With the promotion of Apache Stratos to a top-level project of the open source organization, one of the first to sign on to build platform-as-a-service (PaaS) offerings around the project is WSO2. The company announced at WSO2Con Europe 2014 that it was launching WSO2 Private PaaS 4.0, which it described as the first enterprise-grade PaaS based on the Stratos 4.0 framework that was released earlier in June.
The new private PaaS offering was designed to provide a cartridge-based architecture that enables developers to plug in heterogeneous applications and service-oriented architecture (SOA) platform runtimes to take advantage of native, secure multi-tenancy. WSO2 noted that the multi-tenancy capabilities are available at the in-container level, enabling deeper multi-level tenancy that is required to support software-as-a-service (SaaS) applications.
The latest version of the WSO2 PaaS has been updated with several new features, including:
Real-time auto-scaling enabled by complex event processing (CEP) for more powerful analysis of the runtime environment.
Smart policies for deploying cartridges, auto-scaling, and partitioning.
"A year ago we donated our PaaS foundation to Apache to support the open source community in developing PaaS solutions that address the industry's need for robust multi-tenancy and support for the heterogeneous environments that power enterprises," said Paul Fremantle, WSO2 co-founder and CTO, in a prepared statement. "The result is Apache Stratos 4.0, which adds innovative firsts in intelligently managing cloud capacity and which we are proud to make available with the launch of our WSO2 Private PaaS 4.0."
The WSO2 announcement gives further credence to the importance of an open source PaaS foundation like Apache Stratos, and it's likely there will be more announcements from other vendors and cloud providers related to Stratos over the coming weeks.
