BENEFITS OF CLOUD COMPUTING


Introduction to Cloud Computing:
Cloud computing can be referred as a new computing style in which dynamically scalable and always virtualized resources are offered as a service over internet. Cloud computing has become an essential trend of technology and several professionals expect that cloud computing will reshape information technology marketplace and information technology processes.
Benefits of Cloud Computing:
According to Armburst et al (2010) the most essential benefit of cloud computing is that firms can reduce their expenditures of capital and use operational expenditures for developing their capabilities of computing. This is a lower obstacle to entry and also needs fewer in house information technology resources to offer system assistance. Another benefit of cloud computing is that firms can initiate with a little deployment and develop at a big deployment rapidly and scale back if essential. Buyya et al (2009) has mentioned that the cloud computing flexibility permits firms to use additional resources at peak times enhancing them to fulfill the demands of customers. Maintenance, is also one of the benefits of cloud computing. The providers of cloud service perform the maintenance of system and access through application programming interfaces that do not need installations of applications onto personal computers. With the technology of cloud computing users use different devices involving laptops, personal computers, personal digital assistants and smart phones to access programs, application development and storage platforms over internet through services provided by the providers of cloud computing. Mather, Kumaraswamy and Latif (2009) have described that the features of cloud computing involves wide access of network, on demand self service, rapid elasticity, measured service and resource pooling. Another benefit is reliability where the services using numerous redundant sites can assist disaster recovery and continuity of business. The last benefit of cloud computing is mobile accessibility where mobile employees have developed productivity because of system accessible in an infrastructure feasible from anywhere.
Conclusion:
Cloud computing develops profitability by developing utilization of resources. Costs are reduced by providing proper resources only for the time those resources are required. Cloud computing is altering the way information technology departments purchase information technology. Businesses have an extent of paths to the cloud involving platforms, infrastructure and applications that are accessible from providers of cloud as online services.
