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.

Sia

Decentralized storage service Sia has been around since 2014, originally incorporated as Nebulous Inc.

Sia launched their Cryptocurrency by the end of 2015. Early investors have since seen an incredible increase of the currencies value by over 18.000 times the initial price. Before launching their Cryptocurrency a Whitepaper was published with details on how Nebulous/Sia expected to see the network grow, describing their storage capacity algorithm and more.

Sia uses smart contracts to ensure SLAs on uptime, pricing and more. Sia is open source and written in Golang.

Sia is one of the storage backends for Filebase. Investors of Sia include Procyon Ventures and Raptor Group
