Forty three IT outsourcing firms sold more than $1bn worth of services as businesses spent $246bn worldwide, according to Gartner.

Fujitsu took over third place from CSC with sales growth of over 10% and revenue of just below $11bn. CSC dropped to fourth with flat sales of 10.3%.
Accenture was the biggest winner in the top 5 with 18% growth in revenues, which reached over $6.5bn. Other suppliers contributed 71.7% of revenues worth $176bn, which was 8.3% higher than last year.
India-based IT services providers show the highest growth levels. Wipro grew IT outsourcing revenue by 12.3%, Infosys by 17.9%, HCL by 26.0%, TCS by 29.8%, and Cognizant by 32.2% during 2011.
Bryan Britz, research director at Gartner said suppliers that focus on traditional infrastructure services could be hit hardest by the onset of cloud services. "Revenue cannibalisation resulting from client adoption of industrialised, and often cloud-based, services risks muting the growth opportunities for the ITO providers that are heavily weighted in infrastructure outsourcing.”
He said businesses will mix and match their IT outsourcing. "Strategies will vary as clients are likely to pursue hybrid cloud strategies requiring providers to deliver some asset-light and some asset-heavy offerings — which will result in varying growth trajectories among competitors over the next several years."
