Applications:
WEB SERVICES TO DOMINATE ENTERPRISE APPLICATION INTEGRATION
According to Evans Data Corp's new Fall 2004 Web Services/SOA Development
Survey, four in 10 Web Services developers feel that Web Services either
"absolutely" or "probably" diminish the need for Enterprise Application
Integration. Only 10 percent feel that Web Services "absolutely" does not
diminish the need for EAI. In addition, six in 10 Web Services developers
believe that Web Services can significantly or somewhat lower costs to
implement standard EAI implementations.
"EAI used to be a big-budget project that required the building of an entire
middleware layer of composite applications that replicated legacy processes.
With the standardization that Web Services brings, applications can be linked
with fewer lines of code, and often within a much shorter time frame," said
Joe McKendrick, an analyst with Evans Data. "The savings potential of Web
Services is enormous."
Other findings from the October 2004 survey of more than 400 developers
currently involved with Web Services:
- The top three types of services being developed for Web Services are:
Business process management; Data management, cleansing and synchronization
tools; and e-commerce applications.
- Seventeen percent of survey respondents are using third party consulting to
help with Web Services projects and another 14 percent plan to use a third
party consultant in the next year. The Web Services areas in need of the most
third party consulting help are: Security; Design and Development; and
Interfacing to legacy systems.
- Web service development budgets are growing. By next year one of five Web
Services developers expect to be devoting most of their IT budgets to Web
Services initiatives.
- When asked about the biggest obstacle to Web Services, 20 percent of
respondents indicated that interfacing to legacy code is the biggest hurdle to
Web Services implementations; a year ago only 8 percent considered this a
problem.
