Cloud Computing

Cloud Computing


Cloud computing is Internet-based computing, whereby shared servers provide
resources, software, and data to computers and other devices on demand, as
with the electricity grid. Cloud computing is a natural evolution of the widespread
adoption of virtualization, service-oriented architecture and utility computing.
Details are abstracted from consumers, who no longer have need for expertise
in, or control over, the technology infrastructure "in the cloud" that supports them.


The fundamental concept of cloud computing is that the computing is "in the cloud" i.e. that the processing (and the related data) is not in a specified, known or static place(s).

Cloud computing users avoid capital expenditure (CapEx) on hardware, software, and services when they pay a provider only for what they use. Consumption is usually billed on a utility (resources consumed, like electricity) or subscription (time-based, like a newspaper) basis with little or no upfront cost. Other benefits of this approach are low barriers to entry, shared infrastructure and costs, low management overhead, and immediate access to a broad range of applications. In general, users can terminate the contract at any time (thereby avoiding return on investment risk and uncertainty), and the services are often covered by service level agreements (SLAs) with financial penalties.
