What is Cloud Computing?

Cloud computing is a new computing technology refers to the on-demand provision of computational resources   via a computer network, rather than from a local computer. Users or clients can submit a task to the service provider, without actually possessing the software or hardware. The consumer's computer may contain very little software or data (a minimal operating system and web browser only), serving as a basic display terminal connected to the Internet. Since the cloud is the underlying delivery mechanism, cloud-based applications and services may support any type of software application or service in use today.  Cloud computing service in short is called "The Cloud".  Previously both data and software had to be stored and processed on  the computer. The development of Local Area Networks allowed for a system could be organized to increase the performance of the entire system. In an extension to that concept, cloud computing fundamentally allows for a functional separation between the resources used and the user's computer, usually residing outside the local network  Consumers now routinely use data-intensive applications driven by cloud technology that were previously unavailable due to cost and deployment complexity.  In  cloud computing,  any computer connected to the Internet is connected to the same pool of computing power, applications, and files. Users can store and access personal files such as music, pictures, videos, and bookmarks or play games  on a remote server  rather than physically carrying around a storage medium such as a, pen drive or  DVD   Even those using web-based email  such as Gmail, , Yahoo! or  Outlook  are making use of cloud email servers. Hence, desktop applications that connect to internet-host email providers can also be considered cloud applications. The National Institute of Standards and Technology (NIST )provides a concise and specific definition: “ Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. “. Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and diagrams. A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour; it is elastic -- a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access). Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a weak economy, have accelerated interest in cloud computing. A cloud can be private or public. A public cloud sells services to anyone on the Internet. (Currently, Amazon Web Services is the largest public cloud provider.) A private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people. When a service provider uses public cloud resources to create their private cloud, the result...
