Cloud computing is the use of hardware and software housed within a data facility and delivered over an Internet-driven network. With cloud computing, customers don’t have to personally manage their data, software, and computation because these services are housed in a secure facility. Hardware, servers, connections, air-conditioning, and power are provided in a cost-effective manner to prevent loss of data and business functionality due to local disaster or or other interruptions of support services. Cloud providers manage the infrastructure and platforms on which the applications run.
Leasing needed business applications in the cloud can be much more cost-effective than purchasing the software outright and paying for licenses, renewals, and upgrades. The business model, IT as a service (ITaaS), allows the company’s internal IT department to focus on creative ways to enhance the business instead of dealing with time-consuming challenges and emergency IT requirements.

How Does It Work?
Like other utility providers (electricity, water, gas), cloud computing shares resources over multiple servers to improve availability over broadband accesses. End users can access cloud-based applications through a web browser on a desktop, laptop, tablet, or mobile phone, while the business software and user’s data are stored on servers at a remote location. Cloud computing allows businesses to reduce application set-up intervals, reduce maintenance time and resources, and enables the organization to leverage third party IT services and/ or allows existing IT departments to focus on improving business operations and time for more creative IT solutions.
