How cloud computing will affect businesses - Research Paper Example Cloud Computing is a term that has gained popularity within last couple of years. Figure 1 shows the trends in the usage various computing terms, the figure is indicative of the fact that the terms like grid computing and distributed computing are dropping in usage where as from 2008 onwards the term cloud computing has picked up at an exponential rate. Cloud computing has been defined as â€Å"†¦.a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS)†¦.† (Search Cloud Computing). The term Cloud is a metaphor of Internet as Internet it is represented as a cloud in schematics and diagrams Figure 1. Trends of usage of term Cloud Computing. Cloud computing has numerous benefits and these beneficiaries not only include the users but also the companies. Cloud computing is beginning to change the way businesses are done. The following are the key benefits of cloud computing: Cloud Computing enables the users to access information (files and data) remotely, that is from their home or office, during working hours or even beyond working hours. Cloud computing is relatively cheaper with respect to the resources, for smaller companies and companies in resource limited settings cloud computing provides low cost solutions because these users need not procure expensive software and hardware. The companies just need to pay for the services and infrastructure when it is required, thereby reducing the costs. Since cloud computing is all about online or virtual resources, resources like storage space etc. for the companies into cloud-based services is limitless. Monthly subscription fee takes care of the growing needs of the companies . In other words, cloud computing offers such advantages capable of posting the companies, those adopt cloud computing, in all together a different league because the scales and economics are a class apart.

These include concerns like the additional costs for transfer of data; lack of control over security, reliability of the hardware where the data and applications reside, because the hardware and software etc. are owned by third party; since cloud computing is a service oriented technology, quality of service of each vendor can vary, hence this technology can not be considered to be free from qualitative aspects like, security issues, etc. Figure 2 gives an idea of the pros and cons of
