On the institute Gartner study estimates that global spending in the field of information technology (IT) could represent 3.4 trillion (10 ^ 12) $ in 2008. An increase of 8% compared to 2007, which analysts attributed in part to the fall of the dollar, but also in emerging countries, renewal of infrastructure and development solutions "on demand". In currency growth of IT spending amounts to 4.5%."The projects computing" on demand "(Editor's Note: Rentals of computing power or infrastructure) will lead by example, by a dramatic growth of IT spending in some areas and significant reductions in others said Jim Tully, vice president of Gartner. In general, the assets will be used with greater efficiency, and we assume that the overall effect on market growth will be neutral. But we also recognize that there is considerable potential for growth. " The software costs to end-users for their part are going to exceed 196 billion in 2008 (+10%), and expenditure on equipment (hardware) would reach nearly 408 billion dollars (+7%). As for servers, the worldwide turnover in this market have increased by 5.7% to $ 13.8 billion, or approximately two million servers shipped. "Most companies have updated their software systems between 1997 and 2001. We are therefore in the midst of a cycle of upgrades which should be extended until the end of the decade, said Joanne Correia, vice-chairwoman of the management section at Gartner. The computer and software on demand (SaaS), service-oriented architecture (SOA) and Web 2.0, as well as open source software have led to huge changes in the software market, she said. Many of these factors have an impact on its growth as companies gradually replacing their assets by on-demand services. " In the field of software customer relationship management (CRM), Gartner provides yet a sharp rise in income compared to 2007 (14.2%), or 7.8 billion dollars this year. The Institute expects a continuous progression of this market until 2012, when he is expected to reach 13.3 billion dollars of income earned. "Historically, the market for CRM is subject to economic fluctuations," said Sharon Mertz, research director at Gartner. It is difficult to predict the outcome of the fiasco of subprimes, but so far, companies spend more. We are still vigilant. " Regarding telecommunications, global spending could reach almost $ 1.2 trillion (10 ^ 12), representing an increase of 8% compared to 2007, and IT services approximately 819 billion dollars. The two sectors together account for two billion dollars (10 ^ 12), or 70% of total IT spending worldwide.
