Object Storage
ELI5 — The Vibe Check
Object storage treats files as 'objects' — each one gets a unique key (like a URL) and is stored with its data and metadata. Unlike a folder system, there's no hierarchy — just a flat list of keys in a bucket. It's infinitely scalable and perfect for storing images, backups, and static assets.
Real Talk
Object storage is a data storage architecture where data is stored as discrete units (objects) containing the data, metadata, and a unique identifier. Unlike block or file storage, it's accessed via HTTP APIs. Highly durable and scalable. Examples: S3, GCS, Azure Blob, Cloudflare R2.
