Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user.

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 actual term “Cloud” borrows from telephony in that telecommunications companies, who until the 1990s offered primarily dedicated point-to-point data circuits, began offering Virtual Private Network services with the lower price and quality of service.

Benefits of Cloud Computing?

Emergence of Cloud computing provides a lot of benefits that you would not expect to find in a conventional enterprise setting.

• Reduce costs for storage services or cloud services.
• An individual can only be charged for the resources they used.
• Centralization and specialisation of data.
• Improve the reliability of the data.
• Lowering security expenses.

Characteristics of Cloud Computing

These services mature both commercially and technologically because it will be easier for companies to maximize the potential benefits. There are some of the characteristics.

• Cloud Computing is Virtual
• Can be secure & affordable.
• Flexible and scalable.
• Multi-tenancy and resource pooling.
• Broad network access.
• On-demand self-service.
• Measured service.

So simply cloud computing means a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (network, servers, storage, application, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
