Deploying and migrating JavaEE applications is hard work. Specifically, it's work that's error-prone, repetitive, and time consuming because of the complexity of setting up or tweaking Web application servers. The result is lost man/hours, soaring costs, and potential problems associated with hidden or unseen configuration issues that might pop up at a later time. Furthermore the situation is often muddied by the 'fog of war' - technical personnel and their managers don't really have any easy way to take an accurate snapshot of current application server configurations, and no easy way to make decisions regarding those assets and how they can (or can't) support an enterprise's line of business.
