Aljabre, A., 2012. Cloud computing for increased business value. International Journal of Business and Social Science, 3(1).
According Aljabre (2012), today Cloud Cmputing has become the key to success for all growing business. It provides disruptive innovation to the growing business which ensures its productivity and profitability. Amazon cloud service being a very popular provider for this innovation in business. It serves as a great advantage by providing the business their software needs in fragments earlier for which company required to pay huge amounts. In addition the user does not require having those applications on their Desktops or PCs which makes their devices faster along with serving with a very low cost.
Aljabre (2012) thinks it to be an effective way of reducing the extra cost of software that every computer at the business premises requires. Along with higher storage capacity it serves to be more compatible with the operating system. Multiple user collaboration is another feature highlighted by the author. Aljabre (2012) with the advantages points out the disadvantages too under which constant internet connection is the most important one. Secondly it is considered very much unsafe by the users which in business perspective can be a huge drawback. Unauthorized people can access data by hacking into the cloud. The user ability and its popularity is making it more and more important for every business except for small ones.
Grossman, R.L., 2009. The case for cloud computing. IT professional, 11(2), pp.23-27.
Grossman (2009), describes cloud as a network of several distributed computers which enhances business’ profit level by providing them with extra advantage leveraging the competition too. The companies earlier required to buy huge numbers of Hardware and software so as to deal with their daily need but now they can easily cut down that extra cost of infrastructure through cloud computing. It provides great business continuity by performing huge number of operations at one go. Managing huge racks of data through traditional methods has been addressed as very difficult by the author.
Interoperability serves as a great advantage by helping user to switch between applications much faster and in a more efficient way at a very low cost. Although author considers security being the biggest challenge which needs to be addressed Hadoop being the most appropriate example not providing access controls. Also standards of cloud computing is another issue with no provision for a common language. The cloud comes with several possibilities of storing or computation. This means that the cloud can acts a data cloud, compute cloud as well as storage cloud. Huge companies prefer using a Layered model providing al at one place. Howsoever the author accepts cloud computing as virtual technologies reducing the complexity and easing the way data is accessed today in business.
Motahari-Nezhad, H.R., Stephenson, B. and Singhal, S., 2009. Outsourcing business to cloud computing services: Opportunities and challenges. IEEE Internet Computing, 10(4), pp.1-17.
Motahari-Nehzad, Stephenson and Singhal, (2009) thinks that the Services oriented architecture is taking the business today to different heights.It has introduced virtual business in real world. The authors in here talk about such a business with all its functions being outsourced to the online services. Cloud computing provides bigger and smaller enterprises with IT technologies as services which are much more flexible, attractive, and affordable. It portrays cloud computing in two different ways which are layered computing and conceptual computing providing virtual business environment.
Authors find it more useful for the small business who cannot afford big IT Infrastructure and skilled IT teams to handle all the situation of errors. The small businesses can pay small values for it and can higher up their profit level without much capital investments. Usually the larger firms opt for the hybrid cloud services for running their critical application and storing confidential data in the private part of the cloud while using public for rest of their work. Motahari-Nehzad, Stephenson and Singhal, (2009) presses on the usage of cloud by overcoming those challenges which are evident like security, complexity and connectivity.
Gai, K. and Li, S., 2012, November. Towards cloud computing: a literature review on cloud computing and its development trends. In Multimedia Information Networking and Security (MINES), 2012 Fourth International Conference on (pp. 142-146). IEEE.
Gai and Li (2012) are evident abourt the changes that cloud computing has brought to the field of the Information and Technology. It defines cloud computing as an experience whre the virtual machine creates and effect on the user of a physical machine where the whole process goes on. The present article approves of the cost-benefits which the clouds offer free of cost. Data intensive application witnesses the need as they require running huge amount of computation. Gai and Li (2012) highlights some of the obvious or upcoming obstacles which may serve as great challenges for businesses namely data transfer issues, Scalable storage, software licensing, bugs in the largely distributed application, data lock-in problems and performance unpredictability.
However, the elasticity the whole process provides making it more and more tempting for the business. Yet, the authors think it to be huge success in perspective of business if the negatives and shortcomings are dealt with. Critically the designers can be the one who can overcome these obstacles by design such computers which can directly be deployed directly into the Cloud. Energy proportionality is another need which Cloud computing has to deal with.
Armbrust, M., Fox, A., Griffith, R., Joseph, A.D., Katz, R., Konwinski, A., Lee, G., Patterson, D., Rabkin, A., Stoica, I. and Zaharia, M., 2010. A view of cloud computing. Communications of the ACM, 53(4), pp.50-58.
Armbust et. al. (2010) finds it more comfortable for the Startups for using the cloud computing. The cloud computing provides advantages to the start-ups to build up their own data centre without much investment. This virtual data centre becomes a big valuable asset for the start-ups. Along with that the startups could also create their own fabrication lines too. Not only does it help the technological business but also other business needing huge data storage. This saves the organization from the danger of under-provisioning or over-provisioning.
Cloud computing sometime can be disadvantageous for the bigger enterprises who already own the data centers, IT infrastructure and networking for themselves. The companies having such features it becomes a bit expensive to pay for something which they already have. Yet there are some flexibility provided by the cloud vendors which serves them with extra piece of technology. Flash memory is said take the cloud computing to the whole new level. The authors emphasizes on the improvements of bandwidth for the usage of the computing. Armbust et. al. (2010) is optimistic about the upcoming future of clouds.
Hofmann, P. and Woods, D., 2010. Cloud computing: The limits of public clouds for business applications. IEEE Internet Computing, 14(6), pp.90-93.
Hofmann and Woods (2010) in their article emphasizes on the trade offs of cloud computing. A business when moving into with the cloud computation might face many obstacles in terms of security, Performance instability, lock-in issues and other such stifling Innovation. The author fears that it might stop or impair innovation. It may after some time just become a commodity and nothing more. Authors such claims ought not to be true yet his analysis points it towards the same. The growing IT market has actually resulted in the growth of cloud computing.
Hofmann and Woods (2010) does not mentions of much positive that the cloud co outing has brought in the way of running business. Latency and network limits along with security are seen as a big drawback. Fiber optical cable limits the speed of the network. Security becomes a issue as the enterprise requires to trust the provider itself for safety and does not promotes customizable security. They support the fact that the Cloud computing may not work like other electronic plug plays and will reach the heights only if they earn such effective measures.
Dillon, T., Wu, C. and Chang, E., 2010, April. Cloud computing: issues and challenges. In Advanced Information Networking and Applications (AINA), 2010 24th IEEE International Conference on (pp. 27-33). Ieee.
Dillon, Wu and Chang, (2010) brings out the issues and challenges that the cloud computing faces. The popularity and its acceptance in the market have been seen successful because of the flexibility that it promises. It is acclaimed that the cloud computing will change the whole scope of the IT Infra. The authors find it a bit vague because of the challenges and issues it raises. The article describes the Service-oriented computing and the other grid computing to better understand the barriers being the bottlenecks. Along with the benefits cloud computing the article entertains all the risks and challenges that are probable like data theft, No service level agreement provision, Cloud Interoperability issue and stifling innovation.
Dillon, Wu and Chang, (2010) discussed some of its solutions too which may solve some issues of this upcoming technology like through layering and hybrid cloud usage. The hybrid cloud works as two layered network providing Private and Public layer. The private layer protects the confidential data while the other outsources work at public with data not confidential. Such division protects the data and even gives the user full usage options.
Truong, D., 2010. How cloud computing enhances competitive advantages: A research model for small businesses. The Business Review, Cambridge, 15(1), pp.59-65.
According to Truong (2010), cloud computing services are responsible of providing the business today with power of using different model being provided by the providers in terms of hardware and software. It helps the business in two ways, firstly, reduces the stress of having build up whole infrastructure to support their business and secondly the cost spend. It promises of different set of applications being provided at low cost which were not possible earlier. The users enjoy the benefit of time saving, cost and reliability for the service. Small businesses are majorly profited as they receive scalable resources for small pay which works on their demand and can be removed or added on when asked.
Nevertheless, the Truong (2010), points out the gap that is the challenges which the small businesses will face in the adoption of Cloud computing. Some of them can be highlighted as Data integrity, privacy, audit trails, security and compatibility. These reasons points out towards the low rate of adoption. Truong (2010), believes that a company which uses it wisely may get profited through it while the other may degrade their performance in adoption of Cloud Computing.
Marston, S., Li, Z., Bandyopadhyay, S., Zhang, J. and Ghalsasi, A., 2011. Cloud computing—The business perspective. Decision support systems, 51(1), pp.176-189.
Marston et. al., (2011) considers Cloud Computing as Commodity for it s increasing demand ad lowering prices. The businesses today find it difficult to handle the IT infrastructure along with their running business as the importance of technology grows. Cloud Computing focuses on two main trends bringing them together at one place that is Business agility and IT efficiency. It efficiency here can also be seen as green computing by deploying computers and related technologies in places where cheap electricity is available. It providing immediate access to all sort of hardware without making any upfront investment is seen as its major advantage. It lowers down all the witnessed IT barriers which came in the way of growing business. It provides option to the companies of scaling their need for the services. The analysts can get access to the data that is public for their own researches.
Marston et. al., (2011) through SWOT analysis provides with some of the major weakness or disadvantages that the cloud computing confronts with. The prime weakness being the loss of controls over physical operations of the business along with that no information about the location of the business data storage. The low provision of Service level agreements make it more difficult for the businesses to rely on such a service. Marston et. al., (2011) concludes by addressing Cloud Computing as A technology which is here to stay.
