Complete S3/Object Storage System Design Explained | Interview Prep #s3 #objectstorage #systemdesign

In this video, I provide a complete system design explanation of Amazon S3 and Azure Blob Storage, covering everything from basic concepts to advanced internal architecture, with a strong focus on interview preparation. What You Will Learn: Introduction to Object Storage: Differences between Block, File, and Object Storage Core Features of S3 & Blob Storage: Scalability, High Availability, Durability, and Reliability Key Operations: Bucket creation, object upload, and download Data Write & Replication Trade-offs: Speed vs safety in distributed storage systems Write-Ahead Log (WAL) Mechanism: Efficient storage of small files and immutability Metadata Management & Sharding: Composite keys, shard-aware design, and load balancing Object Retrieval Flow: Metadata lookup and WAL-based reads Data Integrity: Checksums, immutable objects, versioning, and replication with integrity checks Handling Large Files: Multipart upload, parallel uploads, retries, and range downloads Automatic Object Expiration: Lifecycle rules and TTL management Efficient Object Listing: Shard-aware keyset pagination for billions of objects Best Practices for System Design: How S3/Blob ensures durability, availability, and performance #amazons3 #s3 #objectstorage #azure #azurestorage #systemdesigninterview #systemdesign #distributedsystems #aws #awss3 #scalablearchitecture #datastorage #interview #sde #softwareengineer #software #techinterview #cloud #system #computerscience #softwaredevelopment #softwareskills #softwarejobs #faang #faangpreparation #faangcodinginterviewpreparation #faanginterview #bitstorm
