Ror on the premise

Hello all,
I have been using ror for a while and I really like the it. All of the
projects have been web-based applications. I an tasked to build a new
product that is installed on the premise (on a customer’s server) and I
thinking of using ror for it instead of java.

  • Has anyone had such experience?
  • What are the drawbacks of such approach?

thanks in advance.
