The diploma thesis describes the development practices of continuous integration, delivery and deployment, which together make up the CI/CD pipeline. Their main task is to ensure the quality of software by automating repeatable processes. Within the diploma thesis, three tools are presented that enable the implementation of the CI/CD pipeline: Jenkins, GitLab and Travis CI. All the mentioned tools were tested in the Amazon cloud, where we set up a CI/CD pipeline, for the purpose of analysis. The main goal of the diploma thesis was to identify the properties of CI/CD tools and the criteria by which we defined the evaluation model. Properties and criteria were obtained by reviewing the literature. The result of the diploma thesis is a model of CI/CD tool evaluation, which was used in a specific case in cooperation with the company and offers decision support.
