Gartner forecasts: Infrastructure services will accelerate cloud computing growth

As public cloud computing is becoming more widely used in the enterprise, higher-level IT spending is being staged in infrastructure-related services, including infrastructure as a service IaaS. As public cloud computing is becoming more widely used in the enterprise, higher-level IT spending is being staged in infrastructure-related services, including infrastructure as a service IaaS.

The first thing companies consider is how to integrate cloud systems and legacy systems together to make the most of the data accumulated in the past. From the legacy ERP system to the CRM system, the integration of legacy systems and cloud-based platforms will accelerate to 2016 years. This trend has been found in conversations between distributors and corporate customers, and Gartner's latest report on the public cloud has also reflected the trend, the report's name is "forecast Overview: Global 2011-2016 Public cloud Services," released last February 8. Here are some of the key elements of the report:

Global public cloud services are expected to grow by 18.6% in 2012, at $110.3 billion a year, from 2011 to 2016, with a composite annual growth rate of 17.7%. The total market is expected to grow from $76.9 billion trillion in 2010 to $210 billion in 2016. The following is an analysis of the market size and annual growth rate of public cloud services:

Gartner predicts that infrastructure as a service (IaaS) will achieve a composite annual growth rate of 41.3% per cent by 2016, the fastest growing area in public cloud computing (CAGR). The following figure is the relative market size for each segment of the public cloud service market:

Platform as a service (PaaS) will achieve a 27.7% annual composite growth rate by 2016, with cloud management and security services reaching 26.7%. The composite annual growth rate of software SaaS is expected to be 19.5% by 2016. The following figure shows the different composite annual growth rates for the 2011-2016 forecast period:
