The main benefit is that it provides an application server for web applications to run in, which makes them more reliable than other servers out there like Apache Tomcat or Jetty (which I used before). It's very easy-to use with good documentation as well so you don't need much time learning how this product works under hood! Nothing really specific if we compare against our previous solution of JBoss AS 7/8 but maybe something can be improved upon? Maybe better performance when running multiple threads simultaneously - even though my tests show otherwise right now?! So far everything looks great from what i've seen during testing period till date :).
