You've probably heard of AWS Simple Storage Service (Amazon S3), which allows you to store objects in buckets.
The AWS S3 API was the original blob storage interface, and many storage providers and technology companies have reverse-engineered or emulated it to ensure compatibility.
Some notable examples include services like Cloudflare R2 and Backblaze B2, but there are countless others, as you'll see below.
