The worldwide public cloud services market is projected to grow 17.5 percent in 2019 to total USD 214.3 billion, up from USD 182.4 billion in 2018. The fastest-growing market segment will be cloud system infrastructure services, or infrastructure as a service (IaaS), which is forecast to grow 27.5 percent in 2019 to reach USD 38.9 billion, up from USD 30.5 billion in 2018. The second-highest growth rate of 21.8 percent will be achieved by cloud application infrastructure services, or platform as a service (PaaS). More than a third of organizations see cloud investments as a top three investing priority, which is impacting market offerings. By the end of 2019, more than 30 percent of technology providers’ new software investments will shift from cloud-first to cloud-only. This means that license-based software consumption will further plummet, while SaaS and subscription-based cloud consumption models continue their rise.
