IT service providers get the big picture.
While pure-play cloud providers obviously can meet cloud-specific requirements, IT service providers often have extensive experience designing and supporting enterprises' broader IT architectures, which is also essential for successful cloud deployments. For example, a cloud implementation can often involve a multi-year journey that requires intense support at various stages, from determining the level of cloud readiness at the beginning to becoming fully cloud-ready.
The process also often involves planning and integration work in the areas of networking, application rationalization, governance, security and more. IT service providers often have the expertise and capabilities to be a one-stop shop that can address all of these needs during a cloud deployment. - See more at: http://www.eweek.com/cloud/it-service-providers-want-cloud-users-to-think-global-act-local-in-2013#sthash.paN8hcUM.dpuf
