"Frankly, if I were an enterprise architect today, and I were genuinely concerned about development costs, agility, and extensibility, I’d be looking to solve everything I possibly could with dynamic languages and REST, and specifically the HTTP variety of REST. I’d avoid ESBs and the typical enterprise middleware frameworks unless I had a problem that really required them (see below). I’d also try to totally avoid SOAP and WS-*."
Завершая очередной проект, где несколько месяцев было потрачено на интеграцию через Web Services и SOAP (куда ж мы сегодня без мыла?), я все больше склоняюсь к тому, о чем пишет Стив. Особенно после того, как набрел на замечательную книжку "RESTful Web Services".
