Expedia SDE-3 explains Cloud Storage & Sync System (like google drive, dropbox etc.)

In this video, we take a deep dive into the core components involved in designing a scalable 𝗖𝗹𝗼𝘂𝗱 𝗦𝘁𝗼𝗿𝗮𝗴𝗲 & 𝗙𝗶𝗹𝗲 𝗦𝘆𝗻𝗰 𝗦𝘆𝘀𝘁𝗲𝗺 (𝗹𝗶𝗸𝗲 𝗚𝗼𝗼𝗴𝗹𝗲 𝗗𝗿𝗶𝘃𝗲, 𝗗𝗿𝗼𝗽𝗯𝗼𝘅, 𝗲𝘁𝗰.) Covered below topics: The key building blocks of a large-scale distributed file storage system. A detailed breakdown of the two critical flows: file upload & chunking and real-time sync across devices. Database schema design for storing file metadata, version history, chunks, checksum, etc. Managing a local storage and local metadata DB by the client app alongside remote storage. Use of checksums and fingerprinting to optimize the upload/download flow. How chunking works and how the checksum is applied to those chunks. Dramatically reduce bandwidth usage by chunking and delta-sync. High-level design of all these components tied together.
