A Performance Comparison of Popular Open Source Web Services Engines

Service Oriented Architecture (SOA) stands on the twin pillars of reusability and interoperability. Any business function that can be reused is an ideal candidate to be exposed as a service. A reusable service, until and unless implemented in an interoperable manner, isn't much use. Web Services standards provide standards-based interfaces for service description, discovery, and message definitions to invoke such services. Web Service technology has come a long way to reach enterprise-grade adoption of the core standards. Nonetheless, the process has been facilitated by Web Serv... (more)

SOA Created AJAX and Rich Internet Applications

SOA has come a long way from a concept to wide-scale adoption by the enterprise at multiple layers of IT. SOA implementation at the UI layer is the latest in SOA adoption trends. SOA has manifested itself in a number of flavors such as the creation of a rich user experience by using technology like AJAX (e.g., Google Maps), provisioning value-added services by mashing up data from multiple sources (e.g., chicagocrime.org), community-based peer-to-peer interactions (e.g., Facebook and Flickr), creating collective intelligence (e.g., Digg and del.icio.us), creating collaborative pl...
