Cloud computing market development will rely on infrastructure services

Public cloud computing has become more widespread in the enterprise, and higher-level IT spending is also being inflated with infrastructure-related services, including infrastructure as a service, IaaS.

The first thing businesses consider is how to bring together cloud systems and legacy systems to take full advantage of the data that was accumulated in the past. From legacy ERP systems to CRM systems, the integration of legacy systems with cloud-based platforms will accelerate to 2016. This trend is already evident in the dialogue between resellers and corporate customers, as is also reflected in Gartner's latest report on public cloud adoption, entitled "Forecasting Overview: Global 2011-2016 Public Cloud Services," Posted on February 8 recently. Here are some key elements in this report:

Global public cloud service spending is expected to grow 18.6% in 2012 to 110.3 billion US dollars, from 2011 to 2016 CAGR of 17.7%. The total market is expected to grow from $ 76.9 billion in 2010 to $ 210 billion in 2016. The following is the public cloud services market size and annual growth rate analysis:

Gartner predicts that infrastructure as a service (IaaS) will reach CAGR of 41.3% by 2016, the fastest growing area in public cloud computing. The figure below shows the relative market size of each segment of the public cloud service market:

PaaS will reach 27.7% CAGR by 2016 and 26.7% for cloud management and security services. The CAGR of SaaS Software is projected to reach 19.5% by 2016. The chart below shows the different CAGRs for the 2011-2016 forecast period:

Gartner predicts that the CAGR of the SaaS market will stabilize at 19.5% during 2011-2016, a 0.4% increase over the previous forecast. Global SaaS spending is projected to increase from $ 13.5 billion in 2011 to $ 32.8 billion in 2016.

CRM will continue to be the largest market in the world for SaaS and is expected to increase from $ 5 billion in 2012 to $ 9 billion in 2016 with a CAGR of 16.3%. The SaaS market is still the fastest growing office suite (49.1%), followed by digital content creation (34.0%). The graph below shows the compound annual growth rate for all the public cloud service categories over the forecast period:

59% of all new cloud computing services come from North American companies, and the trend is expected to accelerate by 2016. Western Europe is expected to account for 24% of all spending. A comparison of the geography and the corresponding total growth rate of expenditure is as follows:

The following table provides a summary of the expense projections for each category of public cloud computing over the forecast period.
