Banks (Bank of America, PNC, American Express, MasterCard, Visa, Discover) use Web Services, WebSphere Message Queues, and Enterprise Service Bus'. I'm sure PHP or ASP.NET is thrown in someplace, but the bulk of development is using ESBs since the COBOL logic on the mainframes drive the business but the WebSphere Application Servers need to talk to them. IBM Integration Bus uses PHP,
Java, and ESQL. It can use ASP.NET but having been at all those sites listed previously, I know for a fact that they do not use ASP.NET on a daily basis to do the heavy lifting of their development work.
