Ubiquity repositories, which are based on Hyku, are designed to be highly scalable, highly reliable and quick to deploy in the cloud. In this presentation we will outline the technical architecture we have implemented, along with the challenges faced. These include scalability, security, cost-efficiency, performance, reliability, resilience, portability, delivery pipelines for code deployment, error reporting, testing and localization. We will also discuss our approach ensuring we remain on the most recent stable branch of the platform and contributing our code back to the community.
