Open source service-oriented architecture may be an option for companies that have to tighten their purse strings in the current economy, LinuxWorld.com writer Mike Kavis says. It doesn't require a huge cash commitment from upper management, and it allows for greater customization, even in the way it is implemented. He notes that the company can purchase an entire SOA stack from a single vendor, mix SOA components from different open source vendors or even mix open source components with proprietary ones.
Kavis points to two open source SOA vendors that offer complete stacks: MuleSource and WSO2. MuleSource, which is led by Dave Rosenberg, offers everything from the Mule enterprise service bus to Mule Galaxy, an open source SOA governance and management platform. Rosenberg told me when Galaxy first released that, it brought SOA governance to the masses.
WSO2 offers a completely free SOA platform. The company offers only one version of its products -- not a separate commercial version for businesses. Kavis notes that this approach allows customers to experience all the platform's features "without ... limitations of a community version."
