Question: Discuss about the Essentials of Computer Organization and Architecture. Answer: Introduction Cloud-based storage can be defined as the specific model of storing data where the digital data gets stored. The hosting company is responsible for managing and controlling this cloud based storage (Laan 2017). Each and every provider of the cloud based storage helps to maintain the accessibility and availability of the data. The physical environment is extremely protected with this cloud storage. These types of storage providers manage the data on storage servers. Virtualization techniques are responsible for building all the storage servers of cloud storage. The following report demonstrates a brief overview on the concept of cloud based storages. The report provides the background of the topic by describing the history of the topic. The methodology and the research details are also described here. The advantages and disadvantages of cloud based storage are also given here. A conclusion will be drawn on the findings. In the year 1960, Joseph Carl Robnett Licklider invented cloud computing by while working with ARPANET. He wanted a connection between data and people from anywhere and at any time. In the year 1983, CompuServe offered all of its users with a smaller disk space for storing all types of files that are to be uploaded (Lee 2014). In the year 1994, the first storage was launched and it was completely web based. In the year 2006, Amazon Web Services or AWS first invented the cloud storage, namely AWS S3. It was instantly recognized by everyone worldwide. The best examples of cloud based storages in todays world are Google Drive, iCloud, Google Docs, XDrive and many more. Cloud based storage comprises of various significant advantages and disadvantages (Null and Labor 2014). These advantages or benefits of cloud storage has made the storage extremely popular and accepted by all. However, there are some of the major disadvantages as well. These disadvantages can be dangerous for any enterprise or company. Methodology is the theoretical or systematic analysis of any method that is used to execute a specific action or activity. This report is done with the help of qualitative research methodology. Several journal papers, books, conference papers and various peer reviewed articles were reviewed while making the report. Amongst them, twelve articles were selected and the report is made on them. These articles are being used to define the topic of cloud storage and its advantages and disadvantages. Issues, Various Points of View According to Stefanov and Shi 2013, cloud storage is extremely necessary and secured to give high performance in data storage. It helps to maintain the security and privacy of the data and thus can be termed as secured. As per Lee 2014, cloud networking is the most important architecture for the cloud based networks. Rountree and Castrillo 2013 have discussed about the various advantages and disadvantages of cloud based storage in their paper. They have mentioned about the importance of cloud storage for any storing any data. As per Laan 2017, the infrastructure architecture is vital and thus should be maintained properly. The cloud architecture includes IaaS, PaaS and SaaS. Each and every cloud architecture has its own advantages and disadvantages. Cloud based storage is one of the most important and significant storages of data that is utilized by the cloud providers to properly maintain, control, manage and backing up of data (Kurose and Ross 2016). This particular service allows all of its users in storing as well as utilizing the files online, so that these data could be easily accessed from any part of the world with the help of the Internet. It has been observed that over 800 decision makers in business have been benefitted from cloud storage and they have gained competitive advantages through this. The most significant advantages of this cloud based storage are as follows: Usability: The very first benefit of any specific cloud storage is its usability. This type of service can be easily utilized and accessed from anywhere and on any operating system. This particular feature makes the cloud based storage extremely popular and accepted by all. However, this usability of the cloud storage is restricted to authenticated users only ad thus it is extremely safe and secured. Cost Effectiveness: This is the second most important advantage of cloud based storage. There are several cloud based storages available in the market and most of them are extremely cheaper in comparison to other data storages. The cost effectiveness of the cloud based storages helps them to gain popularity (Rountree and Castrillo 2013). Moreover, all the organizations that are utilizing the cloud storage get benefit from it as it helps in the reduction of annual operation costs and this cost around 3 percent gigabytes in storing the entire internally. The users would be able to get the additional cost savings since it does not require any type of internal power for the purpose of storing the information remotely. Disaster Recovery: The third important advantage of the cloud storage is the disaster recovery. The organizations or the companies that do not have the emergency back up plans; cloud storage would be the best answer to all of them. The cloud storage is responsible for all types of emergency back ups in case of any data breaching or data lost. These cloud storages act as secondary copy of all kinds of important files that has the highest tendency to be breached or hacked by the hackers or intruders (White 2015). Cloud storage helps these organizations by storing the confidential files in a specific remote location that could only be accessed by the Internet. The hackers do not get any hold of this location and thus the data is extremely safe and secured. Moreover, due to the remote location, and access from only the Internet, the disaster is very less and even if disaster occurs, it can be easily recovered without any complexities. Accessibility: The fourth important advantage of any particular cloud storage is its accessibility. The files that are being stored within the cloud based storage can be easily accessible from any part of the cloud. Moreover, this hassle free accessibility has helped the cloud storage to become extremely popular and acceptable by all its users (Stallings and Case 2013). Any particular user, who are accessing through the Internet, can access the data that has been stored in the cloud storage. These above mentioned advantages or benefits help the cloud based storage to be excessively advantageous and important for the users of cloud computing. Although, cloud based storage comprises of various important advantages, there are some of the major disadvantages embedded within the system as well. The most significant disadvantages or demerits of any cloud based storage are as follows: i) Security: This is the most significant disadvantage of cloud storage. In spite of providing various advantages of data storage, the security of this particular storage is threatening (Laan 2013). It has a disaster recovery embedded within it, however, the security system is not at all up graded and thus there is always a high chance of data losses in any cloud storage. Various security measures are adopted for mitigating the security risks or threats but still the threats in the data recovery is not removed completely. ii) Moving of Documents: Two types of operations are used in cloud storage while moving any document from one location to another. The two operations are the dragging and dropping of files. If not done carefully, the movement of data can be permanent and thus the data would be stored win the cloud storage forever (Pfleeger and Pfleeger 2015). There should be a second copy of data while it is being stored within the storage. Bandwidth: The third disadvantage of the cloud storage is that various such services have particular allowance of bandwidth. If any user crosses that allowance, additional charges are to be incurred. The companies often give a second thought while using any cloud storage. Software: The fourth disadvantage of cloud storage is that all the services and software are to be downloaded in each and every device (Santana 2013). From the above report, it has been found that cloud based storage is very important and significant storage of any data through the Internet. The providers of cloud computing help the users to store their data effectively and efficiently. It is an online storage that comprises of several significant advantages like usability, cost effectiveness, accessibility and disaster recovery (Burd 2016). However, few disadvantages are also present within the storage like the bandwidth is restricted, the requirement of down loading software, the lack of security and the problem in moving any documents. The journal papers and articles have helped to understand the entire concept perfectly. Conclusion Therefore, form the above discussion it can be concluded that cloud computing is the practice of transferring any data or confidential information through the Internet. It is a paradigm of information technology, which helps to enable the ubiquitous access to all types of shared pool of system resources. These could be rapidly provisioned by lesser management effort on the Internet. Cloud storage is the storage of cloud computing that is utilized for storing data or any confidential information with extreme security and safety. There are several kinds of cloud based storages available in the market. The above report has outlined a brief discussion on the cloud storage and various advantages and disadvantages. This report has provided the proper analysis of the methodology, research details and issues of cloud storage. Furthermore, the findings are also mentioned in the report. References Burd, S., 2016.
