J2EE performance, reliability and complexity

.88888 - The Fabled "Five Eights" of J2EE Availability: "The bottom line is that way too many of the J2EE applications deployed in enterprises today have absolutely dismal performance. To put it bluntly, our applications stink! You can completely forget all the haughty talk about "five nines" reliability. The average availability of the J2EE applications referenced in the survey is just 88%. That's right - we're talking the fabled "five eights" of J2EE availability. Half of the responses show overall app availability (an application's ability to service user requests) below 96%, which means almost seven hours of downtime per week! That's seven hours of pain, lost revenue, confusion, and bad news for Java. Not only that, but half the responses are indicating even less than 96% availability."
