I'm trying to catch up on reading this weekend and ran across this James Govenor gem:
"Big SOA with reg/rep and so on- who needs it? Who is using it? Remember UDDI? It was designed to handle WSDL complexity. But very few organisations needed it. UDDI was designed to offer extreme configurability. Who most likes extreme configurability? Consultants."
Being a consultant I couldn't agree with him more. As long as the standards world keeps on publishing inch-thick standards there will be plenty of money to be made.
