WSO2 puts its SOA platform in Amazon’s cloud

By David Worthington

November 16, 2009 — SOA infrastructure software maker WSO2 has turned its attention toward cloud computing by releasing virtual editions of its products that run on Amazon EC2, as well as a service gateway for accessing resources that reside behind the firewall.

Cloud computing is part of the same trend as SOA, said WSO2 chairman and CEO Sanjiva Weerawarana. "Service-oriented architecture is about connecting applications together in a loosely coupled manner,” he said. Cloud computing is another dimension to that aspect of SOA as a way of providing couplings between applications and how those applications are deployed and bound to hardware, he added.

As a first step toward the cloud, WSO2 has ported its SOA platform to Amazon's Elastic Compute Cloud (EC2) as virtual appliances. "It's easier to run. Developers do not install or configure machines," Weerawarana said.

Those offerings will include virtualized business process servers, business activity monitors, data services servers, an enterprise service bus, identity services, governance registries, a mashup server and presentation services, according to Weerawarana.

WSO2 presently provides all of the services, except the business activity monitor and presentation services. The source code for the WSO2 cloud platform is offered to customers, and customers retain ownership of data.

Pricing is in addition to standard EC2 pricing with a rate of US$1 per CPU hour for small machines, $1.50 for medium machines, and $2 for large machines. WSO2 plans to support VMware and other cloud environments in the future, said Weerawarana.

A separate appliance called WSO2 Service Accelerator provides a front end for existing SOA infrastructure. It features a C++ stack and is intended to decouple service performance from existing SOA infrastructure, Weerawarana said. "It offers better performance than straight Java infrastructure."

A gateway connects Amazon, Google Apps and Salesforce cloud services to enterprise data that exists in private data centers. It provides API protection, outsourcing for computations, private data access, and service firewalling, and it integrates with directories and security infrastructures, according to the company.

"It is for scenarios where the cloud business logic needs to access data in the enterprise," Weerawarana explained.

WSO2 is also providing middleware to help developers build multi-tenant services. Its service registry provides data management for applications. Identity, security and service management tools will become available next year, Weerawarana said.

The middleware components are integrated and built according to the OSGi specification for modularity.

Lastly, a service extends the functionality of WSO2's governance registry for SOA to the cloud. Each tenant can have his or her own theme and manage a user community, according to the company. Pricing will be based on volume of transactions.
