Cloud computing, often referred to as simply ‘the cloud’ is the delivery of on-demand computing resources everything from applications to data centres over the internet on a pay-for-use basis.
Cloud computing is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.
The salient characteristics of cloud computing based on the definitions provided by the National Institute of Standards and Terminology (NIST) are outlined below.
3.2 Characteristic of Cloud Computing

This eventually reduces the cost of computing. Pricing is based on the utility according to the usage. One need not be IT professional to implement the infrastructure. The e-FISCAL project's database contains several articles which have details about cost aspect and most of them conclude that cost savings depends on the IT support and type of IT infrastructure available in- house.
• Device and location independence- Cloud computing enable users to access systems using a web browser from any of their locations. It also enables to use multiple devices like computer, tab or mobile phones. Users can connect from anywhere as infrastructure is off-site (typically provided by a third-party) and accessed via the internet.
• Easy Maintenance- In a cloud computing the application need not be installed on each user’s computer. The application can be accessed from anywhere in the world and so maintenance of the cloud computing is easier and time saving.
• Multiple Users- Cloud computing enables sharing of resources and cost across a large number of users, thus allowing
