Question

What language is Amazon's AWS Management Console written?

Answer 1

Like most web applications, the Amazon AWS Management Console is written in the client-side languages Javascript, CSS, and HTML. On the server side, they seem to use pack:tag (just look at the X-Powered-By response header), which is a JSP-compatible library, so I assume they use Java there.

Answer 2

Java on the backend (via AWS Flow). The frontend was built using Javascript/CSS using the YUI framework.
