Now, in order to leapfrog IIS and claim the No. 2 spot for itself, Nginx (pronounced Engine-X) has announced the availability of Nginx Plus, a fully supported version of the server program. This new version comes not only with professional support services, which have been available since February 2012, but with additional features. The commercial version has been developed and supported by Nginx’s core engineering team and is available on a subscription basis starting at $1,350 per instance per year.
