Flat or shrinking IT budgets even as business expectations increase. “Keeping the lights on” mandate reduces agility to address app owners’ needs. Efficient datacenter operations across entire customer base. Need to offer differentiated services to customers. Enterpriseclass Simple and cost-effective Complexities due to diverse datacenter infrastructure. End user pressure to enable access to corporate information from a variety of devices.
