In simple words, Cloud Computing means delivery of computing services or business software/ applications via internet
. Typically Cloud Computing comprises of five imperative characteristics, which are as follows: -
On-demand scalability
Broad network accessibility
Resource pooling

Usage-based billing (i.e., pay as you go)
Cloud computing can be explained under three primary service models:
Infrastructure as a Service (IaaS)
-It includes raw computing power, data storage and network bandwidth.
Platform as a Service (PaaS)
-It includes database, development tools and other modules essential to support the delivery of applications
Software as a Service (SaaS)
- It includes software both general as well specialized. When we talk about general applications they include email, spreadsheet, word processing, etc. When we talk about specialized applications then I must mention as customer relationship management (CRM), enterprise resource management (ERM), Accounting software, Tax applications, etc.
Over time, style of doing business has changed a lot. Some business enterprises are employing SAAS, some PAAS and others IAAS. According to a survey 80 percent of business enterprises are utilizing cloud computing service in one or the other way. SAAS is most popular and preferred way of employing cloud services. In simplified words it is also known as Application Hosting. Application hosting when done via cloud computing technology becomes Cloud hosting.

Sometimes, the hosting vendor and the software provider are same. Usually the customer have contract with the cloud vendors, Cloud hosting service providers offer number of features and facilities to the users.

They can easily adept according to market demands. This is a cost-effective way to use business as well as general applications.
