Summary

In this hour, we've discussed what issues currently affect Web services. We've looked at how some of the underlying technical foundations could be an issue for Web services.

We then discussed some of the performance problems associated with this technology. We saw how the fact that Web services rely on nonpersistent connections found in HTTP can be a performance concern and how the conversion of data into and out of XML can slow down processing.

Next, we examined some issues that exist because of present limitations of the specifications and standards. We saw how various vendors have come up with work-around solutions that are nonportable and thus should be avoided.

Finally, we discussed some of the issues regarding the young age of Web services technologies and how this relatively young solution can cause staffing problems.

By keeping these points in mind, a proper choice can be made between a Web services–based solution and other ones.
