Why do we need RESTful Web Services?

Question

I\'m going to learn RESTful web services (it\'s better to say that I\'ll have to do this because it\'s a part of CS master degree program).

I\'ve read some info in

Answer 1

REST was kicked off, to my knowledge, by Roy Fielding's dissertation Architectural Styles and the Design of Network-based Software Architectures, which is worth a read if you haven't looked at it.

At the top of the dissertation is a quote:

Almost everybody feels at peace with nature: listening to the ocean waves against the shore, by a still lake, in a field of grass, on a windblown heath. One day, when we have learned the timeless way again, we shall feel the same about our towns, and we shall feel as much at peace in them, as we do today walking by the ocean, or stretched out in the long grass of a meadow.

— Christopher Alexander, The Timeless Way of Building (1979)

And that really does sum it up there. REST is in many ways more elegant.

SOAP is a protocol on top of HTTP, so it bypasses a lot of HTTP conventions to build new conventions in SOAP, and is in a number of ways redundant with HTTP. HTTP, however, is more than sufficient for retreiving, searching, writing, and deleting information via HTTP, and that's a lot of what REST is. Because REST is built with HTTP instead of on top of it, it also means that software that wants to integrate with it (such as a web browser) does not need to understand SOAP to do so, just HTTP, which has to be the most widely understood and integrated-with protocol in use at this point.
