Descriptions

Openstack Swift

Openstack’s founders, Rackspace and NASA, have created this platform with (public) cloud in mind.

Openstack is completely opensource and freely availalble under the Apache License. Meaning, you’re free to spin up your own cloud using their software. Openstack’s storage solution (Swift) is pluggable to be s3 compatible.

Openstack has many providers offering up their hardware on the openstack IaaS layer. To name a few: Canonical’s Ubuntu Bootstack and TATA’s managed infra services

Openstack’s pluggability is where its true power lies. Its sourcecode is written in Python and actively maintained. They have many performance and security enhancements, as well as plugins ready to be installed.

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.
