System Design Concepts Course and Interview Prep

[@hayk.simonyan]

Thanks everyone for the positive comments and feedback. And huge thanks to freeCodeCamp for publishing my tutorial.

[@Iith_a]

Great work! You sound really tired.. hope you’re having a good day Homie!

[@mma-dost]

is it enough for a fresher just out of the college ?

[@mg-ht9ir]

I have understood this now what should I watch

[@minhbui5622]

Subscribed your channel. Thank you for your hard work 🎉

[@portfedh]

Great tutorial! So clear and easy to follow. Like the accent too!

[@otaku4life549]

This was the best ever system design course on the internet. He explained literally everything you need to know, in simple terms while also going in detail about their structure and used diagrams making it visually appealing. It has everything I wanted to know about. Like, how is this gold, no diamond gem content for FREE? He explained all the topics so well I know finally understand it, finally!!!! I have been looking for a course like this for a long time. In and under 1 HOUR all the necessary topics including NETWORKING basics was taught in it. I really hope to see more content like this. Maybe on API design or similar topics.

[@hayk.simonyan]

I'm so happy to hear that the course exceeded your expectations and helped you finally grasp these concepts. I do have plans to cover more advanced topics like API design in more detail in the future. So stay tuned!

[@jacobsurles7555]

Man, you really summed it up succinctly. I've spent years studying IT and in 1 hour you've helped coalesce so many concepts that I suddenly feel like I understand the bigger picture in a way that's functional. Thank you so much.

[@IceyBoy47]

Do you know any channel or course with great content in system design?

[@Abhi-n4b]

Yes

[@aleksandrmatyka3118]

you don't need more, you just need separate course on each topic, like nginx, load balancers, db, ci/cd, aws/azure etc

[@Coding101-nb5ej]

This is hands down the best system design course I've come across. So clear, concise, and packed with the exact information I needed ♥I actually saw this before on Hayk's channel but just rewatched it fully here 🙃

[@karengomez3143]

The NoSQL non schema explanation is really good. It's schema less since they drop consistency from ACID concept, they're truly flexible if you understand they don't use foreign keys, it's more like a sticky note board concept. About the DB performance strategies, from catching (to invest in time response), indexing to frequently accessed columns and query optimization through a plan or SQL query analyzer tool.

[@stachowi]

WOW, this was fantastic. Loved how you started with the basics and scaled up. 10/10.

[@hayk.simonyan]

thanks!

[@stachowi]

@@hayk.simonyan i just watched a bunch of videos on your channel and subbed, amazing content

[@hayk.simonyan]

​@@stachowi glad to hear that. Expect many more tutorials on my channel!

[@Deimoc]

Amazing video! I have never seen a video so well-made about system design. I watched it in one sitting and never got bored.

[@hayk.simonyan]

Awesome! I'm thrilled to hear that.

[@phoddaal7130]

Is it about HLD ?

[@danielislam]

Amazing course, describing exactly everything you need to know to build a system from a broad, explanatory overview, into the nitty gritty specifics. I spent over a year piecing together the information in this video by myself so i could understand software systems, learning as I went, and it was hell. I wish i had found this video 2 years ago and saved myself so much headache

[@kapilkanur]

Thanks

[@theannonymous1430]

I was looking for quick overview of system design before diving deep into it, and that's the best video I've found on KZbin ❤

[@RemyEFrancis]

This is the best summary and high-level explanation I've seen of these concepts so far. Cheers!

[@bapzishere]

One problem noticed in the earlier section of the video hence correcting it , CI CD pipelines should never directly push code to production environment , this needs to be deployed to clone of production environment like a stage or beta environment where the artifacts under go load , regression and functionality testing which includes the capacity of the environment to handle load , input validation testing to check for common attack vectors like XSS , CSRF and SQL injections are tested using fuzzing. The code deployed also undergoes security scan / vulnerability scans and then through green blue architecture using weights only limited traffic is sent for the Stake holders to test the application and give their approval for cutover to production.

[@hayk.simonyan]

It ultimately depends on how the CI/CD pipeline is configured and the specific context of the company. I've worked in companies where they directly push code to production in CI/CD, this is especially the case for startups and smaller companies, if they have e2e and integration testing integrated into their CI/CD, they can often deploy to production more quickly than larger enterprises due to less bureaucracy and simpler processes. But obviously it's a trade-off between speed and risk and each team needs to find the right balance for their needs.

[@bapzishere]

@hayk.simonyan Agreed it depends upon the risk appetite of the organization, but it is prudent for an organization to follow risk and change management procedures before using CI/CD to directly deploy to the production environment.

[@Earl_E_Burd]

@@bapzishere There's: ideally, according to the textbook, how things should be done. And there's: boss's boss says to just get it done the improper way. Guess which one wins and leads to Crowdstrike-esque type of situations all the time on a smaller scale? Until someone's an engineer they don't realize how much contempt leadership has for their pesky IT services that run their organization's business processes. In the meeting the engineer says, "We really should be automating a process to test for [the things you listed]" and someone says "noted, but push the updates anyways." Then guess who gets to put out the inevitable fires at all hours and be indirectly blamed for the outage, too? Did I mention the high burnout rate in this field? Checkout sysadmin subreddit for testimonials.

[@bapzishere]

@@Earl_E_Burd Its not clear about true root cause of Crowd strike issue . as the only official reasoning that was provided so far, was the failing of testing tools , which means proper testing was not performed , than no testing at all , unless you have inside information , Please feel free to share , Plus the boss way doesn't work if the organization follows proper certification like PCI-DSS , HIPAA , SOC Type 1 -2 , ISO ,GDPR etc. These certified companies are bound to follow proper regulations which includes internal and external audits ,which involves stakeholders and board of directors , not a single entity like the boss of a department. if the organization is found failing to follow regulations during audits , that leads to hefty fines and cancellation of licenses , Thus for business continuity with proper regulations , Risk and change management is followed in the organizations which are certified to the mentioned regulations and certifications mentioned above. You can check out artifacts from Microsoft azure and AWS cloud services about their certifications and which regulations they adhere during their day to day operations.

[@pavanimmadisetty5099]

First of all, a great great tutorial on System Design concepts. It's not a deep dive, but kind of what concepts are there and their basic definitions with very nice animations. I wish you dive a little bit more into Load balancer topic. By the way, the audio is emotion less. End of the day, a great tutorial covering every concept of system design. Super duper overview and highly recommended.

@@andreyaires226 was talking about how they pushed the code directly to production and didnt run it through tests as said in this video

[@beershigachi4797]

Oh I thought it was more like they didn’t review test cases properly. It’s so dumb if they actually pushed the commit/change directly to the production. That means they don’t even have branch protections which hard to assume they are that bad. But who knows lol
