Amazon S3
World’s biggest Cloud Storage Provider. Amazon, traditionally an online book store, has put a target on the cloud compute space when it shifted its focus to Amazon Web Services (AWS) in 2006. E-Commerce competition was tough, but public cloud companies back then were scarce, and usability and user friendly products were a long way from being invented.
Amazon’s reign on cloud computing has left its mark in public cloud-land. Competitors have trouble keeping up, if they even get to a point of feature-parity at all. With Amazon’s S3 storage being one of the first, it has basically dictated a standard for the public cloud’s blob storage protocol.
Needless to say, Amazon invented the S3 (Simple Storage Service) standard.
