, categorizes a series of high growth markets (Redshifting) while predicting slower GDP-driven growth in traditional computing markets (Blueshifting). Papadopoulos predicts the result will be a fundamental redesign of components comprising computing systems.

Hypergrowth market segments (Redshifting)

According to the Redshift theory, applications "redshift" when they grow dramatically faster than Moore's Law allows, growing quickly in their absolute number of systems. In these markets, customers are running out of datacenter real-estate, power and cooling infrastructure. According to Dell

High Performance Computing (HPC) 

These are companies that do complex simulations that involve (for example) weather, stock markets or drug-design simulations. This is a generally elastic market because businesses frequently spend every "available" dollar budgeted for IT. A common anecdote claims that cutting the cost of computing by half causes customers in this segment to buy at least twice as much, because each marginal IT dollar spent contributes to business advantage.

*prise (or "Star-prise")

Traditional Computing Markets (Blueshifting)

Redshift theory suggests that traditional computing markets, such as those serving Enterprise Resource Planning (ERP)

 growth, which typically remains under 10% for most countries annually. Given that Moore's Law continues to predict accurately the rate of computing transistor growth, which roughly translates into computing power doubling every two years, the Redshift theory suggests that traditional computing markets will ultimately contract as a percentage of computing expenditures over time.

Functionally, this means “Blueshifting” customers can satisfy computing requirement growth by swapping in faster processors without increasing the absolute number of computing systems.

Consequences & Industry Commentary

Papadopoulos argues that while traditional computing markets remain the dominant source of revenue through the late 2000s, a shift to hypergrowth markets will inevitably occur. When that shift occurs, he argues computing (but not computers) will become a utility, and differentiation in
the IT market will be based upon a company's ability to deliver computing at massive scale, efficiently and with predictable service levels, much like electricity today.

If computing is to be delivered as a utility, Nicholas

refers to what happens when electromagnetic radiation, usually visible light, moves away from an observer. Papadopoulos chose this term to reflect growth markets because redshift helped cosmologists explain the expansion of the universe.

Papadopoulos originally depicted traditional IT markets as green to represent their revenue base, but later changed them to “blueshift,” which occurs when a light source moves toward an observer, similar to what would happen during a contraction of the universe.
