The highly regarded Gartner’s chief fellow and group VP Daryl Plummer has a well written article in the current issue of optimize magazine titled, "Web Services At A Crossroads". He points out the SOA users fall into two camps : One group advocates using Web services to build complex internal systems known as enterprise service-oriented architectures (SOAs), while the other one seeks to use emerging Web technologies in tandem with Web services to create flexible external applications. Their divergent approaches each require different organizational skill sets. He points out to wasted efforts in trying to force web services to deliver enterprise-level capabilities they were never intended to handle. He puts across some impressive statistics : only 20% of all enterprise systems built today require the kind of robustness that standards-based web services provide & fewer than 30% of IT groups have the resources to implement all the standards that truly enterprise-capable Web services will require. Worse, most of the standards are nowhere near ready to be used consistently by mainstream IT. He adds, web technologies groups are now forcing the acknowledgment that web services will indeed use mechanisms other than SOAP, WSDL, or even Universal Description, Discovery, and Integration (UDDI). Instead, standards such as Plain Old XML (POX) over HTTP and Representational State Transfer (REST) are asserting themselves as legitimate and very credible ways of delivering on the value proposition of Web services.
