Pros and Cons of IaaS and PaaS-Samples for Students-Myassignment

Question: Discuss about the IaaS and PaaS approach of moving the Database of Webbs Stores to the Cloud. Answer: Introduction Cloud Computing is an internet based process of computing that will allow sharing of resources, computing and storing information online. This allows an organization to perform certain functions without investing or purchasing their own resources. This report discusses about the IaaS and PaaS approach of moving the database of Webbs Stores to the cloud. This report compares these two approaches and suggests a suitable approach for Webbs Stores. IaaS approach of moving the database to the Cloud Infrastructure as a service is a service model of the Cloud Computing that will allow Webbs Stores to access network, storage facilities and also storage services (Jadeja Modi, 2012). It will also provide administration and hardware services. The Webbs Stores needs to build an application and load all its software that will run in the cloud. Then they need to upload the VM to hosts environment. IaaS approach is best when the organization has no time for reengineering the application. The company needs to take into account a technology domain. Certain conditions like checking the financial considerations must be satisfied without which migrating to IaaS will become difficult (Rittinghouse Ransome, 2016). This approach has certain disadvantages like dependence on third party and degradation of service quality. In IaaS, the Webbs Stores will have full privilege in accessing the virtual machine. Few things that are needed in order to migrate the database to cloud are data stream amount and resource requirement that are dynamic. This approach migration is different than migrating via PaaS approach. PaaS approach of moving the database to the Cloud Platform as a service is a Cloud service model that provides a platform for developing applications over the internet by providing hardware and software like middleware and software (Wang et al., 2012). Webbs Stores will be provided with all the facilities for developing and delivering the software that will help them to build cloud applications and release them in an elastic and scalable environment. Steps to be taken by Webbs Stores to move the database to Cloud by PaaS approach are configuring an Azure SQL Database and Azure Web App. The company never has to log in to the VM server (Gibson et al., 2012). The PaaS approach has several restrictions at every layer of technology of the stack of application like database, programming language, third party library, middleware and restrictions associated with the selected PaaS. Advantages and Disadvantages of IaaS and PaaS approach IaaS Approach PaaS Approach Advantages: The workload required for this approach is little. The complexity of the migration process is very easy. It has no complexity as such. There is no need for adaptation (Kavis, 2014). This approach saves the expenditure of capital that is required for hardware. Advantages: This approach offers a scalability that is dynamic in nature. The configurable procedure is easy. It has the lowest cost among all the cloud approaches. Availability is high. Disadvantages: This is the most expensive approach among all the approaches. Customer has to take the responsibility of managing the virtual machine. Customer is responsible for the backups. The customers do not have control over the server or physical location of the virtual machine. Disadvantages: The migration workload is moderate as compared to IaaS. The complexity of migration is also moderate. The customer needs to modify application to make it compatible with PaaS (Garrison, Kim Wakefield, 2012). Platform is shared among multiple customers. Table 1: Benefits and Challenges of IaaS and PaaS Approach Recommendations The Webbs Stores should take the PaaS approach as this will provide the company with a platform to develop its own application along with storage and resource sharing facilities. It is scalable and easy to configure. The cost of this approach is the lowest. This is not a time consuming process. Conclusion This report concludes that the best option for Webbs Stores is to take the PaaS approach to move its database to the cloud because this is the suitable for the purpose of this company.
