Abstract
Cloud computing technology has been a new buzzword in the IT industry and expecting a new horizon for coming world. It is a style of computing which is having dynamically scalable virtualized resources provided as a service over the Internet. It reduces the time required to procure heavy resources and boot new server instances in minutes, allowing one to quickly scale capacity, both up and down, as ones requirement changes. Nevertheless the technology is hot in the market and is ready to cater to the small and medium business segment. As per one of the estimates from Gartner, by year 2012, 20% of enterprise market e-mail seats will be delivered via Cloud. As per another estimate from Gartner, Software as a Service is forecast to have a compound annual growth rate of 17% through 2011 for CRM, ERP and SCM markets in SMB segment. While the enterprises are exploring the possibilities of adopting this technology, it is imperative for these enterprises to critically evaluate the feasibility of this technology for their specific businesses.
The typical characteristic of this technology:
Cloud computing customers do not generally own the physical infrastructure serving as host to the software platform in question. Instead, they avoid capital expenditure by renting usage from a third-party provider. The entire onus lies on the service provider who owns the huge scalable and variable host of infrastructure, software and bundle of other services. Cloud computing consumers consume resources as a service and pay only for resources that they use. Many cloud-computing offerings employ the utility computing model, which is analogous to how traditional utility services (such as electricity) are consumed, while others bill on a subscription basis. Sharing "perishable and intangible" computing power among multiple tenants can improve utilization rates, as servers are not unnecessarily left idle (which can reduce costs significantly while increasing the speed of application development).
This article provides brief details about the cloud computing with an overview of key features to give a glimpse about the new focused technology.
Look up on few facts:
What is Cloud Computing?
Cloud computing is emerging at the convergence of three major trends — service orientation, virtualization and standardization of computing through the Internet. Cloud computing enables users and developers to utilize services without knowledge of, expertise with, nor control over the technology infrastructure that supports them. The concept generally incorporates combinations of the following:
Infrastructure as a service (IaaS) Platform as a service (PaaS) Software as a service (SaaS)
Users avoid capital expenditure (CapEx) on hardware, software, and services when they pay a provider only for what they use. Consumption is billed on a utility (e.g. resources consumed, like electricity) or subscription (e.g. time based, like a newspaper) basis with little or no upfront cost.
Cloud Vendors
There are many companies who are into the market offering various ranges of services on Cloud Computing. The major players are Vmware, Sun Microsystems, Rackspace US, IBM, Amazon, Google, Microsoft, and Yahoo. Cloud services are also being adopted by individual users through large enterprises including Vmware, General Electric, and Procter & Gamble. The vendor hosts and manages the infrastructure required with the respective technology.
Cloud as a Service to Customer
The cloud computing that are evolving as a service in the cloud are being provided by big enterprises with a heavy investment with resource and technology which are accessed by others via the internet. The resources are accessed in this manner as a service – often on a subscription basis. The users of the services being offered often have very little knowledge of the technology being used. The users also have no control over the infrastructure that supports the technology they are using.
There are six different forms that have been consolidated so far to understand how the services are being provided to the customers:
