, most of your audience may not be in their late 30s/40s, thus not nearly as engaging. These design videos are great, because you explain key terms (CDN/Sharding) in layman's term. The structure is also great Webserver load balancing, into CDN, then into sharding databases. The tables/diagrams worked great too. As a suggestion, I think small code snippets would improve the video even further. I find watching you code entire projects to be hard to follow. We can work out the details ourselves, but code snippets/concepts are great for the youtube format. GJ!
Still one of the best and most concise explanation of key system design concepts on CZcams!
This is definitely one of the more useful vids for techies on this channel. This guy isn't just boasting about being a tech lead. He really is the TechLead.

System Design questions are challenging to prep for. It is a great way to show off your problem-solving ability and personality when compared to whiteboard questions.
The database replication with slave and master and sharding! splitting the tables vertically and horizontally blew my mind like wow ! ps: I am just 2 years into dev so I found all of these concepts very intriguing and exciting!
I don't even know the least bit about computer science or IT. I just love to listen to the Tech Lead.
I can't believe this video exists. This man will singlehandedly helped me and others land a job even 5-10 years from now. I have no experience about scalability because my projects have never needed that much, but now I can atleast understand some terminology that would help a lot in system design interviews.
Please continue with the technical topics, enjoying them so far
props for covering this all in 11 minutes
The guy knows what he is talking about. He is the goddamn Tech Lead!
Funny thing is, this isn't even what I did at FANG. I did mobile development there.
@@TechLead you were overqualified!
@@paulfunigga LOL
@@TechLead this is more for the distributed system back end side. Did you use to work in back end in the past ?
He is also a Fullstack web developer.
this is one of the best videos he's put out
The BEST TechLead video I ever watched hands down, you see he didnât mention a single second that heâs an ex-Google ex-Facebook whatever, nor talking about his wife.
Straight to the point, thank yoi for breaking this concept to us đ
Really appreciate the technical content!
You have everything in such an easy and understandable way. Thank you for such great content đđ
In Boot Camp and a relative suggested I review this video. Very much appreciated.
Nice video! I'm interviewing right now as a sophomore in college and recently failed a systems design interview challenge pretty badly - this definitely covers most of what I should have known.
nice, glad this might help next round!
Transitions between topics is seamless, awesome!
Great video! Liked the clarity, simplicity and structure of the video. The concepts explained are very useful.
You explain things so well. Thanks for this.
This is my favorite episode of coffee time with TTL
LOVE this video! I'll share it with my community with their TPM and Engineering questions!
These technical videos are great! Looking forward to more of these. You should also do podcasts or on Audible so that it's easier to listen when traveling..
Great video. I am almost done with my intern as a software engineer
I learnt some of these concepts when learning about AWS and seems like AWS have made many things easy like auto scaling, load balancing, caching, data replica etc. I wonder how people do things before AWS.
They are still doing medium to large enterprise has there own datacenter and all government offices
Thank you for this video! It was super concise, easy to understand, and overall a very good intro to a lot of these concepts.
Seriously great explanation and examples. That was super helpful!
To paraphrase: There are mainly 3 servers... the techniques to scale them are: Webservers (load balancing), Database servers (Caching, Indexing and Replications), Content Servers (Content Delivery Networks)
for web... Load Balancing - To improve Throughput, Latency and Scalability - NGINX for enterprise, dns load balancing for basic cfg
for caching db - Memcache, Redis, Cassandra.
for caching img/vid/web files - CDN (Distributed File System e.g. Amazon S3)
for db... Replication - Replicate data on multiple Slave DBs for "Read" only and Master for Read+Write
Problem: Simultaneous DB Writes; Solution: Sharding (Horizontal sharding - Data from 1 table is split and each portion is maintained in different/multiple machines)
NoSQL - Not Relational - Essentially key-value pairs - E.g. MongoDB, Amazon's Dynamo DB and FireBase' FireStore
This type of content is the best
This is the TechLead most people respect and cannot beat!
What a great short explanation. You are one of the best developer and human. Thanks.
really appreciate your work! very helpful video! The mobile system design is what I expect mostly. Hit already 1.2k and waiting for your new episode!
What a nice overview! Awesome!
Such a helpful adviceïŒđ
Techlead, this is the time that you are showing us how much power you have. Holy shit!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I think even my university professors cannot even compete with you.
Thanks. Really needed this
Thanks TechLead. Much appreciated.
Im trying to understand "not being able to do range queries" (paraphrasing it) in nosql db. Mongo has range query; other db dont? Can someone explain more?
Great video, studying load balancer & CDN recently
Although I like your "as a millionaire" videos, technical videos are much better. Thanks for this video.
Incredibly helpful! Thank you!
Thank you Tech lead! For all your videos
I can not pass a single day without watching the videos of TechLead.
OMG they are so useful!! thank you!
Thanks, I learned a lot of new stuff.
TechLead has the best content...He is the Master.. Respect the Master đ
Very high quality content in few min, which takes years to learn
I love your videos!! Thank you
Excellent video and well put.
Respect the techlead. Techlead is life.
It's true. I'm your father.
This is a very nice introduction.
This is high quality stuff!!!
Techlead is the type of guy who tests his code after deploying it to production đ
kunal sethi eh i never make coding mistakes anyways. if i do i fix the compiler.
@@TechLead Respect đđ
@@TechLead Kindly fix the Javascript.
Thanks! Amazing video.
This is useful. When I hop I will definitely use this system design course!
Quite intense content, good
Respect the TechLead. great video! so fast and on point. please make a video on system designs interview for sr. software engineers / software architect
This is pure gold
Eleven minutes of Wisdom. Thank you so much.
Make more with more deep explanation, example, use case. Please đ€©
What happens if the load balancing server goes down due to too much traffic? Could you have a hierarchy of load balancers? Or do they normally vertically scaled it to the point where that doesn't happen?
The smartest and funniest and sarcastic Tech Engineer I have ever seen !!! đđđ keep going
This is gold. Can you do another technical video about the tools/services in order to implement the scaling techniques you discussed on the vid? Also, I would be happy to purchase from an affiliate link pointing to books/resources about the topic discussed. Thanks!
Like you, The Respected TechLead, my day starts with coffee âđ
Irresistible Tech you think this is actually coffee?
@@TechLead yes. What is this?
It was helpful to hear the concepts explained differently with a different perspective. This helped clarify some of my confusion. Thanks again!
Too bad we never ran into each other when we were at UCSD. :)
Great quick watch video before a System Design interview.
Tech lead is back!
That was really nice, thanks man.
Good video techlead!
Thanks Sir its really very very helpful , In 10 mins you covered all important key points
Just finished reverse proxy on another channel, and this shows up on my recommendation.
that was super helpful
Thank you even before watching!
Like the video and respect the tech lead, thank you!
More of System Design man.....this was very informative
wow this is a really helpful video, thanks, :)
Great video! Have you ever had to do horizontal or vertical sharding for your personal projects? At what scale more or less does this become a problem?
It totally varies on load and how heavy you're hitting the database. I typically wouldn't worry about it until I'm getting like 300K daily active users before sharding though... I've done both vertical and horizontal sharding but it often is easier to just pay for more RAM and keep things simple.
first time I ever put playback speed below 1x lmao
Yes I checked the speed if I was on fast mode
the best video in a while
Pure gold as always :) TechKing
Really liked the content, hope i can afford this course one day đđ»
This is a great video. Thanks a lot
Thank You, this is what i like from you not talking how awesome you are i can see that no need to say it cause this way it makes you more awesome.
Thank you so much for this
you cannot love his style , you have to recngnize that the skills of techlead are far better than other tech youtubers
Love these kind of videos where he shares he's tech knowledge. More of the same please.
finally tech lead you choose right topic
thanks for making video
keep it up
I would be more interested in Systems Design Interview Concepts as a millionaire. But you cant argue with TechLead.
Very informative video. Thanks for sharing. If possible please share your knowledge more on this Topic. Lots of video coming on youtube about Programming, technology but enterprise level architecture and technic to solve complex problems is not discussed frequently.
Good summary
