TL;DR — Imgur/Image Hosting

Design an image hosting and sharing platform like Imgur where users can upload images, which are then processed, stored, and served globally with minimal latency. The platform must handle high upload volumes, generate multiple thumbnail sizes on the fly, and serve billions of image requests per day through a CDN. Key features: Upload images (JPEG, PNG, GIF, WebP) up to 20MB, anonymous or authenticated. Generate multiple thumbnail sizes automatically (small, medium, large, original).
