I have done a couple of system design courses on Udemy and watched a bunch on YouTube as well, but none of them are even close to this.

What differentiates this course from the rest,

1. This course focuses on how to develop the intuition instead of question-answer type
2. It also highlights on how to think about businesses and product which is a very essential quality for Senior Engineers
3. The discussion doesn't start with different boxes/services already drawn and then explaining what each box does. We start with our basic intuition of how our system looks on Day 0 and then we understand what would be a problem with this design when we scale and then try to address each of them.
4. Discussions aren't about how to design Instagram, Cricbuzz, or E-Commerce but rather focus on a specific problem and then discuss deep on that. Ex: Image upload service, Flash sale, commentary for live match etc
5. We also realize how easy it is to prototype what we have learnt

One can understand how much passion and depth Arpit goes in his YouTube videos as well

Previously, I had a fixed mindset regarding how I was going to tackle any system design question. Start with the functional and non-functional requirements, do some back-of-the-hand calculations to depict the scale of the system, start drawing boxes for application servers, load balancers, queues, and databases. While this approach works most of the time for cracking a few interview rounds, Arpit’s course forces you to ditch this conventional thought process and makes you dive deeper into systems and their actual implementations.

This course definitely is a goldmine not only in terms of the content but most importantly, how it sparks curiosity within you to think of system designs beyond just interviews.

1. This course will teach you how to build a solution for any system from the ground up with the right intuition and thought process.
2. Arpit has very smartly covered almost all the fundamental systems out there so that any new system can be easily built on top of it. “Just mix and match”.
3. One particular thing I liked about the course was the prototypes he created to explain the concepts. I mean it’s one thing to know the concept and completely different to see it live in action. Kudos for putting in the efforts to make the course more engaging.
4. If you were ever curious about how systems like the Flash sale, Cricbuzz commentary, Cricket live feed (My favourite discussion) work, look no further because these discussions will literally make you admire how awesome engineering truly is.

A course is only as good as the instructor and Surprise!! Surprise!! Arpit is too good at the teaching part as well. You can sense the enthusiasm and curiosity in his way of teaching as well. He would patiently answer all the questions asked even though the class duration was well past 4 hours. He is open to new ideas and solutions and doesn’t make you feel any lesser even for a bit.

Any senior engineer looking to make an impact at their workplace or waiting for that engineering spark to be reignited again, this course is a must! Thank you for proving that true engineering is well beyond interviews. "SUPERB!"

This was the first one of the kind Cohort that I enrolled in. The way Arpit teaches is fabulous. I would say it is not even a teaching but feels more like an actual discussion that would go into an engineer's day-to-day life. He carries total empathy for a learner. The depth and details he carries in everything he says are fantastic. All the doubts and discussions will have an answer from Arpit. Folks tuning in to every cohort have the brightest minds, and the way discussion happens in cohort with Arpit along with such minds, is just a treat to experience.

What I loved the most was brainstorming sessions. It's never a monologue from Arpit. Sometimes we start to build and would never ever feel that we might be building something so big in just one half of the cohort's session, that too with proper brainstorming from people. The way he helps people to start dissecting the problem; feels like he is just showing the light, others are building the system unknowingly, and feels amazing after we see the output. The way he sparks the decision-making processes helps to build the right intuition, goes deep into the details, and picks every bit and piece of the system is just fantastic. It makes the session the most engaging.

You will get the hands-on experience of picking the simplicity of the system, importance of knowing the basics and other concepts in engineering, and dealing with the tradeoffs of every technology, and mostly the intuition-building

If I have to point out the learnings, they are something like this; and I believe most of the other people in the cohort would agree with me on this;

• Simple systems scale.
• Always prototype and implement.
• System design is like Lego blocks; you just have to place the right component in the right place, and it's not something that will be correct in the first iteration.
• Know the basics and concepts, then just pick it up and place it; you'll build crazy stuff.
• And probably the best: you get some, you lose some. Not a single system exists that can do everything.

This is not an ordinary system design cohort, you will ACTUALLY build systems that scale; for millions of users. And no joy is more than seeing it work.

Arpit is undoubtedly one of the best engineers I've seen in my life. Started following his content on youtube quite a few months back and really liked the way he dives deep on interesting core topics. That brought me to his System Design Masterclass course. The initial Indian mindset made me contemplate on the price of the course but boy oh boy! I'm not regretting even a single bit for what the course was priced at! :)

This is a goldmine of content and as I say, if not all, most who have taken the course would agree that Arpit has truly sparked the engineering curiosity. He offers incredible value in what he teaches. Not exaggerating but I've had "wow" moments in every single class.

Arpit's credentials in engineering is as good as it comes. He is a seasoned pro and it shows in every session, the love and passion for engineering and his craft. With just 3 years of experience, when I entered the course, I was blown away in the first week itself. A serious eye opener for me into building systems for scale.

Arpit has curated the syllabus very beautifully and paces it really well. I'd really suggest to take the interactive live cohort rather than buying the compiled course cause live sessions are just something else! Its truly interactive. Almost every system is built by brainstorming with the folks in the cohort and Arpit helps converge to the right intuition and idea going step by step from scratch, questioning every decision made from the problem statement, design and implementation perspectives in depth. In short by the end of each system design you have the entire design laid out to you in which you understand the purpose of every component used, what it solves for and why this and not anything else, cause you were part of a lengthy discussion that arrived to it. Truly awesome stuff!

Its not only theory or surface level, he emphasizes so much on building prototypes for the concepts and systems we build in the cohort and he does a code walkthrough and explains his prototypes to show that its not hard to build prototypes. This also solidifies your understanding in the concept better as you often uncover interesting challenges when implementing. You also get access to a community and many great folks in the cohort. I felt like the dumbest person in the cohort and absolutely loved that cause there was so much to learn every time.

His patience and love for the work he does is so admirable and inspiring. Once the session is done he is open to taking and answering questions for however long it takes. Does not shy away or asks to stop asking questions after each session. I've seen this QnA sessions go for so long and he doesn't even flinch or calls quits. Massive respect for this Arpit!

Overall one of the best investments I've made in myself for my career.

I thank Arpit for this brilliant cohort and would 100% recommend it to anyone who has some experience in the field and looking to scale up to be senior engineer wanting to build systems the right way.

Don't miss out folks!

"The Best Real World System Design" course in market right now.

Arpit touches upon some really interesting areas in system design. He doesn't just draw the boxes, he really focuses on the implementation details of the system. For example,

• what query you would use to build this system and how would you optimise it step by step as per your requirement.
• How you deal with tradeoffs.
• What is the order in which the execution should happen. What race conditions we might land up into.
• How to simplify your constraints like we do in real world No Magic.

He explained and "actually discussed" so many different designs in a period of 2 months. Hats off man.

He actually focuses a lot on building your intuition. I would Highly recommend this course to anyone who is looking for building the intuition and not just the theory.

Arpit is a great guide, his passion for learning and making others learn as well is remarkable. I had been following his YouTube videos for long and the way he approached and explained problems motivated me to take this course.

For sure, it's been one of the best decisions. Few principles that he emphasizes on have been key take aways for me [other than building the intuition around taking technical design decisions of course].

1.Simple systems scale best -never over complicate 2. Database is the most brittle component of your system, design it cautiously 3. While designing you always gain some you lose some, you need to decide the best tradeoff for your system. 4. There are always multiple ways of doing things, whenever you think of reactive approach think of proactive as well and vice versa, some scenarios might be best fit in completely contrasting scenarios of your previous design decision. 5. Be self-critic of your design and question every design decision taken to converge to best design.

Somehow, we might be knowing these but how beautifully applying them affected our decisions at every step just ingrained it further.

Before taking this course i went through some comments and feedback for this course out of which 90% were positive however there was one of the comments which stated him as "self-proclaimed industry expert" -to this one i would say he definitely is an expert in what he is teaching and that can be acclaimed by anyone taking this course.

So, I would highly recommend this cohort for anyone who wants to understand how real-world systems work and actively participate in the discussions. Other than live cohort the recorded learning course will be equally helpful for people who want to absorb the concepts at their own pace.

I am absolutely thrilled to share my experience with Arpit System Design Cohort. Participating in this program has been a transformative journey that has enriched my understanding of system design concepts and elevated my skills as a software engineer.

From the very beginning, Arpit's passion for system design and his expertise in the field were evident. His well-structured curriculum and engaging teaching style made complex topics seem approachable and understandable. Arpit's ability to break down intricate design principles into digestible chunks ensured that I never felt overwhelmed.

One of the standout features of this cohort was the emphasis on hands-on learning. Through numerous real-world case studies and practical exercises, I had the opportunity to apply the theoretical knowledge to actual system design scenarios. This experiential learning aspect truly solidified my understanding of the concepts and boosted my confidence in tackling real-world design challenges.

I cannot recommend this Cohort enough for anyone looking to enhance their system design skills. Whether you are a seasoned software engineer or just starting your journey, this program will undoubtedly take your design abilities to new heights. Thank you, Arpit, for your dedication and expertise in guiding us through this enriching experience!

All aspiring programmers who crave to build scalable, lasting distributed systems should attend this program. Arpit always nudges us to be hands-on writing code during the course. He helped in inculcating the process of breaking the problem to minutest bit which make us focus on the crux ignoring the surrounding fluff and go and solve for it. The breadth of coverage is quite comprehensive from CDNs, to storage systems, to caching, to databases, to networking the entire gamut of technology spectrum is given a time slice in the course.

Personally for me this course changed the outlook & perspective of how I view systems and problems. I used to be overwhelmed while dealing with complex microservices. Now I feel this course hast helped me to build a muscle of intuition on how systems are built. This hunch/intuition is driving me now to simplifying solutions, instead of adding boxes to the system, I am striving to build systems which are simple and intuitive.

Kudos Arpit, you are a rockstar & inspirational.

The best course for system design to elevate your engineering career.

I have previously tried many resources for getting better at designing systems at scale. But all of them were more focussed on interview, ending up as drawing some black boxes without understanding them.

This course helps building the intuition on what are the possibilities at every stage in designing the system and how to make a tradeoff between them. Definitely, I recommend people to take up the course.

Thank you Arpit, you are simply amazing. Will definitely be among the best teachers in my life that shaped my learning.

1. The design options at every stage and taking trade-offs between them boosted my system design abilities.
2. The course started from basics to designing complicated systems and connecting the topics from previous weeks. This helped elevating my thought process based on the lego blocks.

Before attending this course, my interest towards learnings B Trees or Graphs is less interesting and boring. Once Arpit has explained about DB internals in one of our cohort design discussion's and how these data structures are being used and why in a certain way, my curiosity has increased a lot.

Now I am interested towards learnings every internals of systems like e.g Docker, Kubernetes, Kafka, Bit-cask, Redis and how the data is being stored & what trade offs have been taken and especially what are they compromising on in order to achieve consistency, reliability or durability.

This cohort from Arpit is worth every penny spent and is just a beginning for me/everyone in order to become better engineer. I would recommend every engineer to take part of this course and be a 10x Engineer. Thank you Arpit a lot, kudos to you for the hard work on creating of the course content and patiently clearing every engineer doubts.

Arpit's system design course stands out as one of the best available options. He places a strong emphasis on constructing systems while taking into account intricate low-level implementation details. Throughout the span of 8 weeks, we engaged in discussions about numerous systems and participated in a multitude of brainstorming and question-answer sessions within a closely-knit cohort. I will always cherish the following key takeaways from the course:

1. The inevitability of trade-offs.
2. The prioritization sequence: Business, followed by product, and finally engineering.
3. The essence of system design lies not in merely sketching boxes but in comprehending the intricacies of low-level implementation, all while considering the cost-to-performance ratio.

The last time I maintained such unwavering focus during four-hour-long sessions was back in my days of preparing for the JEE. I wholeheartedly recommend this course to anyone seeking to gain expertise in designing real-world systems.

I recently completed the System Design Masterclass, and it surpassed all my expectations. Arpit's approach transcends traditional box-drawing exercises, delving deep into the intricate implementation details that distinguish this course.

A standout feature is Arpit's emphasis on practicality. Rather than presenting abstract concepts, he guides you through choosing the right queries for system development and optimising them step-by-step based on specific requirements. The course fearlessly addresses tradeoffs, offering valuable insights for informed decision-making.

In just two months, Arpit covered an impressive array of diverse designs, fostering a profound understanding of system design principles. His dedication to facilitating genuine discussions, not just surface-level explanations, is truly commendable.

I had the pleasure of enrolling in Arpit Bhayani's System Design Masterclass course, and it was truly an awe-inspiring experience! Arpit's teaching style is beyond compare; he effortlessly breaks down complex topics into small, easily understandable units, making the learning process enjoyable and effective. The systems discussed in the course were pragmatic and immediately applicable to real-world projects. I found myself confidently applying the knowledge gained in my work projects.

Every penny invested in this course was worth it and more. What sets Arpit apart is his exceptional dedication to his students. He goes above and beyond by spending a significant amount of additional time post-session to answer every single question with great detail and patience. On several occasions, the Q&A sessions extended for an impressive 2.5 hours beyond the regular 2-hour session, ensuring that all questions were answered.

I cannot recommend this course highly enough to anyone looking to enhance their system design skills. It's an invaluable resource led by an outstanding instructor, and I'm grateful for the knowledge and support I received throughout the course.

A big thank you, Arpit, for this fantastic learning journey!

Two words - Absolutely fantastic! This systems design course has been nothing short of a revelation. It delves deep into intricate system design engineering concepts, offering a comprehensive understanding that encourages critical thinking while discouraging broad generalizations. The course does so, while discussing the business implications for each decision that is taken, which you don't get to learn anywhere else.

I was an avid viewer of Arpit's YouTube channel from long before I took this course and his website has a ton of resources if someone actually takes the time to go through those topics. The beauty of the course is that once the system is designed, Arpit makes sure to specify how can a similar system be implemented locally (where ever feasible). I have no doubt that I'll continue to refer back to the meticulously prepared class notes and insightful recordings in the future. I have nothing but admiration for this course and I am definitely excited to take his Redis internals course sometime in the future!

Enrolling in this course has been a game-changer, and I can't recommend it enough. Thank you, Arpit!

Arpit has truly poured his soul into this course.

Beyond the technical knowledge, I admire him for his passion for technology. Not only does he possess excellent technical acumen, but he also excels in articulating and demystifying complex technical concepts.

Decoding intricate systems and making them easy to comprehend is his forte. I also appreciated the structure and delivery of the content; the three-hour-long sessions never felt monotonous or repetitive.

I would highly recommend this course to anyone eager to learn how complex systems work.

I have personally learned a lot of concepts and gained a great deal of confidence in approaching challenging technical decisions. The terms and concepts that were once unfamiliar to me before the course are now very clear.

My intuition and curiosity have been ignited, and a solid foundation has been laid to understand and build complex systems without unnecessary complications.

The best tech investment that I have ever done by enrolling in this course. Excellent learning through the live interactive classes and cohort mates. 1000% recommended for all software engineers!

I was super impressed with the concurrency part of the lectures having pessimistic locking with select queries extending it to various booking systems -> task scheduler -> MessageBroker, scaling web sockets for millions, design of loader balancer and S3 storage.

I am much more confident now with the strong intuition and right way to design any system. I am able to recognise the patterns in the system design :)

Course has been nothing short of transformative for my understanding of complex systems design architecture. Arpit provided his valuable real-life experience that he encountered over his last decade of experience, that truly enriched my learning experience a lot.

Through practical experience of Arpit and peers I gained an understanding of designing scalable, reliable, available and most importantly business aligned architectures.

I highly recommend this course to anyone looking to enhance their skillset in designing reliable, efficient and business aligned architecture/products.

Whether you're an experience or beginner, the engaging learning environment will undoubtedly propel your career to new heights.

Your videos on Youtube sparkled my interest in backend engineering, and I've learnt a lot through them and they've made me a better engineer. I feel you don't get enough credit for your fabulous channel, . I always felt it difficult to understand content in this domain, but when you used to explain, everything felt so easy and intuitive. That is the reason I signed up for this course when couple of people recommended me to do so.

In the first couple of sessions itself, I was amazed by the amount of stuff I learnt, and it siply continued in all the sessions. The course recordings are like a lifelong treasure which I will keep going back to for lifetime. The amount of value you deliver by this course is beyond words.

Two of the most important things in engineering is to 1) ask the right questions and 2) How to approach a problem and think about it. You showed us how to do these two very well.

The interactive session format is very helpful. This way we think about the solution actively, and I loved how the inputs of different people in the discussion ultimately leads to the solution. And Some very brilliant engineers in the cohort out there. Your dedication to run this course and channel is superb, it shows your deep passion about this field.

The pre-reads section as well as suggestions to read/explore/implement after the sessions helps us get even better as an engineer.

All in all, 'Learning full, money and time vasool'. Thanks a lot for this.

This course is different where depth and breadth regard. I am a seasoned Engineer who has been working for many years. I have never found such a course before. It does the following.

1. It shifts your focus from "interview mug up" to pure Engineering practice. Henceforth you will never be overwhelmed/ intimidated by the number of interview questions asked in different companies. Rather you will have amazing fundamental knowledge out of this course, which will help you to come up with the answer of an unknown interview question during the interview. Also you can apply this knowledge in work.
2. It helps to mitigate any GAP of knowledge of Engineering that a senior Engineer should have.
3. It points out what we should do regularly such as reading Engineering papers, trying to think about the trade offs of different systems, thinking about the use cases of different solutions and thinking why they at all evolved etc.
4. It will help you to think smart such as "not reinventing the wheel" (which kills precious time) and just improving an already evolved system to make it better.

In short you will get pointers to different knowledge areas which, may be you never knew. You can think of it as another Engineering course with the focus on the application in real world use cases of system design.

I wish Arpit all the best.

These couple of months was truly an exceptional learning journey. What stood out for me was the immersive approach to implementation. Arpit took us through the intricate details of each system, allowing us to tackle lower-level challenges and gain a much deeper understanding. This really gave me the confidence to tackle real world problems.

Another highlight were the brainstorming sessions where we freely discussed our ideas and approaches. This not only enriched the learning experience but also exposed us to many different approaches to solve the problem at hand. A great part of the learning was through the questions and discussions that others brought forward.

Each session was filled with valuable insights and practical knowledge. The course struck the perfect balance between theoretical concepts and practical considerations, equipping us with the know-how of designing robust systems. We delved into aspects like extensibility of our systems and cost optimization as well, which was really insightful.

Overall, it was a great learning experience, and I had the best time! This course is gold and truly does live up to the #AsliEngineering message. Highly recommended

I can't imagine a better system design resource.

Arpit starts with the simplest possible solution and strongly emphasises introducing complexities only when necessary.

He encourages you to think of the technical, product and business motivations behind a system. He doesn't really prescribe solutions to problems but helps you build intuitions behind usage of technologies. 11/10, would highly recommend.

Things that worked out the best for me were:

1. Religiously starting with the simplest possible solution
2. Strong emphasis on introducing complexities only when necessary
3. Encouragement of product and business thinking
4. Technical depth: Arpit always answers the how and why behind every question

Thinking is golden but thinking how to think is platinum!

What I particularly like about the course is his focus on building core intuitions rather than making the students learn a specific topic or a concept. There is dearth of content online that focuses on learning as an end rather than a means to an end (primarily job interviews). In this landscape, Arpit's course is a breath of fresh air. I would highly recommend this course to any software engineer who is seriously interested in leveling up their thought process when it comes to designing long term sustainable distributed systems.

Two things that stood out for me were - deep-dives and out-of-the-box approaches. Always striving to go one layer (and sometimes uncomfortably so) deeper to understand the underlying worked out very well for me as an exercise. I have not been used to doing this for the major part of my career, and specifically more so after leaving college.

Going out of the box, in some cases where the trick is not in the engineering itself but how the real world operates was specifically very interesting to me. The example of how a certain engineer went ahead and negotiated the contract rather than solely focusing on optimizations, relaxing product constraints to make systems cheaper/simpler were 2 such examples that I can recall off the top of my head.
