Estimation of Global Public IaaS market concentration by Linda index

Infrastructure as a Service (IaaS) is one of three key cloud market segments, that include also Platform as a Service (PaaS) and Software as a Service (SaaS). Representing less than a third of the entire market, this segment is projected to keep the higher pace of growth over the next few years. But this growth is mainly driven by market leaders - technology companies with a diversified international business, thereby increasing the concentration of the largest players in the market. This article defines the degree of global IaaS market concentration and whether an oligopoly is being formed. The Linda index is utilized for determination of “oligopoly boundary”- number of key market players.
