Major problem using Linux as server is the Support. As such we don't have proper support for Linux operating system. I understand that we do have lot of users and mailing list and people involved with Linux community are kind enough to share experience and solutions however, what about SLA ( Service Level Agreement)? .
That is the very reason RedHat exists! Service Level Agreement. I don't mean to come off flipent here, but that is where RedHat ES is these days, and from what I hear their support is top notch!
