Over the years, the business and computing environments have benefited from a large number of technological innovation. In the recent years, however, technology has leaped over to provide business enterprises with an innovative platform that has the potential to transform the way IT services are delivered and managed. Considering the ever changing customer demands and the responding market changes in a globalized business environment, the IT giants today offer the techno savvy enterprises utility computing with cloud computing services. The Cloud computing services is a convenient and on-demand model for network access that provides enterprises with significant cost savings, reduced complexity, and increased flexibility in managing IT infrastructure and challenging market demands. Though based on a new approach, this works on the same concepts and practices, as used earlier. Cloud computing services gives a new perspective to the way enterprises develop, deploy, update and maintain the applications and infrastructure used. In era when enterprises have their business spread across the length and breadth of the globe with a large percentage of workforce either working at offshore locations as distributed teams or as part of the mobile workforce, thecloud computing providers facilitates them with anytime anywhere access to the corporate network and business critical data. Further this provides them with mobility and higher reliability when faced with business continuity issues. Gartner defines cloud computing as “a style of computing where massively scalable IT-related capabilities are provided 'as a service' across the Internet to multiple external customers”. Irrespective of the type of service model through which these applications are made available either software-as-a-service, Infrastructure-as-a-service or Platform-as-a-service, cloud computing is identified by five essential characteristics such as • Enhanced flexibility • Measured service • On-demand self service • Wide network access • Resource Pooling However, these services are deployed at the global enterprise networks and data centers as private cloud, Public cloud, Hybrid cloud and community cloud. Besides these established trends, the cloud computing service providers also offer a pay-as-you-use model or utility computing model that supports the capacity and performance of service-level with virtualization as the key feature. Utility computing model benefits enterprise both through short-term and long-term benefits. The short-term benefits include : • Leveraging on next generation technologies • aligning IT infrastructure costs with revenue stream and business growth • tailored solutions delivered through end-to-end architecture The long-term benefits of cloud computing service include efficiency and cost-control, better business, low cost of entry and stronger IT focus. Most of thedata centersmake use of the utility computing model as they can allow their client enterprises self-provision servers, network, storage infrastructure and access to resources over a secure connection in real-time from anywhere and anytime. Such virtual environments reduces the need for network penetration testing and firewalls and provides a single point of control to manage multiple layers of complex infrastructure.
