FROM THE EDITORS

That Old Time Religion

The QCon conference in San Francisco was an inaugural affair—but the religious warfare displayed at the event harkens back to every passionate my-way-or-the-highway fight in our market, whether it's Mac vs. Windows, Java vs. .NET, native code vs. managed environment, compiler vs. interpreter, ASCII vs. EBCDIC, hex vs. octal, or big-endian vs. little-endian. WS-* vs. REST is just the latest battleground.

On one side, the WS-* family of Web services specifications is the very epitome of a larger, well-thought-out specification that attempts to build contingencies for every possible SOA scenario. There are dozens of WS-* specifications, many of which are already obsolete or obsolescent. Many of them smack of proprietary vendor shenanigans, while others have won broad acceptance. Nobody would dispute, however, that the plethora of overlapping WS-* specs present considerable complexity for Web services and SOA deployments. Even keeping up with WS-*'s many players can be a full-time job.

On the other side, the ultra-simplistic and totally free REST (Representational State Transfer) architecture forgoes all that XML and security complexity in favor of encoding state information into the URLs being transferred back and forth across the network. REST is becoming wildly popular, in large part because it's easy to understand and implement. Google Maps adheres to this architecture, and thousands of mashups can attest to its considerable power.

When you have two ways of solving a problem, and those ways are philosophically incompatible with each other, a religious war often appears. And indeed it has, as the civil-but-pointed discussions at QCon demonstrated.

The last thing we need right now, during this fragile and confusing chapter in software, is another holy war. As developers spend their days learning how to code multiple threads and cope with 64-bit processors, they shouldn't have to become embroiled in a drawn-out war of attrition over Web services standards.

When it comes right down to it, digesting REST should be a very simple affair for any WS-* group.
