This paper explores cloud computing and its own merits and de-merits which may help a business in taking a wise decision either in favor of it or against it. Cloud computing may be the buzz word now in neuro-scientific information technology. It is the concept of where an organization has its data and application hosted on an authorized infrastructure. Often the applications were created and developed by the service agency and the company using it uses that software against its data. There are various factors for deciding and only it in addition to several factors that raise strong inquiries for its acceptance. It is totally based on the need of the business, whether it leverages cloud computing or not.
What is Cloud Computing?
Cloud computing is Internet-based utility computing, basically shared resources, software and information that are being used by end-users hosted on digital servers. Some persons term anything beyond a businesses or user’s personal firewall to maintain cloud (Knorr, Gruman, n.d., para. 2).Personal computing has progressed in three phases. The first phase was where the data and software was stored on a local desktop. The second phase is where in fact the applications reside on an area server and utility application on the desktop along with the internet to supply valuable information. The 3rd phase is where almost all of the data and application will reside anywhere on the internet. This phase is determined as cloud computing. Although a lot more than 80% of world-vast computational data is being predicted to go into clouds within the next five to a decade, there are a variety of unanswered questions which will decide the velocity of advancement in this arena (Nelson, 2009, para. 1). It is just a new concept in the field of information technology still trying to get acceptance, where-in the technological services/ applications are provided by a third-party.
Cloud Computing – Nomenclature
From the days when utilization of internet started becoming well-known, the network architecture diagrams demonstrate internet as cloud to hide the complexities from the end-user – hence the brand cloud processing. The applications/ software are provided as services which reside in data centers with server farms and redundant storage area. End-users can access them via browsers in notebook computers or hand-held equipment. Google Apps, Facebook and salesforce.com are examples of cloud computing which have become very popular especially with the younger generations. An extremely basic exemplory case of cloud computing is a web-centered email services like Gmail where in fact the complexity of safe-keeping and presentation of customer data is supplied by an authorized, and users happen to be leveraging them by way of web browsers(Nelson, 2009, para. 12).
Benefits of Cloud Computing
Cloud Computing is a totally diverse paradigm of personal and also corporate computing which drifts away from the traditional software business design. There are many positive factors for deciding and only moving to cloud processing. A number of the important favorable factors are discussed below. Access cost for a business to create itself up in cloud is much less in comparison to traditional setup. Price for running IT (IT) business in cloud world could be visualized as operational price. Organizations no longer need to fork out big amounts for equipment and software upgrades (Cunningham & Wilkins, 2009, p. 3). They no more need to worry about end of existence for hardware/ software. Businesses no longer need to spend large sums on buying new hardware for scalability. In short, infrastructure costs to get in to cloud are lower than that for the original model. Pricing is normally based on use options. Organizations do not need to maintain a workforce of IT persons and can give attention to strengthening their organization domain knowledge.
Organizations can use only applications which are fitted to their need rather than pay huge amounts on licenses for utilizing a software suite. Usually buying a application suite is of lesser value from the business enterprise perspective as just few top features of the suite are actually used and the price connected with upgrades and licenses are costly. With canned applications in cloud, organization can decide and pay for just the applications that they need. Using virtualization as the primary technology, additional computing resources could be added dynamically with no any downtime. By monitoring peak load and server use, an application can be dynamically switched over to a virtual machine with greater computing quickness or the existing virtual machine can be augmented with more computing assets (Zhong, Wo, Li & Li, 2010, p. 2). The business using the application doesn’t need to give extra for the scalability feature. In virtualization, high performance servers are put into multiple machines catering to different buyers. Some of the popular products will be VMware and XEN. With the infrastructure being found in multiple data centers and huge server farms, users could be productive anytime from anywhere in the world using web-browsers in laptop computers, desktops or hand-held gadgets. Business executives travelling to client locations do not need to carry hard copies and everything with them, as with a simple click of the mouse they can reach the information gateway how to write a summary paper: there’s nothing simpler.
With infrastructure being preserved at multiple redundant sites, it offers more confidence to business organizations in regards to business continuity and disaster restoration. Nowadays in the market, one of many buzz text is collaboration. Tools like sharepoint are becoming very popular where multiple people could work on the same document and gain access to them without having to store the record locally and focus on it and send out it via email for edits by different users. With blogging platforms 2.0 where everything will likely be on the web, collaboration will be super easy and straightforward (Cunningham & Wilkins, 2009, p. 4). Because the infrastructure for cloud computing is centralized and the client is a thin consumer like a web-web browser or a WAP browser, the upgrade and repair of the system is much easier when compared to system where we need a desktop client connecting to a server where each consumer desktop must be improved when the server type is getting upgraded (Cunningham & Wilkins, 2009, p. 3).
Concerns with Cloud Computing
As there is certainly darkness after light similarly with the benefits discussed in the earlier sections there are many concerns going swimming with the acceptance and utilization of cloud processing. With the applications presented as service and being utilized by different customers, personalization appears to be one limitation. The characteristics are similar to a COTS product but if proper negotiations are made, product-based companies the majority of the time do allow customization. There is a serious concern with info getting centralized and out of business control. Sensitive info will now be beneath the control of a third-party and according for some experts that is a compliance issue plus some feel that that is likely to be the finish of confidential records administration (Cunningham & Wilkins, 2009, p. 7). With regards to the disclosure plans, some persons do not know where you can draw the series and knowingly or unknowingly share essential information and with data from the third-get together space that concern becomes even more critical. With everything accessible through internet, organization will be totally dependent on the network and the provider provider’s infrastructure. Business will come to a halt if the network/ internet are straight down. As illustrated by Patrick Cunningham in his document (2009), currently in the IT community whenever we need to troubleshoot an issue, one advantage inside our favor is that the application form logs and the data source answering the question: how long should a college essay be? are within the premises of the business. With the change to cloud, this aspect will be lost and so special support or agreement binding needs will be there between the service provider and the business for e-discovery. With organization sensitive internal data being maintained by the vendor the dependency on the vendor’s unique API and proprietary interfaces could create a practical lock-in with owner. If under some circumstance the business enterprise is dissatisfied with the vendor, moving to a fresh vendor means data must be reformatted and converted which is often frustrating and expensive (Brandel, 2009, p.1).
Return on Investment
By going to cloud processing companies can save huge amount of cash. As illustrated by Raichura (2009), in couple of online articles please discover below charts showing types of savings that an organization can achieve by moving to the cloud. The first desk illustrates the difference in cost of having infrastructure on premises versus having it in the cloud. The next table illustrates the cost saving considering storage, service, infrastructure and platform in the cloud.
After having mentioned the merits and de-merits it obviously stands out that there is no one clear solution in favor or against of cloud processing. So far it seems that will be a hybrid solution from the organization standpoint. Some critical, organization sensitive applications will continue with the traditional business model till the concerns about privacy and legal issues will be cleared from cloud processing whereas straightforward canned applications will become more and more famous in the cloud space. The idea and technology is here to stay but it nonetheless in its infancy and there’s a long road ahead to get to maturity.
