Question: Describe the key Concepts of Cloud Computing and why do you think that a move to the cloud will benefit Webb's Store. Answer: Introduction In one line Cloud Computing can be defined as a general term to deliver hosted services over the internet. It is applicable in various sectors including business in which it enables the companies to consume computer resources which can be listed as: applications, storage and virtual machines (VM) as a utility. IaaS Approach to Migrating Webbs Database to the Cloud IaaS (Infrastructure as a Service) is a self service model which can be implemented in Webbs to monitor, manage and access the data and information produced by all the stores situated at different places on the business. This will give access the employees at different stores to achieve business calculations and produce outputs faster (Gueye et al., 2014). IaaS provides full access to the users about the runtime, data, and middleware of the applications being used for different operations. It is a package provided by various service providers which can be easily purchased and a user can enjoy the benefits like cloud storage, quick computation and many more. PaaS Approach to Migrating Webbs Database to the Cloud PaaS (Platform as a Service) is also another architect of cloud computing which can provide Webbs a better framework of how and what applications are needed for the daily operations of stores of Webbs. It is an appropriate service for developing, testing and deploying applications which can have positive impact on Webbs in simple and cost-effective way (McGrath, 2012). PaaS applications inherit various cloud characteristics, some of them are, scalability of storage, SaaS enablement, on-demand availability, etc. This is a completely hosted system in which customer is not responsible for any data updates and miscalculation. Advantages and Disadvantages of IaaS and PaaS approaches Advantages (IaaS) Advantages (Paas) Disadvantages (IaaS) Disadvantages (Paas) Most secure Cloud services as compared to any service Full control to users to the processing data and Virtual machine (VM) (Sadiku, Mussa Momoh, 2014). Proper user interface and access to the middleware. Cost-effective as compared to IaaS Allows user to run application of their interest (Mollah, Islam Islam, 2012). Hosted network is provided by services so users are free of allegation for any miscalculation or wrong data input. Customers feed the data input into the database makes only user responsible for any backup and other management system Less control over the physical location of the database. Not much cost-effective than PaaS Security risk Security lead to the privacy risk to the information and data saved in the database In this service tasks that include management are more time consuming than another services. Recommended Approach Based on the above table which relates advantages, disadvantages of IaaS and PaaS approaches it can be said that IaaS is a better approach for Webbs management system. Stores located at different places ca also have access to these applications and can upload their data over the internet or cloud. This will help the directors to monitor and plan the next steps which need to be taken in order to benefits the Webbs. Excluding the expensive cost disadvantage rest of the disadvantages will not hamper much to Webbs, so advantages are sufficient enough to implement this approach. Conclusion The information presented in the above report is enough to conclude that cloud computing can change the face of the management of Webbs by allowing users to use various effective and efficient applications provided in IaaS services. This approach will help in leading Webbs to achieve its goals References: Gueye, A. D., Sanogo, I., Ouya, S., Saliah-Hassane, H., Lishou, C. (2014).
