System Design for Beginners Course

[@TheEvolvingEngineer]

I am not even a software engineer but the way he started explaining things make so much sense to me and made me stick to the video till the very end. Gaurav knows who make it engaging. Kudos to FCC and Gaurav!!

[@sailendrapamidi]

Exactly my thoughts.

[@magicmedia7950]

That is what system design is all about. It's meant to be understood by the layman. Surprisingly the most important part of programming is not in writing the code rather it's solving a problem using logical sequence that captures everything problem solution(system design). If you are not good at this then programming may not be for you!

[@illuminatidaylight8566]

I want to get placed as a software Engineer so for this should i learn system design ?? Is this video good for a starter ?

[@tazzyw]

@@magicmedia7950 well said

[@mma-dost]

sorry for the late reply but learn system design at the start may be interesting for starting but you need to learn how to write code and make good projects.@@illuminatidaylight8566

[@potatocoder5090]

FreeCodeCamp is amazing! Only yesterday, I was learning Assembly Programming with ARM for beginners on this channel, and today there's a system design course already waiting for me! Thank you Gaurav for creating such a thorough resource for free and FreeCodeCamp for bringing it to millions of learners like me :)

[@KejriwalBhakt]

Just to let others know, Gaurav has started his own startup and is being helped by the startup cell of Maharashtra state to smoothen out the process.

This course introduces system design concepts for building large-scale distributed systems, covering design patterns, data modeling, and implementation considerations. It includes a case study on designing a live streaming video app. Highlights: 00:00 This course provides a detailed introduction to system design for beginners, focusing on engineering design patterns for building large-scale distributed systems and converting business requirements into technical solutions. -Large scale distributed systems involve handling high data volumes and user traffic, requiring servers distributed globally for performance and fault tolerance. -Design patterns are essential practices used by engineers to solve common problems efficiently, like distributing content to millions of users through a publisher-subscriber model. -Engineers convert business requirements into technical solutions by defining data structures, endpoints for data manipulation, and ensuring system reliability, scalability, and maintainability. 09:06 Designing a system requires considering extensibility, testing, and scalability. Testing the design before coding is crucial for system reliability and user satisfaction. -Importance of testing system design before coding for reliability and scalability. -Considerations for live streaming system design, including requirements like video processing, user interactions, and scalability. -Challenges in system design, such as failure scenarios, feature requests, and balancing front-end UI design with backend system design. 17:07 The video discusses designing backend APIs for real-time querying, including getting video frames and posting comments, and the database structure needed to support these functionalities. -Designing backend APIs for real-time querying and returning video frames based on device type and offset. -Implementing APIs for posting comments and manipulating data in the server. -Discussing the database structure for storing comments, users, and videos to support the defined APIs. 25:16 The video discusses the difference between stateful and stateless protocols, highlighting how stateless protocols like HTTP benefit by simplifying client code and making the network more efficient. It also explains the importance of choosing appropriate network protocols and database solutions based on system requirements. -Stateless protocols like HTTP simplify client code and make the network more efficient by avoiding duplicate requests, benefiting system performance. -Choosing the right network protocols, such as TCP for reliability or UDP for real-time efficiency, is crucial for effective video transmission and system design. -Selecting suitable database solutions, like NoSQL for scalability in handling complex data structures, plays a vital role in meeting system requirements and optimizing performance. 33:19 Highly reliable network and efficient camera are crucial for live video streaming. Different resolutions and formats are needed to cater to various devices and user preferences. -Importance of network reliability and protocol for live video streaming. RTMP protocol ensures data integrity during video transmission. -Significance of transforming raw video footage into different resolutions and formats to meet user device requirements. Considerations for resolution preferences and customer feedback. -Utilizing the map reduce design pattern to process and convert raw video data efficiently. Exploring the use of different servers and compression techniques in the conversion process. 41:25 System design for large-scale distributed systems involves considerations like performance, cost, and engineering effort. Utilizing CDN solutions and well-tested tools from cloud providers can optimize system performance and cost-effectiveness. -Importance of utilizing CDN solutions and cloud provider tools for optimizing system performance and cost-effectiveness in large-scale distributed systems. -Challenges and considerations in system design, including authentication for content delivery through CDNs and the trade-offs between cost and performance. -The significance of low-level design in system architecture, focusing on interactions between system components, network calls, and data handling. 49:30 Low-level design requirements like concurrency, latency, and throughput impact code writing. Use case diagrams help identify user needs. Fulfilling user requirements leads to happy customers, crucial for engineers. -Understanding low-level design requirements such as concurrency, latency, and throughput is essential for writing efficient code. -Utilizing use case diagrams to identify and fulfill user needs is crucial for ensuring customer satisfaction and success as an engineer. -Translating user requirements into classes and objects is a key step in the design process, ensuring clear APIs and efficient implementation. 57:38 Understanding the difference between 'play' and 'get video frame' APIs is crucial for designing efficient video playback systems. Consider user behavior and business use cases when merging similar APIs to streamline maintenance and improve user experience. -Differentiating between user actions like 'play' and 'get video frame' is essential for optimizing video playback functionality and enhancing user engagement. -Considering the business use cases and user behavior helps in merging APIs effectively to reduce maintenance overhead and improve overall user experience. -Designing class diagrams for video-related systems involves defining states, behaviors, and operations for entities like videos, users, and video consumption services. 1:06:10 Understanding the sequence diagram is crucial for defining the sequence of actions in a system. Authentication plays a key role in interactions between users and video services, impacting network calls and efficiency. -Importance of sequence diagram in defining actions and interactions within a system for clarity and structure. -Significance of authentication in user-video service interactions, affecting network calls and operational efficiency. 1:13:45 The video discusses defining states and behaviors of objects, emphasizing the importance of handling timestamps accurately in class diagrams and code for video-related applications. -Importance of accurately handling timestamps in class diagrams and code for video applications. Emphasizing fixing discrepancies in both places for better documentation and functionality. -Addressing the need to handle exceptions and avoid magic constants like 'plus 10' for frame time, suggesting using constants for flexibility and easy maintenance. -Discussing the variability in frame times based on video content quality and suggesting defining frame time as an object property for each frame rather than a class property. 1:21:50 The video discusses creating a database, defining classes, and manipulating data through APIs to simplify code and enable reuse in system design. It emphasizes abstracting data into objects for different use cases. -Creating a database and defining classes are crucial steps in system design to support data manipulation and API exposure for code simplification and reuse. -Abstracting data into objects with distinct state and behavior facilitates efficient data manipulation and code simplification for various use cases in system design. -The video suggests exploring free resources on design patterns and system basics before considering advanced paid sections to enhance system design knowledge.

[@jamialhasan9203]

Teaching something simple thing in complex way dose not really mean learning system design, rather knowing philosophy behind a system or process is more important.

[@tusharys9404]

I agree to this

[@aldrinseanpereira140]

Gaurav hats off to your wonderful course!

[@juffler463]

I know all this but I was doubting my self that, Is my way of system design is right. Now I am more confident thanks 🙂

[@IsxaaqAcademy]

I typed it on the search box, and you have uploaded it 5 hrs ago, Delightful!

[@chauvoluuhuong7485]

For me, it is not about SQL or noSQL It is more about: - Is it cheap? is it scaleable? at this stage of the project can I utilize my available resource? - Do we need schemaless/no schemaless, usually because of shameless, the database needs to take more space for storing and is slower at execution. Like dynamic-typed langue vs typed language. - Can I make relationship ? (typically the NoSQL is considered weak relationship, BUT YOU CAN STILL MAKE RELATIONSHIP. PLUS, BECAUSE OF SCHEMALESS YOU CAN EMBED DOCUMENT FOR MAKING THE RELATIONSHIP AND MAKING THE QUERY FASTER WITHOUT JOINING ACROSS TABLES ) - How about its built-in function? it is usually better if you make the computation on the database instead of pulling it down to the server and computing and of course, you don't have to re-develop that function - The last one, of course, which type of database is more familiar to my team

[@domisPL_01]

i believe you mean "schemas" , not "schemaless"?

[@nobytes2]

In terms of databases you really only have a few types, NoSQL, SQL, and in-memory. The brand of the db is almost irrelevant any decent engineer should know how to work with any of them.

[@jibbscat5146]

What about graph db

[@mrsbootsworkouts]

I really liked this course. it includes not just the patterns, but also connects it to the process of distilling Business Needs as an engineer. Thank you for sharing this course! Excellent point about testing the design, especially for large complex systems.

[@borisv8766]

Great video. 1:18:43 - if going with variable frame length, then, if a frame is extended with absolute start position attribute, it becomes possible to do binary search within frames array for timestamp, instead of linear iterations ( O(log n) vs O(n) ). With fixed frame length even better, instead of iterations just divide timestamp by frame length, and we have a frame index in O(1).

When he said 'if this sounds exciting to you' I had to laugh a little. I'm the only person in my life remotely interested in software engineering. My fiance is a CNA getting her RN. My dad owns a welding business. Her stepdad and brother both weld, so all in all I am the only person I know interested in it, and I get really excited about different software engineering related things, and I always feel like the oddball out. So it's nice to know other people get excited about it as well xD
