It easily handles peak load situations without the need for additional hardware infrastructures that would remain largely underutilized. Resources can be virtualized and presented to customers as virtual servers which they manage themselves. Storing data in the cloud has some distinct advantages over client- based access. It is possible to use the processing power of the cloud to do things that traditional productivity applications cannot do. For Example, users can instantly search over GBs of online, which is practically impossible to do on a desktop.

One of the greatest advantages is that the user is no longer tied to a traditional computer to use an application, or has to buy a version specifically configured for a phone, PDA or other device. In future any device that can access the Internet will be able to run a cloud-based application. Users will not have to worry about storage capacity, compatibility or other matters. Also, when accessing an application on the cloud, the user can be sure of getting the latest version (without having to upgrade the version stored hard drive).

Cloud Computing infrastructure allows the enterprises to use the resources more efficiently so as to maximize the ROI (Return on Investment). Cloud Computing enables Innovation. The architecture allows enterprises in pooling resources into large clouds to cut down costs and increase utilization. Cloud Computing architecture provides improved automation services, improved flexibility, and sustainability. It can be located in areas with lower costs of space and electricity. Cloud computing provides quickness in terms of procurement and acquisition process and timelines.

Cloud Computing has an ability to scale on demand(It scales resources up and down when needed which allows for speedy growth). Cloud Computing helps in improving productivity of the Small and Medium level companies efficiently by reducing the amount of money spent for resources and equipments. It also helps the large firms to improve cost savings, ease of availability, remote access and real-time collaboration capabilities. Sharing resources is another key component from company’s perspective.
