As more enterprises migrate applications to the cloud, they seek to take advantage of the frameworks, middleware, and other software tools already in their data centers, as well as the different clouds available. Today WSO2 unveiled its answer to this growing demand with the beta release of WSO2 Stratos 2.0. Newly re-architected, WSO2 Stratos 2.0 is the industry’s first foundation for implementing a platform-as-a-service (PaaS) that combines support for heterogeneous applications and service-oriented architecture (SOA) platform runtimes with native, secure multi-tenancy. WSO2 Stratos 2.0 also adds the capability to run on any cloud infrastructure, including VMware, Eucalyptus, Amazon and OpenStack.

WSO2 previewed the latest release of WSO2 Stratos at WSO2Con 2013, which runs February 13-14 in London. The company also announced that it has begun accepting customers for the WSO2 Stratos 2.0 beta program.

“Increasingly enterprises view the cloud as a platform for innovation. However, until now they’ve had to make trade-offs between using their favorite development tools and middleware or capitalizing on the multi-tenancy of a native cloud environment. With WSO2 Stratos 2.0, these organizations no longer have to compromise,” said Dr. Sanjiva Weerawarana, WSO2 founder and CEO.

Expanding the Scope of Multi-tenancy

The Stratos 2.0 approach to multi-tenancy goes beyond other PaaS environments to support multiple levels of virtualization—from standard virtual machines, via Linux Containers to intra-JVM isolation. This choice of sharing resources while providing the correct isolation level for multiple tenants is a significant factor in enabling lower costs, greater flexibility, and easier on-ramping into a private or public cloud environment.

The new tenant-aware elastic load balancer in Stratos 2.0 is a first-of-a-kind capability that allows the environment to provide highly tunable performance to different tenants, ranging from “economy class” for low priority workloads up to “private jet” mode for workloads that require dedicated resources.

Plugging in Multi-tenant Cloud Capabilities

At the heart of Version 2.0 is a new cartridge architecture for plugging software into WSO2 Stratos to take advantage of cloud-native capabilities, such as multi-tenancy, elastic scaling, self-service provisioning, metering, billing, and resource pooling, among others. As a result, WSO2 Stratos 2.0 is able to run, not only 13 WSO2 Carbon enterprise middleware products, but also a choice of frameworks, databases, and other application services.

WSO2 Stratos 2.0 also significantly enhances PaaS deployment through an integration layer that uses the popular jclouds technology to allow it to run on any infrastructure-as-a-service (IaaS) including OpenStack, VMware, Eucalyptus and CloudStack. Additionally, use of the Puppet open source tool for infrastructure deployment in this release makes it easier than ever to install and configure Stratos in a private or public cloud environment. Like all WSO2 software, WSO2 Stratos 2.0 is 100% open source and will be made available under the Apache License 2.0.
