A co-worker pointed me towards this ZDNet story about an online casino which chose to move to J2EE from their legacy ASP-based application. Here are a couple of interesting tidbits from the article:

The betting exchange has been slowly ramping up its new site over the last few weeks and plans to retire the old ASP-based presence on Monday, 13 September. Betfair claims to have around 250,000 customers placing around 300 bets per second.

He claimed that the company evaluated building the site around .Net and J2EE and carried out an exhaustive comparison at the beginning of the project. “Ultimately, we chose J2EE due to its proven enterprise track record, security, and maintainability. .Net offered faster development and performance, but for a mission-critical, 24×7 site such as Betfair.com, we chose the proven, secure technology.”

One has to wonder, did they switch to Unix or Linux during this process as well?
