The Open Groups long awaited guidance on Cloud is now published!
Cloud Computing is the major evolution today in computing. It describes how the internet has enabled organizations to access computing resources as a commodity and when needed in much the same way as households access household utilities.
For Enterprises with complex and expensive IT systems, the idea of paying on demand for someone else to provide IT services is attractive. This authoritative guide is specifically designed for business managers to understand the benefits that can be achieved; including
Improved timeliness and agility
Resource optimisation
Control and reduction of costs
More innovation
Increased security
Decreased exposure to risk
Demonstration of compliance
Improved quality of support
Improved business continuity resource
The authoritative title, published by the globally respected Open Group, gives Managers reliable and independent guidance that will help to support decisions and actions in this key operational area.
