Make sure you leverage the price/performance advantages of software/hardware integrationand systems that have been optimized for the particularneeds of your workloads.Automate: Leverage every opportunity to take advantageof self tuning and automation capabilities provided bysystems. Eliminating manual repetitive tasks will cut downsystems management and administration costs whilemeeting service level agreements.Secure: The economic impact of a security breach couldbe devastating. Make sure your computing foundation isrock solid in terms of security, privacy and compliancerequirements. Ensure your data is secure in all phases ofuse—whether at rest or in motion.Judicious use of these principles of Smarter Computingwill help clients transform their IT service delivery and drivedown costs.
