Cloud Computing and the Economics of Enterprise IT
Enterprise IT departments need to respond with agility to business needs and demand fluctuations, which existing data center architectures cannot achieve. Private cloud computing - highly scalable IT resources abstracted from an underlying infrastructure and provided as needed in a multi-tenant environment - has emerged as a prime vehicle for creating agile IT environments. Private cloud computing is not a solution for every organization, but close examination reveals that many businesses and even some industries are well placed to achieve its benefits: those spending a high proportion of their technology budgets on infrastructure and running applications on x86 platforms. Other leading indicators that affect the attractiveness of private cloud computing for a given business include workload predictability, security constraints, and licensing requirements.
