Descriptions

Azure Storage

Microsoft Azure Cloud Storage Microsoft’s answer to their cloud competitor Amazon is finally here. Microsoft has a wide range of storage solutions, providing SaaS (software as a service), PaaS (platform as a service ) and IaaS (infrastructure as a service). Azure supports a great variety of programming languages, tools, and frameworks, ranging from Microsoft-specific to Linux, or other third-party software and systems.

In the table below we’ll look at the Hot Access Tier, as this is the most commonly used storage tier for online usage.

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.
