In this video, we break down the **system design of a Web Crawler**, one of the most commonly asked questions in system design interviews. A web crawler is the backbone of search engines like Google, enabling large-scale indexing of the internet. In this video, we’ll design a scalable, distributed web crawler from scratch and understand how it handles millions (or billions) of URLs efficiently. 🚀 What you'll learn: • What is a Web Crawler and how it works • Key components: URL Frontier, DNS Resolver, Fetcher, Parser, Storage • Handling scalability and distributed crawling • Politeness & rate limiting • Avoiding duplicate content using hashing • Fault tolerance and retries • Data storage and indexing basics 💡 This video is perfect for: • System Design Interviews (SDE2, SDE3, Staff roles) • Backend Engineers • Anyone preparing for FAANG/Top Tech Companies If you found this helpful, don’t forget to like, share, and subscribe for more system design content! #SystemDesign #WebCrawler #SystemDesignInterview #ScalableSystems #DistributedSystems #BackendEngineering #TechWithTanya #SystemDesign #WebCrawler #SystemDesignInterview #DistributedSystems #ScalableSystems #BackendDesign #TechInterview #SoftwareEngineering #FAANGPrep #HighLevelDesign #LowLevelDesign #CodingInterview #BackendDeveloper #SystemArchitecture #TechWithTanya Keywords [web crawler system design, web crawler architecture, system design interview web crawler, distributed web crawler design, scalable crawler design, how google crawler works, search engine crawler architecture, system design tutorial, backend system design, distributed systems interview, url frontier design, crawler scalability, web scraping architecture, crawling vs scraping, system design explained, tech with tanya]
