This document discusses implementing continuous delivery for a cloud gaming service. It proposes using Scrum and designing a development pipeline to maximize productivity. The project aims to apply a methodology to a multidisciplinary team, integrate proprietary and open source systems, and develop a product to serve users. The pipeline would deploy new versions and configurations to the cloud automatically. It was validated using monitoring tools and testing methodology. Improvements could include making upgrades nondisruptive and extending orchestration to other clouds. Overall the objectives of adopting Scrum and continuous delivery were achieved.
