Make your own cloud

WSO2 launch pick-and-mix cloud platform in Stratos 2.0

Room for another cloud platform update this month? WSO2 are the latest in line to release a new iteration of their enterprise PaaS, in Stratos 2.0.

The major update introduces a cartridge-based architecture, allowing developers to deploy multiple runtimes in various languages and services. Initial plug-ins include PHP, MySQL and Tomcat, as well as the portfolio of WSO2 Carbon Middleware products. This includes the company’s own message broker, enterprise service bus, API manager and application server.


The team behind the project claim that Stratos combines “support for heterogeneous applications and SOA platforms” with “native, secure multi-tenancy.” They also encourage developers to create their own cartridges. Like the rest of WSO2’s projects, Stratos is 100% open sourced under an Apache 2.0 license.

Another new aspect of Stratos is the ability to run your custom PaaS across popular cloud infrastructure platforms such as SUSE Cloud, OpenStack Eucalyptus and Amazon EC2. This is possible through the use of jclouds - the open source portable cloud library which has recently appeared in the Apache Incubator. With this library, Stratos is able to pick between 30 different infrastructure and switch across multiple options, which could prove to be a decisive selling point for enterprises looking for flexibility.

Stratos 2.0 also contains a new “tenant-aware” elastic load balancer, meaning users can tune performance of workloads, from low priority to those that require dedicated resources. The PaaS also uses automation management tool Puppet for private or public deployment, which could seen as an friendly method of introducing the platform to system administrators.

Stratos’ plug-in and play-style cloud platform could be another contender in the already crowded field. It is available to download now at Stratos’ website.

Stratos featured in last month’s JAX Magazine. You can download that issue here to learn more about the project, with an article written by WSO2’s CTO Paul Fremantle.
