AWS S3 turns 20 and reaches 'hundreds of exabytes'

"The code you wrote for S3 in 2006 still works today, unchanged. Your data went through 20 years of innovation and technical advances. We migrated the infrastructure through multiple generations of disks and storage systems. All the code to handle a request has been rewritten. But the data you stored 20 years ago is still available today, and we've maintained complete API backward compatibility."

"S3 stores more than 500 trillion objects and serves more than 200 million requests per second globally across hundreds of exabytes of data in 123 Availability Zones in 39 AWS Regions."

"The S3 API has been adopted and used as a reference point across the storage industry. Multiple vendors now offer S3 compatible storage tools and systems, implementing the same API patterns and conventions."

Amazon S3 marked its 20th anniversary on March 14, 2006, evolving from modest beginnings with approximately one petabyte of storage across 400 nodes to a massive global infrastructure storing over 500 trillion objects and serving 200 million requests per second across 123 Availability Zones in 39 AWS Regions. The service's most significant achievement is its consistency and backward compatibility—code written for S3 in 2006 remains functional today without modification. AWS has continuously upgraded underlying infrastructure through multiple generations of storage systems while preserving complete API compatibility. The S3 API has become an industry standard, adopted by multiple vendors offering S3-compatible storage solutions, establishing S3 as a reference point for storage technology across the industry.
