We are considering switching servers (Windows IIS to Linux Apache) for our ColdFusion applications. Beyond meeting system requirements, does Adobe recommend one environment over another when hosting ColdFusion?
Not speaking for Adobe - I have never seen any such endorsement of one over the other. I find that a larger percentage of ColdFusion users run on Windows, but I personally use Linux when I have a choice. I think you should go with whatever environment you or your team is best suited to administer.
