After years of data center growth and IT evolution, many businesses are left living with complex, overgrown computing platforms that are chronically underutilized. These systems take up valuable data center floor space, depreciate quickly, consume large amounts of power and cooling resources, and can cause management headaches. Plus, this rigid architecture makes it hard for an IT organization to quickly adapt or respond to changing business demands, and it makes it difficult to share resources throughout an enterprise, in order to increase utilization and improve efficiency.
By providing resources as a service, cloud computing addresses these fundamental data center challenges. Some examples of applications include software as a service (SaaS), Customer Relationship Management, file storage, file synchronization and file back-up. It's now possible for businesses to have their own private cloud, which incorporates specific services and is only accessible to specific people.
