Many IT organizations are struggling to cope with the ever-growing complexity of the IT infrastructure in today’s data centers. To compound this challenge, they must also balance the need to respond to pressure for delivering IT services faster and more cost effectively than ever before. As a result of these economic and staffing pressures, many organizations are seeking alternate service delivery and enterprise management approaches. These approaches can balance the need for control while reducing risk and increasing agility in providing cost-effective service delivery.
Cloud computing is a model for convenient, on-demand network access to a shared pool of configurable computing resources. Dynamically scalable resources are provisioned as a service over the Internet, with minimal management effort or service provider interaction. Cloud computing offers greater business agility, tighter cost control, and higher service availability.
