Tier Classification System

ComputerSite Engineering is exclusively licensed to rate and Certify against the Uptime Institute's Tier Classification System. Many of ComputerSite Engineering's Principal-level consultants also serve as Institute faculty and are co-authors of the white paper, Tier Classifications Define Site Infrastructure Performance, the de facto industry standard for predicting site reliability.

The current list of clients with official Tier ratings includes industry-leading organizations around the world.


The authors of the Institute's Tiers white paper explain the practical application of Tier methodology in this Technical Users Guide, available only from ComputerSite Engineering


"Operational Sustainability" is the ability of a site to meet operational objectives over extended periods of time. A white paper on the subject was published by ComputerSite Engineering in March 2008 and can be found on our white papers page. Here is a brief definition of this new concept.
