Tim Bray who invented XML among other things, takes a stand against Web Services. Here’s what he says:
No matter how hard I try, I still think the WS-* stack is bloated, opaque, and insanely complex. I think it’s going to be hard to understand, hard to implement, hard to interoperate, and hard to secure.
I look at Google and Amazon and EBay and Salesforce and see them doing tens of millions of transactions a day involving pumping XML back and forth over HTTP, and I can’t help noticing that they don’t seem to need much WS-apparatus.
I’m deeply suspicious of “standards” built by committees in advance of industry experience, and I’m deeply suspicious of Microsoft and IBM, and I’m deeply suspicious of multiple layers of abstraction that try to get between me and the messages full of angle-bracketed text that I push around to get work done.
It should be noted that Tim has recently taken a job with Sun Microsystems. His current employer is very actively involved in Web Services, so I believe he takes this stand despite the current interest of his employer.
