Question:
Make a Report on Current Challenges Facing the ICT Professional.
Cloud computing earlier appeared in 1996, it was earlier mentioned by the Compaq internal document. The term was traced in 2006 when Elastic Compute Cloud. It was introduced by Amazon. Massive computing energy is needed to grow business and competitive advantage [Orban and Lui, 2008]. Earlier an organization used to load their data is to use their computing power for their data centers. But, using their own data center for processing of the data is costly and it is also very complicated. The cloud computing was a substitute for this. It is the term that is used for a computing service, which is based on internet. It was launched by big organizations like Amazon and Google, etc. in 2006. It serves a computing service whenever you need it, it is also of low maintenance and also it can be implemented quickly. It uses less staff of IT, which helps in cost reduction. These were the promises made by the cloud computing few years ago. It was assumed and calculated by the IDC that cloud spending will hike from 16 billion USD (2008) to 42 billion USD (2012) [Leavitt, 2009]. It is in the top ten issues for CIOs recognized by the commentators like the VP [Preston, 2011].
The increase in the growth of the same is making it a great topic for research. We make a current view of the research, some suggested that we should give more efforts to focus on the future to do consumer research [Robey, 1998].
In this section, cloud computing is introduced, and it is differentiated with technologies like grid computing. Cloud computing, it is stated as 5th utility, with electricity, telephone, gas and water. This service is available in society [Buvya, Venugopal, 2009]. This is not a new vision. In 1961 John McCarthy predicted that in future cloud computing will be publicly utilized. [Wheeler and Waggener, 2009].
It is a way of computing, it has capabilities that are related to IT are massively scalable. This service is provided over the internet to multiple users. Gartner [Smith, Bittman, Scott, et al., 2009]. Cloud computing is a collection of conceptual, highly scalable and controlled infrastructure which is capable of hosting end user application and billed according to its consumption. Forrester [Staten, 2008]Cloud computing is in demand technology which has unlimited resources, the elimination of up-front commitments by cloud users.. It is a short term basis service in which user has to pay only for resources which are being used. [Armbrust, Griffith, Joseph, Konwinski, et al., 2009]. Cloud computing has cyber infrastructure, it is virtual distributed computing, utility computing, grid computing, software service and web service. [Vouk, 2008]. It’s a category of distributed as well as parallel system having a collection of virtualized computers that are connected with each other. These are dynamically provisioned. These are represented as a single or multiple computing resources. Agreements are based on service level. These agreements are based on the debate or talks between cloud service provider and users [Buyya, 2009].
Marc Benioff, said that on-going technologies have many years of investment of billions of dollars on their side and that the cloud computing is risky, unproven and light weight
Stephen Elop, convinced that the cloud computing can be future technology, also states that The convenience of increase in productivity, improved efficiency and cost savings, with the power to support and authorize a broader range of users via the cloud are clear.
The issues are also related to cloud service providers:
The factors that affect the location of data centers of cloud computing resolve the jurisdictional issues. The policies of the same can have an impact on cloud user as well as the provider. With these governments can suffocate as well as promote the development of this computing system. There are same policy problems with cloud computing, which could be a problem for the user as well as the provider of cloud computing (Jaeger, 2008).
Conclusion
Cloud computing service is very beneficial for business purposes and also we can share information across the globe. It also reduces cost for users and providers. Whenever we can access the internet we can access the data and information with the help of cloud computing on the other hand without connection we cannot access it. There is also the risk of unauthorized access or theft of data. But it gives quicker access to data. No more data are needed to be stored on a device, which reduces the cost on user side. It is available on each internet access device, which makes it easier for user to use it anywhere and on any device.
Cloud computing is obviously not risk free, but it is manageable. If some facts are considered such as not sharing any personal information that can help an unauthorized person to access the data, and also considering the fact that internet access is available all the, so that data can be accessed whenever it is needed. So, we can conclude that cloud computing is a very efficient technology and can be very useful for business or personal use in the future.
