The use of hybrid deployment models is becoming a standard since it provides many benefits regarding on-demand scalability, high availability, and reliability. However, the management of resources (application specifications and infrastructure details) in a hybrid environment is a complex task since interfaces vary depending on the ven dor. Therefore, continuous practices already established must be adjusted whenever new interfaces are to be supported. This work aims to explore how a deployment process can be improved regarding the adoption of hybrid environments at the host organization DevScope, producing a proof of concept capable of explaining how this improvement can be achieved. A Components-of-the-Shelf (COTS) approach is followed for developing the solution that relies on different technologies to achieve the expected results. The proof of concept consists of deploying the infrastructure that supports the new deployment process and the orchestration of the components to enable the delivery of applica tions to the environments. Terraform is used to define and deploy the infrastructure, and KubeVela is the technology used for managing applications. The implementation of the solution made it clear that managing applications in heterogeneous platforms is not easy. After some experimentation and answers to a prepared questionnaire regarding the new deployment process, it was possible to conclude that the solution still has a margin for improvement and that some technologies are projects still being actively improved. Although KubeVela is not polished enough, it was possible to verify that it is easily extendable and that more scenarios for specific applications can be added when needed. The obtained results are relevant for future studies and will contribute to a better understanding of how the delivery of multiple applications can be homogenized. It also helps to address other problems, such as oversimplification of deployments, losing important infrastructure-based details, and the associated learning curve to deploy a complex application.
