PANAJI: Cloud computing refers to the logical computational resources – data and software - accessible via a computer network, rather than from a local computer. That means no need of hard drives and other memory devices.
Users or clients can perform a task, such as word processing, with a client such as browser and with service provided through such cloud-based computational resources. Since the cloud is the underlying delivery mechanism, cloud-based remote applications and services may support any type of software application or service in use today.
In the past, tasks such as word processing were not possible without the installation of software on a local computer. With the development of Local Area Networks and wider bandwidth, multiple CPUs and storage devices could be used to host services like word processing in a remotely managed data center. Cloud computing takes away the installation and upgrades hassles and need for higher computing power from users and gives more control to the service providers on administration of the services.
Consumers now routinely use data-intensive applications driven by cloud technology that were previously unavailable due to cost and deployment complexity. In many companies, employees and company departments are bringing a flood of consumer technology into the workplace, which raises legal compliance and security concerns for the corporation.
The term “software as a service” is
sometimes used to describe programs offered through “The Cloud”.
How does it work?
Cloud computing utilizes the network as a means to connect the user to resources that are based in the cloud, as opposed to actually possessing them.
The cloud may be accessed via the Internet or a company network, or both. Cloud services may be designed to work equally well with Linux, Mac, and Windows platforms. With smartphones and tablets on the rise, cloud services have changed to allow access from any device connected to the Internet, allowing mobile workers access on-the-go, as in telecommuting, and extending the reach of business services provided by outsourcing.
Cloud in India
According to market research firm CyberMedia Research, the public cloud computing market in India is estimated to reach rupees 2,434 crore in 2014 after growing at a CAGR of 53 percent between 2010-2014.
