The goal of the E2CC project is to develop a standardized, end-to-end platform for supporting edge-cloud applications. It aims to guarantee interoperability, portability, infrastructure management, and orchestration while integrating decarbonization, AI/MLOps, and cybersecurity. E2CC is one of 19 IPCEI-CIS projects (Important Project of Common European Interest on Next-Generation Cloud Infrastructures and Services). It contributes to several open-source projects, including ALUMET and MojitO/S, which monitor energy consumption to help optimizing decarbonation.
