According to the global research firm Gartner, the global public cloud services market is expected to increase from $111 billion in 2012 to $131 billion worldwide in 2013.

Also, infrastructure-as-a-service (IaaS) including cloud computing, storage, and print services, continues to be the fastest-growing segment of the market. It is expected to increase from $6.1 billion in 2012 to $9 billion in 2013. Further, cloud advertising continues to be the largest segment of the cloud services market, comprising 48 per cent of the total market in 2012. Gartner predicts that from 2013 through 2016, nearly $677 billion will be spent on cloud services worldwide. Out of which, $310 billion will be spent on cloud advertising.

Ed Anderson, research director, Gartner, says, ?The continued growth of the cloud services market will result from the adoption of cloud services for production systems and workloads, in addition to the development and testing scenarios that have led as the most prominent use case for public cloud services to date.?

He adds, ?Evidence of this growth is found in the increasing demand for cloud services from end-user organisations, met by an increased supply of cloud services from suppliers.?

According to Gartner, the cloud business process services segment (BPaaS) is the second-largest market segment following cloud advertising. In 2012, BPaaS accounted for 28 per cent of the total cloud market in 2012, followed by cloud application services (software-as- a-service) with a 14.7 market share.

In 2012, IaaS, cloud management and security services and cloud application infrastructure services had a market share of 5.5 per cent, cloud management and security services at 2.8 per cent, and cloud application infrastructure services (platform as a service) had 1 per cent market share.

According to Gartner, the emerging markets in Asia/Pacific, Latin America, Eastern Europe, the Middle East and North Africa show the highest growth rates in cloud services market, while representing the smallest overall markets. China is the exception, being both a large and growing market. Also, the mature markets of North America, Western Europe, Japan and the mature Asia/Pacific countries constitute the larger market for cloud-based services, however, they witness slower growth rates.
