Abstract(s)
The concept of Cloud Computing has evolved constantly, in strand of service models, based on the creation and share of several technological resources. Increasingly, it has used virtualization technology to optimize resources, which are shared by all accounts, in a self-service format. All these features result in a flexible and progressive behavior of resources. The management of the service provided, is made based on the service level agreement established between the client and the cloud provider, and the constant technological developments can quickly change depending of the requirements. That said, knowing the current state of Wipro with respect to the concepts of data migration and cloud being combined into one, it is very challenging to design and build a possible process to help the company make this transition. Especially, when there is already a tool that has been used for several years and it is intended to be part of this integration with a new possible solution that is described along this document. The study, of qualitative nature, is guided by different case studies when it comes to the processes being used to migrate data into Cloud. The main objectives are to find new solutions that increase productivity of the company, save human resources that can be reallocated to other tasks, ending up to be considered innovative solutions, with rapid implementations and most importantly with low cost. What ends up in the overall objective of this dissertation that is to examine the feasibility of the adoption of Cloud Computing in Wipro Portugal through two main points: • The migration of data into Cloud; • Integration with Data Conversion Tool (DCT). We believe that this approach is very meaningful towards encouraging greater productivity and obtaining new achievements. Concerning the empirical study, there is a big number of tools that can be investigated later as possible solutions for other kind of implementations than Oracle Retail. For now this dissertation focus in the current OR business approaches and points for Oracle Cloud as the main Cloud Computing Service due to its partnership with Wipro. Both solutions that were implemented, SQL Loader and Golden Gate, seem viable and versatile as they can be integrated with the current tool, DCT and are capable of loading several amounts of data without any issues. In terms of performance Golden Gate seems to be a few steps above of SQL Loader, but requires deeper analysis when using multi threading as an option in both methods, and the containerization of the databases can be very relevant regarding the times of loading. In general, good solutions are available and need to be taken into consideration by the company as they can help to leverage its resources in a more efficient way and the main objective of having data in the Cloud was reached, having gathered knowledge about the behaviour of Oracle Cloud and some of the services.
