Migplan: processo aplicado na rentabilidade empresarial através de reengenharia de sistemas

Abstract

Legacy systems suffer from several problems in current production scenarios. For example, the high cost of server maintenance and the need for growth in the market. Strategies to reengineer and modernize these systems are necessary. The objective of this work was to create a process to improve the profitability of companies that use legacy systems through the reengineering of the architecture of these systems. To achieve this goal, the process defined a new architecture that uses concepts of cloud computing. This new architecture provides the use of a new data transmission stream that enables operability in a contingency in case of errors or server shutdown. To validate the process, a case study was proposed, with the goal to perform the migration of a legacy functionality for modern functionality through approaches and techniques. The approaches structured how the migration should occur, aiming at agility, security, and performance. The techniques were used to extract the knowledge necessary to carry out the migration and put all approaches into practice. As a result, in this work, we concluded that the process reduced the cost of downtime for the business end user.
