Learn System Design

Send us a text Web Crawler DesignsCan a simple idea like building a web crawler teach you the intricacies of system design? Join me, Ben Kitchell, as we uncover this fascinating intersection. Returning from a brief pause, I'm eager to guide you through the essential building blocks of a web crawler, from queuing seed URLs to parsing new links autonomously. These basic functionalities are your gateway to creating a minimum viable product or acing that system design interview. You’ll gain insights into potential extensions like scheduled crawling and page prioritization, ensuring a strong foundation for tackling real-world challenges.Managing a billion URLs a month is no small feat, and scaling such a system requires meticulous planning. We’ll break down the daunting numbers into digestible pieces, exploring how to efficiently store six petabytes of data annually. By examining different database models, you’ll learn how to handle URLs, track visit timestamps, and keep data searchable. The focus is on creating a robust system that not only scales but does so in a way that meets evolving demands without compromising on performance.Navigating the complexities of designing a web crawler means making critical decisions about data storage and system architecture. We’ll weigh the benefits of using cloud storage solutions like AWS S3 and Azure Blob Storage against maintaining dedicated servers. Discover the role of REST APIs in seamless user and service interactions, and explore search functionalities using Cassandra, Amazon Athena, or Google’s BigQuery. Flexibility and foresight are key as we build systems that adapt to future needs.

Send us a textUnlock the secrets of API design and elevate your system design skills with our latest episode featuring me, Benny Kitchell. Explore the pivotal role APIs play in system design interviews and real-world development, where they act like the seamless communication between waiters, cooks, and customers in a restaurant. Learn how to craft APIs that are tailored to both internal and external developers by understanding their specific needs and objectives, ensuring a smooth and efficient user experience.We also shine a light on the critical aspects of designing API routes. Understanding user needs and addressing core problems are the bedrock of effective API design. By focusing on functional and non-functional requirements, you'll be equipped to create API routes that meet real-world demands. Discover the importance of API versioning through our Spotify example, where future-proofing your design becomes crucial in maintaining user satisfaction and facilitating seamless updates.Finally, we delve into the world of real-time data transfer, examining both synchronous and asynchronous communication methods. From the traditional request-response model to the innovative use of WebSockets for instantaneous data exchanges, we break down the strengths and limitations of each approach. Equip yourself with the knowledge to choose the best method for your client-server interactions, ensuring your system design is robust, flexible, and ready for any challenge.Support the showDedicated to the memory of Crystal Rose.Email me at [email protected] the free Discord Consider supporting us on PatreonSpecial thanks to Aimless Orbiter for the wonderful music.Please consider giving us a rating on ITunes or wherever you listen to new episodes.
