WSO2 today announced the debut of the WSO2 StratosLive platform as a service (PaaS) and the launch of WSO2 Stratos 1.5, the newest release of WSO2’s open-source cloud middleware platform software. Together, they provide comprehensive cloud middleware solutions for enabling service-oriented architecture (SOA) and composite application development and deployment in the cloud.

The Palo Alto, Calif., company offers a complete PaaS both as on-premise software and as a hosted service, running the same production-ready code wherever it best suits customers’ privacy, service-level agreement (SLA), and deployment requirements. [Disclosure: WSO2 is a sponsor of BriefingsDirect podcasts.]

StratosLive provides a complete enterprise deployment and integration platform, including application server, enterprise service bus (ESB), database, identity server, governance registry, business process manager, portal server and more.

Stratos provides the same capabilities to organizations that want the benefits of a PaaS running on their own premises. It builds on and extends WSO2's Carbon enterprise middleware platform by taking the Carbon code and adding cloud functionality for self-service provisioning, multi-tenancy, metering, and elastic scaling, among others.

All Carbon products, including the latest features from the recent Carbon 3.2 platform release, are available both as part of the Stratos cloud middleware platform and as cloud-hosted versions with instant provisioning on the StratosLive public PaaS. WSO2's approach enables developers to migrate their applications and services between on-premise servers, a private PaaS, a public PaaS, and hybrid cloud environments, providing deployment flexibility.

“The cloud is a compelling platform for enabling enterprises to combine the agility they’ve gained by employing SOAs and composite applications with an extended reach and greater cost efficiencies,” said Dr. Sanjiva Weerawarana, WSO2 founder and CEO. “At WSO2, we’re delivering on this promise by providing the only truly open and complete PaaS available today with our WSO2 StratosLive middleware PaaS and WSO2 Stratos 1.5 cloud middleware platform.”

Four new products
The launch of StratosLive and Stratos 1.5, adds four new cloud middleware products:

  • Data as a Service provides both SQL and NoSQL databases to users based on both MySQL and Apache Cassandra. This allows users to self-provision a database in the cloud and to choose the right model for their applications.
  • Complex Event Processing as a Service is the full multi-tenant cloud version of CEP Server, which launched in June 2011 and supports multiple CEP engines, including Drools Fusion and Esper, to enable complex event processing and event stream analysis.
  • Message Broker as a Service is the full multi-tenant cloud version of Message Broker, which launched in June 2011 and supports message queuing and publish-subscribe to enable message-driven and event-driven solutions in the enterprise. It uses Apache Qpid as the core messaging engine to implement the Advanced Message Queuing Protocol (AMQP) standard.
  • Cloud Services Gateway (CSG), first launched as a separate single-tenant product, is now a fully multi-tenant product within Stratos and StratosLive.

With StratosLive and Stratos, central cloud features are built directly into the core platform—including multi-tenancy, automatic metering and monitoring, auto-scaling, centralized governance and identity management, and single sign-on. The Cloud Manager in StratosLive and Stratos offers point-and-click simplicity for configuring and provisioning middleware services, so developers can get started immediately and focus on the business logic, rather than configuring and deploying software systems.

Additionally, the Stratos cloud middleware platform features an integration layer that allows it to install onto any existing cloud infrastructure such as Eucalyptus, Ubuntu Enterprise Cloud, Amazon Elastic Computing Cloud (EC2), and VMware ESX. Enterprises are never locked into a specific infrastructure provider or platform.

The availability of StratosLive and Stratos 1.5 brings several new core platform enhancements:

  • Software-as-a-service (SaaS) Web application support
  • Google Apps integration
  • Metering and usage throttling
  • Billing
  • Multi-tenant logging

WSO2 StratosLive and WSO2 Stratos 1.5 are available today. Released under the Apache License 2.0, they do not carry any licensing fees. Production support for the Stratos starts at $24,000 per year. StratosLive middleware PaaS is available at three paid subscription levels: SMB, Professional, and Enterprise, as well as a free demo subscription.
