That doesn't make sense. The larger the organization, the more often they have large system administrator teams. In fact, most large organizations have compliance requirements, which often map people with proper skills to proper titles and responsibilities in order to get the correct liability protection.

I can not imagine Google allowing some junior programmer to setup a little closet and run servers in there without contemplating cost, heat/cooling, network allocation, and priviledge management (i.e. what services are running where, why, and who's managing it).

However, the smaller the organization, I can see this happening. 8 man startups without a system administrator... Now that is certainly reality.
