Amazon, Microsoft, and IBM were found to account for well over half of IaaS revenue in 2013.
A new study from IHS found the Infrastructure as a Service (IaaS) market to be worth just over $4 billion in 2013. IaaS is a service that allows for on-demand use of servers, networks, storage, and operating systems. It is just one of the three categories of cloud computing, the others being Platform as a Service (PaaS) and Software as a Service (Saas). The latter of which accounts for the largest share of cloud revenues.
Amazon, Microsoft, and IBM were found to account for well over half of IaaS revenue in 2013. Google was absent from market share estimates in 2013, given that it only introduced its offering in December of that year. However, because of the company’s scale, existing data center infrastructure, and resources available for investment, IHS expects the company to be in the top five suppliers to the market for 2014. Other major suppliers that the report analyzes (both in terms of revenues and data center footprint) are AT&T, British Telecom, CenturyLink, Hewlett-Packard, Internap, Rackspace, Verizon Terremark, and VMware.
