@TechLead

Please "like" the video to support my technical content, and I will be happy to make more for you 👍 I'll do one for mobile systems design if we can hit 5,000 likes.

Transitions between topics is seamless, awesome!

@stevenmccarther5836

In Boot Camp and a relative suggested I review this video.  Very much appreciated.

@fredwu6812

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.

@willdedill

The BEST TechLead video I ever watched hands down, you see he didn’t mention a single second that he’s an ex-Google ex-Facebook whatever, nor talking about his wife. 
Straight to the point, thank yoi for breaking this concept to us 😅

@chevalier5691

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.

@BillionaireDeveloper

I can not pass a single day without watching the videos of TechLead.

@waruwaruwaru

This is probably my favorite video from TechLead so far.

@domibr4966

I don't even know the least bit about computer science or IT. I just love to listen to the Tech Lead.

@mr.unknown4124

Eleven minutes of Wisdom. Thank you so much. <3

@sasamilic720

props for covering this all in 11 minutes

@ByteMock

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.

@DevenSitapara

Very high quality content in few min, which takes years to learn

@MrRoops3

TechLead has the best content...He is the Master.. Respect the Master 🙏

@itarukmakto

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

@mageec1100

you cannot love his style , you have to recngnize that the skills of techlead are far better than other tech youtubers

@JayPatel12928

Damn, so that’s why he’s the techlead. 🐐
