I didn’t know that Java Web Start technology has already been deployed (to be more precise, can de deployed) to serve the mission critical enterprise application until I read Hans Muller (CTO of Sun’s Desktop Division)
Weblog.
FIDUCIA is the largest IT-Fullservice provider for the German cooperative Banks. They provide comprehensive software solutions to 920 banks. The service includes both desktop and server side applications and they run
data centers for the latter. Managing about 38 million accounts (2.3 billion transactions/year!) requires lots of big iron. They've got nearly 1000 server machines and 138 terabytes of (SAN) storage. The desktop software is deployed on 106,500 PC desktops.
And it's all Java. Desktop and server. All Java.
I’m glad to say that other than browser-based web application and traditional client-server application, we now have another good choice.
