Cloud computing is a service where an individual can acquire computer resources and networked storage space. One can access information from anywhere at anytime through a cloud. A cloud consists of both the software and hardware which is important for running applications. For a cloud to work efficiently, one must have an internet connection. If one is looking for a particular document that is stored in the cloud, there must be an internet connection either through a mobile broad brand connection or wireless internet (Lewis et al, 2009). The advantage of cloud computing is that the same document can be accessed by any device as long as there is internet availability. These devices can be a phone, laptop.tablet or a desktop. This helps an organization to work more with ease because a cloud can access software and store data. There are several types of clouds that can be subscribed depending on ones needs. One of them is a private cloud, which is established for a specific organization or group and access is limited. A public cloud can be accessed by any user with an internet connection. On the other hand, community cloud is usually shared among two or more organizations that have similar cloud requirements. A hybrid cloud is a combination of two clouds in which the clouds in particular are a mixture of community,private and public (Jansen, 2011). Literature review Rittinghouse,J.W., & Ransome,J.F. (2010). Cloud Computing Implementation, Management, and Security. New York: Taylor and Francis Group. claim that each provider serves a role and it gives users more or less control over their cloud depending on the type. When choosing a provider, one has to compare needs to the cloud services which are available. The cloud needs usually vary depending on how one intends to use the resources and the storage space associated with the specific cloud. A cloud provider becomes more expensive depending on an individual's technological needs. There are three types of cloud providers that one can subscribe to : infrastructure as a service, platform as a service and software as a service. Software as a service gives subscribers an opportunity to access both applications and resources. It makes it unnecessary for one to have a physical copy of softwares to install on the devices. This type of cloud provider makes it possible to have the same software to all devices at once by accessing it via the cloud. Under a platform as a service,this system goes a level above the software as a service setup. This provider gives its subscribers access to the components that they require to operate and develop over the internet. Fatih Erkoc, Serhat Bahadir Kert (2010). Cloud Computing For Distributed University Campus: A Prototype Suggestion, by Mehmet indicate that infrastructure as a service deals with computational infrastructure. In his system, a provider completely outsources storage and resources, such as software and hardware. By subscribing to this type of service cloud,one would be able to maintain his or her business with a larger computational capability. One has to spend more resources on the operation and development of applications. Most information stored on the cloud is often seen as a treasure to individuals with mean intent. There is a lot of confidential and private information that individuals store on their computers and this information is now being transferred to the cloud (Strowd, 2010). One has to be careful with the cloud provider he or she chooses. This is because security measures usually vary from one provider to the other. Research Question / Hypothesis One of the ways that service providers are addressing security concerns is with a private cloud that seems to operate behind a company’s the existing firewall. How does this work? Theoretical Framework More often than not people, people tend to be binary about the way they assess the private cloud which is known to be more secure as opposed to the public cloud which is not. However, this should not be the case. Most of the enterprises that operate behind the existing firewall can reduce the risk of security issues, but it does not completely eliminate or mitigate all these issues. A highly virtualized cloud or environment within the firewalls require a new set of security test. It is important to note that it is not possible to physically contain the system application and the data behind the virtual LAN or the manual separation of devices (Lewis $ Grace 2011) . The private cloud is known to provide a greater sense of security due to the fact they operate behind the firewall, however it is not a panacea. Generally, security is a real concern as it closely relates to the public available cloud service. In addition, the service providers seem to be responding to the innovative approaches like the virtual private cloud and client partitions that are within the public cloud environment. Nonetheless, security is still the single issue that is precluding more rapid adoption of clouding service. Quantitative Research Methods The qualitative research methodology that has been chosen in this context as the main aim of this research that is to evaluate the role of cloud computing of software organization and understand the perspective of choosing the different cloud technologies against the data security (Behrend rt al , 2011). There are lots of issues with regards to cloud computing data security of the clients that seems to be having doubts regarding their data security and most of the clients prefer a third party service providers to make sure that their data security. This approach works fine for large organizations and most of the small organizations will not effort a third party for the data security across cloud computing . Qualitative Research Methods Security concerns about cloud computing seems to be heightened by misconceptions that are related to security and compliance risks. Unfortunately, these security concerns are seldom expressed quantifiable. To clarify the issue of cloud computing security, compliance and business risk, qualitative research that focused on the risk vectors was drawn from interviews with top IT leaders (Peter J. & Kent B., 2010). The qualitative aspect of this research was used to separate facts from suspicions that would create a framework that would help align the perceived risk of cloud computing. The qualitative research method conducted a survey about the perception of cloud computing using the Likert Scale. Discussion The information housed on the cloud is more often seen as valuable to the individuals that have malicious intent. There is a lot of personal information and personal security data that people tend to store in their computer and this information is currently being transferred to the cloud. (Escalante, 2010) Therefore, this makes it critical for one to understand the security measures that your cloud provider has in place and it is equally imperative to take some personal precautions to be able to secure personal data. The most important thing that one must look into is the security measures that the cloud provider has put in place. This will vary from one provider to the next and also the types of clouds that are being provided. The encryption methods that the cloud computing methods should also be explained. The methods of protection that they have to protect the actual hardware is also important to determine (Zhang Tao 2011). In case of a break in or loss of data, they should have a back up for personal data. In case you have chosen a community cloud, the barriers that will help to keep your information separate from other companies is imperative. No matter how careful you are with your personal data, by subscribing to the cloud you will be giving up some control to an external source. Conclusion In summary, the cloud provides many options for the everyday computer user as well as small and big businesses. It opens up the world of computing to a much broader range of uses and increases the ease of use by giving access through any internet connection. However, cloud computing has some of its drawbacks. The client will have less control over who has access to your information and little knowledge of where it is stored. One should also be aware of the security risks of having data stored on the cloud. This can be a target for malicious individual and may have disadvantages as people can assess it through an unsecured internet connection. If you are considering to use the cloud, be certian that you identify what information that you will be putting out on the cloud, who will have access to that information and a guarantee that it is protected.The type of cloud and the service provider are also important things hat you should factored in.
