WSO2’s DIY cloud Stratos welcomed into Apache Incubator

 

Swiftly after releasing the new architecture behind their cloud platform, WSO2 have pushed Stratos to the Apache Incubator.

The polyglot PaaS framework, which got a bumper 2.0 release last Thursday, provides the raw components for developers to build their own cloud platform. The donation allows WSO2 to provide commercial support of the project and still retain a level of creative control, with the majority of the committer team formed from Stratos Core developers.

The main intention with the move is to open the platform up to external contributors. Developers from Cisco, SUSE and even NASA Jet Propulsion Laboratory have already professed an interest in the project, appearing on the initial committer list. Intriguingly though, fellow cloud companies are signing up, with Citrix and Engine Yard also present on the list.

In 2012, Citrix handed off IaaS project CloudStack to the same foundation. Perhaps their backing suggests they are about to wade into the PaaS space? For Engine Yard, their interest could indicate intent to expand. Their experience with multi-tenancy and polyglot environments should prove invaluable to a cloud platform making its first steps however.


Stratos is comprised of four main layers. The newly added cartridge-based architecture at the top allows developers to pick and choose between frameworks and systems. So far, WSO2 have added cartridges for languages (Java and PHP), databases such as MySQL and servers (Tomcat and Jetty).

Underpinning the entire operation is a IaaS-agnostic layer based on fellow Apache Incubator project jclouds, the portable cloud library that can switch between infrastructures. Stratos also contains a controller that automates and monitors IaaS runtimes, as well as deploying workloads. Another layer provides essential cloud services such as security, logging and storage.

WSO2 will continue to offer commercial support packages for Stratos, including the public PaaS based on the technology, StratosLive. These products will be rebranded to avoid confusion with the Apache-led vehicle.

The move across to a neutral foundation makes sense for a ‘make your own cloud’ project that wants to collaborate with various communities. While Stratos has always been open source, being housed under the Apache Foundation should give it a touch more visibility. WSO2 have realised that for a cloud platform to get recognition then the door needs to be opened further to outside influence.
