Literature Review For Cloud Computing

Important Variables

Discuss about the Literature Review for Cloud Computing.

Cloud computing is the mechanism which can be adopted by the business organizations for many of the purposes such as delivery of computing services—servers, storing of databases, networking, software and systems which can be used by the entities in a number of operations, analytics and more over the Internet. The business organizations or the institutions who provides these kinds of computing services are (azure.microsoft. 2017) known as cloud providers and these institutions charge for the services they provide and these charges or the fees are based on the usage of the systems and the mechanisms.

According to Helpdesk LLC (2017) the small and large business corporations have been waiting for the cloud computing systems from the last few years. The most of the business organizations face the confusion and have a doubt regarding for making use of this system. The below mentioned literature review has been presented by the Help-desk LLC for defining the system and also determination of the same system will be done (Reilly, Wren and Berry, 2011). First a description has been given about Cloud computing is the same concept as it was earlier just the change and modification has been done in the name of the concept. This concept has been used by many of the business corporations and institutions from many years. There are a number of small business enterprises which are found to be using these mechanism and which are found with a server which is connected with a number of computers and these desktops are networked to server. And the second system which is used is known as hardware layer and which is also typically referred to as “the network,” or “the information systems.” And the cloud computing has decreased the need of networking in the offices at a greater extent. There are numerous of benefits of making use of this system or mechanism and from them one is that cloud computing will benefit the network and as it can be suddenly accessible from anywhere and anyone one can have access to the Internet and by which the company will be in running condition all time all the operational activities will be in a continuous form. And the biggest benefit of this system is that it can be accessed from whatever device or mechanism used from any to have with you – i.e. laptop, iPad®, mobile phone, etc. A comparable reference point would be Google Docs (Pocatilu, Alecu and Vetrici, 2010).  The following is one of the example of a common use of cloud computing is while submitting of your documents to Google Docs for others to access via the Internet. For the initial level the most suitable example which is suitable for this system is of average small business person. As the business is small scale business the owner won’t be having big amount for investing and building up an in-house network and also the entire business operations should b the entire business operation can be up and run-up and running within short period of time and this could be made happen by making use of the approach of cloud computing. The expenses are basically pay-as-you-go means as per the use and are also based on the amount of storage space and computing power that you use (Antonopoulos and Gillam, 2010). The below mentioned are the advantages and drawbacks of cloud computing:

Low Cost – Emergence of the mechanism of cloud computing in the market has been considered as the a low-cost or minimum expense incurring tool for the business. Corporations.  And also business organizations are not required to make huge investments and heavy expenses on the establishment and setting up of this mechanism, as no hardware, equipment and infrastructure establishment is required. The companies won’t be requiring incurring the expenses for installing the desktops, laptops or some type of device to access the Internet and utilize your data. And the investment in the implementation and maintaining the private and the company’s own in-house networking is very minimum or low (searchcloudcomputing.techtarget. 2017). It is a very vital and significant concept for many small scale business corporations. The expenses incurred in the maintenance of an in-house network are enormous and it has also been observed that they are increasing every day. With an in-house network, there are other related costs and expenses which are incurred and are required to be paid by for the installation of the software and hardware upgrades and also the maintenance and providing training on the related topics to the employees. The above mentioned responsibilities and the duties are to be fulfilled by the service providers of the cloud systems and also the costs and the expenses are to be incurred by them only.  The best way to develop an understanding which is related to the concept of expenses computing services is to think in context of renting vs. owning. The service providers of the cloud computing services should have a storage of all the required resources and which are to be utilized by the business client for a monthly or annual fee which has been charged by the service provider at the begining. And this concept has been referred as similar and which is also common to as the Software-as-a-Service (or SaaS) model. In this concept the company is required to pay for the use of the service which can also be said as you pay as you go. A sense of more predictability in budgeting for these costs and expenses is provided to the owner of the model.

Flexibility — With the use of the mechanism of cloud computing in the business organization, as mentioned above the company need to pay only for what the company use the services, the business corporation are provided with a limited flexibility in the use of the system and the service for which they have already paid an amount. For instance if a person has small amount of investments for starting up a small business and in this case the owners can make use of small computing packages and can also increase the use of the computing services as the business  activities and the operations keeps on growing. After a particular growth in the business the owners can opt for a bigger package of computing services (Velte and et al, 2010). The setting-up, implementation and bring into operation are some of the functionalities and these are done with a good speed. There are some service providers who have set-up at an automatic scale for the essential and required resource for the business corporation. Necessary changes and modifications can be done in the infrastructure as per the requirements of the organization. These modifications can be into making the network private network, public, or a combination of both (Sosinsky, 2010).

Simple, Fast, Easy – The biggest advantage of cloud computing is that it’s is of very much easy to operate. By making use of the system of cloud computing can streamline many parts within the organizational structure of the entity (Griffith. 2016). It will be proven beneficial for the business entities when they start making use of these systems and step into the systems and this will also make the business to run more smoothly with a great potential and also improves the efficiency of the firm and also when the firm is a web-based corporation applications that are available in the cloud (Rittinghouse and Ransome, 2016). Everything from prospect management applications to customer billing and invoicing can be moved out of the store of the company and gets shifted to the into the cloud system. This gives will enhance the ability to focus on what the company do best in business and excel and grow the strengths while someone else handles the administrative functions (Sotto, Treacy and McLellan, 2010).

Accessibility — Regardless of where the company stands or is operating in the world, it will have access on the operations which are based on cloud computing mechanism. There will be only some sought of complicated remote login procedures and which are required for the in-house network. In this process the only thing or the tool required is a device that can access the web and an Internet connection which will be controlling the systems (bigdata-madesimple. 2017). This means the employees or the staff in the organization can have access anywhere and at any-time, from home, office or on the road at a client’s office.

Sustainability – There are a number of issues which can be faced by the business such as a natural disaster which can strike the business at any time,. But now there is solution to the problem which is cloud computing capability which resides somewhere else. Obviously, this is can also be considered as a disadvantage if the disaster hits the service provider (Chaczko and et al, 2011).

Security of Your Data — This has been considered as the prime or the main concern which is related to cloud computing systems which are being used within the business organizations. In a very basic sense, the data or the confidential information that used to reside within the four walls of the business corporation now resides elsewhere. Addressing the security of the data must be done on priority basis and also the security of that data must be addressed and shit should be considered as a significant point and this is required to be done with care as the data stored in the cloud systems contains trade secrets of a number of business organizations, proprietary lists, files of the consumers and their records etc. As per the researches and survey carried about 69% of cloud providers said that data security was the responsibility of the end-user (Antonopoulos and Gillam, 2010). And on the basis of another survey it was also concluded that by contrast an approx. estimate number of only 35% of the end-users agreed that they should be held responsible. And it has been clearly mentioned that there is a sense of disparity between cloud providers and cloud users about who is responsible for data security. The companies who are making use of the cloud computing system should have a clear idea and estimate that their data is vulnerable to compromise and is exposed to risk. Author has also mentioned that knowing about the risks and dangers and also having an idea about the proper measures and precautions which are required to be taken right from the start has been considered as an important step for the business organization (Vishwanathan, P, 2017). Whereas there are a number of small business organizations who do not have the resources to adequately protect their data even when it is in-house and for these small companies a reasonably priced off-site solution may be right for certain applications (levelcloud. 2017). The key or the solution to this problem is consulting or asking to the right questions of the provider and getting good advice.

Costs When Under Attack – As mentioned above the mechanism of cloud computing has been considered as a low cost mechanism or tool and some time it also provides some sought of additional benefits. But it can also actually cost more money or can be a reason in incurring a number of additional expenses. For instance, if a company’s website comes under a distributed denial of service (D-DOS) attack (stratospherenetworks . 2017). The reason behind this attack is that the typical goal of a D-DOS attack is to gobble up resources and which is done for rendering the server incapacitated (Sridhar, 2009). If the cloud computing provider has no protections in place against DDoS attacks, when the site is attacked, then service provider will have to simply begin to increase the resources that the site requires (due to the attack) and bill for the resources provided and which naturally will bring an increase in the expenses. It is of very much significance for the business corporation to ask the provider what kind of provisions they have to protect against this type of attack.

Performance Can Vary — In a cloud environment, the applications which are running on servers for the business organizations are also simultaneously providing resources to other businesses too. With the fluctuations in the requirements and the demands made by the other users, there will be impacts on the performance of the business organization and the share of the resources will be also on a varying note. Often, the service providers may claim that the resources available with the business entities are unlimited. This may be theoretically true, but from a practical point of view the hardware scalability is probably limited.

There are number of methods which have been adopted for carrying out the research of the above presented literature review. Mainly the books have been made in use for getting a deep understanding about the advantages and disadvantages of the cloud computing mechanism. Also the articles have been used for get a clear idea about the concept.

In the above carried out research the main focus has been provided on the concept of cloud computing and also the advantages and disadvantages of the system. Mainly the focus of the research is on the benefits attained by the cloud computing system and which develops the gap in literature review as some of the important issues or disadvantages has been ignored. Such as reliability of the organizations on the system is too much and is increasing day by day and which is a big issue as in case if the system crashes or is hacked then the corporation can be in a big problem. As all the confidential data is stored within the system. Also there is very limited control over the whole system of cloud computing. The more control is of the service provider and which can be sometimes quite dangerous for the customer as many of the details can be exposed to the service provider.

Conclusion 

From the above carried out research it has been concluded that the concept of cloud computing has to be considered as a new concept in terms of maturity and adoption. And also there are some expectations and estimations made regarding the changes under which the business corporations will undergo in the future, in terms of resources, issues, risks, and ultimately best practices and standards. Moreover there are a number of benefits and advantages which have been provided by the system and have also been undergone in providing potentially values for institutions of higher education and other business organizations. On-demand services can resonate positively with the current university tight budgets across the nation and other parts of the world. A number of benefits of the transition to cloud computing have been mentioned out in this above carried out analysis along with concerns regarding the general implementation of this application.
