I love how the topics are connected to one another in a simple and neat way.

[@pepperdayjackpac4521]

dont you mean "neet" way?

[@BERNOUSSAMA]

can't believe he missed it

[@its_me_tabs]

In a neet way!

System design concepts explained in the video 👇 1. Vertical scaling - refers to increasing the resources (such as CPU, memory, or storage) of a single machine to improve its performance or handle higher workloads. 2. Horizontal scaling -adding more servers to a system to distribute the workload and increase overall capacity and performance. 3. Load balancer - A load balancer is a network device or software that evenly distributes incoming network traffic across multiple servers or resources to optimize performance and ensure high availability. 4. Content delivery networks - Content Delivery Networks (CDNs) are distributed networks of servers located geographically closer to end users, designed to deliver web content efficiently by caching and serving it from nearby locations 5. Caching - Caching is the process of storing frequently accessed data or content in a temporary storage location (cache) to improve retrieval speed and reduce the need for repeated requests 6. Internet Protocol Address - An IP address is a unique numerical label assigned to each device connected to a computer network 7. TCP - TCP (Transmission Control Protocol) is a communication protocol that ensures reliable, connection-oriented transmission of data by dividing it into smaller packets, numbering them, and reassembling them at the receiving end. 8. DNS - DNS (Domain Name System) is a decentralized naming system that translates human-readable domain names into IP addresses 9. HTTP - HTTP (Hypertext Transfer Protocol) is a protocol that governs the communication between web browsers and servers, allowing for the retrieval and transfer of web pages and resources over the internet. 10. REST - REST (Representational State Transfer) is an approach to designing web services that uses standard HTTP methods and URLs to facilitate communication between clients and servers. 11. GraphQL - GraphQL is a query language for APIs that provides a flexible and efficient way for clients to request and retrieve data from servers by allowing them to specify exactly what data they need. Using single query it can fetch multiple resources without overfetching as well. 12. gRPC - gRPC (Google Remote Procedure Call) is an open-source framework that enables efficient communication and interoperation between services by defining the interface and data contracts using Protocol Buffers and facilitating bi-directional streaming and error handling. 13. web sockets - WebSockets is a communication protocol that provides full-duplex, real-time, and bidirectional communication between a client and a server over a single, long-lived connection.WebSockets can be used in applications such as chat systems or real-time collaboration tools, where instant and continuous data exchange between clients and servers is required. 14. SQL - SQL (Structured Query Language) is a programming language used for managing and manipulating relational databases, allowing users to perform tasks such as querying data, defining database structure, and modifying data records. SQL is considered to use when fast retrieval of data is needed 15. ACID compliance - ACID (Atomicity, Consistency, Isolation, Durability) compliance is a set of properties that ensure reliability and integrity in database transactions, guaranteeing that they are executed reliably, consistently, and without interference. 16. NoSQL databases - NoSQL (Not Only SQL) databases are a class of databases that provide flexible, schema-less data models and horizontal scalability, making them suitable for handling large volumes of unstructured or semi-structured data. 17. Sharding - Sharding is a technique in database management where data is horizontally divided and distributed across multiple servers or nodes to improve performance, scalability, and load balancing. 18. Replication - Replication is the process of creating and maintaining identical copies of data across multiple servers or nodes, providing redundancy, fault tolerance, and improved data availability in distributed systems. 19. CAP thoerem - The CAP theorem states that in a distributed system, it is impossible to simultaneously guarantee consistency, availability, and partition tolerance, and therefore, trade-offs must be made between these three properties. 20. Message Queues - Kind of like databases because they have durable storage. They can be replicated for redunduncy or sharded for scalability. This can be used in task distribution and workload decoupling.

Bowing down to this incredibly well made content. Thank you so much!

[@oleshko-g]

Oh. My. Gosh. This is THE most concise video about Systems design I’ve seen. All this fragmented things I’ve heard finally make sense together. Thank you 🙏

[@andrewkicha1628]

Great job, I like how you balance between conciseness and covering just enough details so that people can further learn it if they are interested in a concept

[@AnandSadasivan]

Best ever! Compact and interesting intro to system design concepts!!! Excellent!

[@pirateg3cko]

Thanks! Keep it up, NeetCode!

[@xcoda]

I really loved all the concepts. I'm a front-end heavy full stack developer wanting to upskill in the backend department. These pointers are really helpful. Could anyone point me in the right direction to learn more advanced topics on database designs and it's efficiency?

[@timtim9o5]

Great video. It connected some dots for me. Great content thank you

[@sudiproy4413]

The best part is that I am already familiar with most of the concepts mentioned in the video. Still, I didn't realize it fell under the 'System Design' category since I am a self-taught backend developer.

[@joaquin67]

Interesting. This just further proves that frontend and backend really do have a distinct divide. Client side and server side. Client side definitely focusing more on human interaction, server side focusing more on the "motor/engine" of an app.

[@amcmillion3]

@@joaquin67 Yea. I had it put to me perfectly by a senior on my team. Backend developers are really just data plumbers. We build all the underground plumbing for data to be moved around. Front end developers build the fancy sinks, toilets, showers, etc... that get the data from the plumbing.

[@joaquin67]

@@amcmillion3 I always love hearing the house analogy further improved as both are equally important. For example, I wish I had more outlets in my apartment that was built in the 80s, and more cabinets for things. Likewise, I wish the plumbing in my 2nd restroom didn't have the hot/cold water temperatures reversed. Backend is the bridge between data and frontend, frontend provides interaction between backend and human. Unfortunately, the human is the only level in the stack that can't always be debugged lol

[@sakthipriyane8506]

Thank you for this super understandable explanation.

[@sivan2878]

Awesome summary, I was actually looking for it.

[@Srishti9015]

Great video, this is exactly what i was looking for to prepare for my interview tomorrow. Thanks!

[@SandVision03]

Clear, concise and precise

[@uwontlikeit]

Man I bought your lifetime subscription and I can say you have a talent to explain complex concepts in a simple language. You should expand your course to more areas - for example Cloud services (AWS, GCP, Azure...) - there are tons of content topics there and there are no content for those topics on youtube in terms of explaining as good as yours. You should do it bro!

[@AaronJOlson]

Thank you for making this! Another highly informative video! I am so impressed with your animations. Are you using remotion to make those? Or it is all after effects skills?

[@vishaldesaiVMD]

Wow! This video is impressively well-crafted, managing to be both concise and thorough simultaneously.

[@marshall3900]

omg bro this is so much better than all other vids about system interview that I have seen

[@tomiwaadedokun6638]

Wonderful concept explanation @NeetCode

[@vitalyl1327]

NoSQL is older than relational databases. All DBMSes were NoSQL prior to that Codd paper. All the flavours existed back then, in the late 60s - early 70s - document, hierarchical, graph-based.

[@joeeeee8738]

Really? Wow I wouldn't have thought so!

Very Useful content, I loved the Design pattern video also. Had an interview on Friday, They asked about the strategy pattern, I told them how to Make FilterStrategy. 🤣 The round was was supposed to be 1 hour long but ended in half hour. I answered almost all questions. But there is no response from them.

[@sunithaarganurkar7486]

Where did you get filter strategy video in this channel?

how did it go?

[@spooder5022]

did you hear back?

[@HikariSkript]

@@spooder5022 Hi, I got the response and cleared all rounds, there was a round with VP after that. The HR is delaying the offer tho, He said he will give the offer last Monday. I called again and again. No response. Meanwhile I got an offer from an Ad Tech company. The process was very smooth interactive interviews. Its giving 30% hike. The above one is a Data Science AI company. I am very confused should I pressurize the other company for offer or go with ad tech.
