Letter to the Editor: Reusability is Fundamental

To the Editor:

The June 19 Viewpoint article entitled "Building Software with Blocks," describes an important evolution in software development and deployment. Long-standing objectives have been: ever-faster deployment and greater leverage of the investment through reusability.

Service-oriented architecture is the next evolutionary step towards these objectives. The independence of the services and the resulting reusability is fundamental.

I like to think about this new software architecture approach as similar to how the iPod has changed the music world. When you download a song you can use it in an endless number of playlists that have a different purpose (commuting, exercising, etc.). Prior to iPods you bought a CD or vinyl and the song was "stuck" inside the media.

Similarly - with SOA, applications can be reused and re-combined for a variety of purposes.George Ravich
