    Implementation of the integration of the UnB service bus with monitoring tools

    Master's Thesis in Applied Computing, University of Brasília (Brazil)

    2020
    Advisor(s)
    The adoption of a Service-Oriented Architecture (SOA) in the implementation of services and microservices in distributed system applications facilitates the use of development standards, maintenance, flexibility in service development, and interoperability between services and systems. The Computing Center (CPD) of the University of Brasília (UnB) engages in various software automation processes, ranging from the maintenance of existing systems to the development and deployment of new technological solutions. Continuous monitoring of the performance of services, microservices, and systems becomes crucial. This study, of an exploratory nature, aims to investigate solutions and tools for implementing and managing the monitoring of distributed services and systems at UnB, through systematic mapping. The research was theoretically grounded to develop a model that was applied to the monitoring module of the UnB service bus. Simulations were conducted with the developed solution, allowing the analysis of the integration between the service bus and the proposed monitoring tool.

    Service-Oriented Architecture (SOA), Agile Development Methods and Quality Assurance (QA) - a case study

    Master's Thesis in Applied Computing, University of Brasília (Brazil)

    2019
    Advisor(s)
    This work introduces the NatVI framework, focusing on the integration between Service-Oriented Architecture (SOA), Agile Development, and Quality Assurance (QA). Developed from a literature review that identified and evaluated the trade-offs between SOA and agile methods, NatVI aims to provide a comprehensive solution for the software development cycle, especially for service-based applications. It includes best practices from SOA and agile principles, emphasizing the importance of QA, essential for software projects in dynamic business environments. A case study in a unit of the Brazilian federal government assessed the application of NatVI, observing improvements in software quality, understanding of agile methods, and client satisfaction with the development process. The study also highlighted limitations, such as the size of the IT team and the number of clients involved, leading to a subjective evaluation through semi-structured interviews. The preliminary results suggest that NatVI has potential, but also highlight the need for further research, paving the way for future studies on emerging technologies, such as containers and DevOps.
