In its latest cloud computing market forecasts, Gartner has predicted that public cloud spending will climb 21.4 percent this year to reach $186.4 billion. Infrastructure as a service (IaaS) spending is growing faster than the market as a whole and will likely rise 35.9 percent in 2018 to hit $40.8 billion. However, the IaaS market is experiencing consolidation, and Gartner expects the top 10 vendors to control 70 percent of the market within four years.
Software as a service (SaaS) is the largest segment of the cloud computing market, and is growing at 22.2 percent annually.
