Dans le langage courant, l'acronyme DCIM est utilisé principalement pour désigner le système informatique de supervision de ces infrastructures. Around the time of the dot-com bubble in the late nineties, the need for internet speed and a constant internet presence for companies necessitated larger facilities to house the amount of networking equipment needed. Indispensable à Internet, il a connu un fort développement avec l’essor du cloud computing. In addition to the energy savings, reduction in staffing costs and the ability to locate the site further from population centers, implementing a lights-out data center reduces the threat of malicious attacks upon the infrastructure.. Software including data center infrastructure management tools allow remote IT administrators to oversee the facility and equipment, measure performance, detect failures and implement a wide array of corrective actions without ever physically entering the data center room. Some of the servers at the data center are used for running the basic Internet and intranet services needed by internal users in the organization, e.g., e-mail servers, proxy servers, and DNS servers.  Furthermore, overcooling equipment in environments with a high relative humidity can expose equipment to a high amount of moisture that facilitates the growth of salt deposits on conductive filaments in the circuitry..
