Reuse Engineering for SOA

An anonymous reader writes "In most development organizations, software reuse occurs on a regular basis in at least an ad hoc manner. Code is shared across projects in an informal manner. SOA provides the mechanism for more formal reuse. So what are the issues? This article examines some of the challenges associated with the creation and usage of reusable services."

SOA - Service-Oriented Architecture

Re:Software reuse.

[cpn2000]

I agree that code re-use within organizations is over-rated, but code re-use in the broader scheme of things is absolutely there, and growing. Over the years of doing server-side Java programming, I have come to increasingly rely on the various apache (and other such Open Source) projects to provide everything from XML parsers, to IDEs.

On the other hand code re-use within organizations is rare, but I think that is mostly a process issue, not a technology one. In my experience product development companies have much better processes to foster such re-use, while non-software companies, where the IT division is more a necessary evil, rather than an asset, do not.

Re:Software use and reuse

[Bill Privatus]

This is the longest rant I think I've ever seen that was composed based on zero knowledge of the technical subject at hand, but rather on some kind of on-the-fly interpretation of the three words "service" "oriented" and "architecture" used in juxtaposition.

Your points:

1. [...]being "service oriented" is roughly as new as dirt.

   See above.

2. how in the world this would relate to software reuse

   SOA makes software reuse not only easy but unavoidable - through tooling. See my other posts here for other thoughts in this vein, including use of ESB (Enterprise Service Bus).

3. ...they haven't really told you anything about how to facilitate reuse in general, or how SOA is supposed to contribute to that...

   Interesting. What else have you tried to read besides this sales-oriented (I call it marketecture ) web page? Any actual technical articles?

Here, try these:
