Digital twins are virtual representations of physical entities. They are an emerging technology gaining increasing importance in several domains thanks to their ability to simulate and understand their physical counterpart, consequently improving decision-making processes. Digital Twin as a Service is a software platform developed by the INTO-CPS Association at Aarhus University, which provides the ability to build, use, and share digital twins with other users. The work presented in this thesis was carried out in collaboration with Aarhus University. Its main objective was to design and implement a DevOps framework for managing digital twins lifecycles, integrating GitLab APIs and CI/CD pipelines.
