Cloud computing is a flexible, cost-effective and proven delivery platform for providing business or consumer IT services over the Internet. Cloud resources can be rapidly deployed and easily scaled, with all processes, applications and services provisioned "on demand," regardless of user location or device.

As a result, cloud computing gives organizations the opportunity to increase their service delivery efficiencies, streamline IT management and better align IT services with dynamic business requirements. In many ways, cloud computing offers the "best of both worlds," providing solid support for core business functions along with the capacity to develop new and innovative services.

Both public and private cloud models are now in use. Available to anyone with Internet access, public models include Software as a Service (SaaS) clouds like IBM LotusLive, Platform as a Service (PaaS) clouds such as IBM Computing on Demand, and Security and Data Protection as a Service (SDPaaS) clouds like the IBM Vulnerability Management Service.

Private clouds are owned and used by a single organization. They offer many of the same benefits as public clouds, and they give the owner organization greater flexibility and control. Furthermore, private clouds can provide lower latency than public clouds during peak traffic periods. Many organizations embrace both public and private cloud computing by integrating the two models into hybrid clouds. These hybrids are designed to meet specific business and technology requirements, helping to optimize security and privacy with a minimum investment in fixed IT costs.
