Virtualization and Cloud Computing for Webb Store-myassignmenthelp

Question: Discuss about theVirtualization and Cloud Computing for Webb Store. Answer: The advantages that Webbs can achieve if they uses the SaaS services Based on the type of business most of the software development business organizations uses SaaS, PaaS and IaaS cloud models to offer a much better data management approach to the employees and secured outcome to the consumers. However, due to lack of management approaches these companies might face major level issues (Kalloniatis et al., 2014). A great cost effective alternative and secured service could be served with the help of cloud computing and virtualization application. The advantages of Webb stores company after adopting the cloud computing are as follows: Affordability: The SaaS model provides affordable subscription based services to the consumers like CRM. With the help of this application the users will be able to afford the service (Toosi, Calheiros Buyya, 2014). With the help of the subscription the employees and users will be able to get automated upgraded latest system, maintenance and high degree customer support. SaaS model gives monthly based subscription model to the consumers. Quick deployment: The SaaS solution requires web browser and internet service together. The SaaS solution needs extra time to deploy the system in the organization however no software solution is required to be installed by the company (Zhao, Li Liu, 2014). The employees of the company will be able to access data from the server very frequently. Zero level infrastructures: During the delivery of the business operation and functional operations. The system IT infrastructure level complexities could be completely minimized with the help of the SaaS model (Grover Sharma, 2014). The SaaS vendor takes care of the system operation and hardware maintenance as well thus the employees and system developer need not to take care of any of the application. Data backup and disaster recovery: The SaaS model is able to provide data backup and even if any of the data get destroyed then that could also be retrieved easily by the employees and service providers (Jain Mahajan, 2017). If the server gets interrupted then SaaS model cab also provides disaster recovery option to the system developers. The disadvantages that Webbs can achieve if they uses the SaaS services Less of control: Each of the in-house software provides higher degree control feature to the system owners but hosted solution turns much of the control to the third party service providers (Pahl Xiong, 2013). Thus, in this case due to lack of trust most of the owners feel insecure to utilize this platform to serve their application. Application limitation: Currently due to the presence of high level beneficial outcome most of the medium to small business organizations are using the SaaS cloud model. However, still certain software applications are there that is unable to provide hosted platform to the consumers (Pfaff Ries, 2014). Still the company will be able to host some of the software if they found to be using the multiple software solution. Slower speed: The speeds of the SaaS application are slower than other client server applications. In order to gain the required service speed the companies need to implement a much better computing environment to run the application properly. Requirement for connectivity: Without the help of the internet connection the users cannot utilize the SaaS application (Grozev Buyya, 2014). If the speeds of the internet services are found to be slower then, the application would also become slower and thus the users will not be able to access the software and data easily. The SaaS that could be recommended The name of the service Many SaaS service providers are there and based on the type of the businesses the owners do select the most supportive and beneficial service providers for their company. After analyzing the components and service features of Webb Store, it is found that NetSuite is the most effective Software as a Service (SaaS) provider. The wide ranged business application can be fluently served by the service providers (Zhao, Li Liu, 2014). Apart from the general services it also provides completely featured accounting and financial characteristic, Customer Relationship Management (CRM), E-Commerce software and inventory to the consumers. Moreover, it can be said that, NetSuit is able to provide an integrated service to Webb Store. How it is better than other similar services Financialforce is another SaaS software service provider that possesses the CRM features as well. However, considering the number of staffs and their ability to run the system application properly, it are determined that NetSuite s one of the most beneficial software service provider (Jain Mahajan, 2017). The company will be able to get commercial benefit from the competitive market after the adoption of this software vendor. Email marketing is not required for this particular company thus; they should adopt the NetSuite over Financialforce. The software application could run properly with lesser time and cost as well. Even the marketing ROI also increases after the implementation of SaaS service as their business application platform. The specific disadvantages Though the service provides high range benefit to the users but still the most highlighted issue associated to this is the variable functionality and features. The hosted applications are completely limited to serve the desired software functionality however, due to lack of some of the application level features and functionalities, the application become limited (Furuncu Sogukpinar, 2015). Additionally, the critical business solution cannot be served with the help of this service. An IaaS approach to migrate Webb stores database to the cloud The Webb Store has three data centre in Sydney, Melbourne and Brisbane and the company uses 2012 R2 database for managing their confidential data. However, the company is facing data management challenges for using this application and thus in order to mitigate these challenges the company is willing to migrate their platform from the general to IaaS based cloud (Selvam Kannan, 2015). The IaaS platform has enough flexibility and scalability thus for gaining on premise and on demand scalability, Webb store is migrating their service platform. A PaaS approach to migrate Webb stores database to cloud The PaaS cloud platform is very much cost reduced and compared to other service providers, the companies those are using the PaaS cloud platform are able to save more than 50% of operational savings to the owners. The technology stacks could be managed by the project teams properly (Manuel, 2015). The capital expenditure could be minimized with the help of some of the database elements like server, storage, network components etc. Even the operational expenditure also gets reduce with the help of these elements. Advantages and disadvantages of the approaches Factors Advantages Disadvantages Flexibility Due to the presence of extreme level flexibility, the operation capabilities of the systems get increased and the overall investment cost also gets reduced with this approach. System flexibility is beneficial but at the same time extreme flexibility, interrupts the security of the system. System complexity If the system is found to be complex, then the security of the system get enhanced and due to this none of the external users will be able to access the server without proper authentication (Alhamazani et al., 2015). If the system is found to be complex enough then the employees will not be utilize the application properly. Then, in order to utilize the platform properly, training and development program is required to be arranged by the management authority of the company. Set of recommendations to mitigate the issues of cloud computing Encryption: With the help of proper encryption the server and the information transmission channel will be secured from the external attackers. Authentication: With authentication none of the unauthorized users will be able to access data from the server. References Abdelmaboud, A., Jawawi, D. N., Ghani, I., Elsafi, A., Kitchenham, B.
