As we conclude the EU-funded ACCORDION Project, we cordially present the final edition of our newsletter, focusing on sharing the latest blog articles and webinars organized by our consortium.

Over the duration of the ACCORDION project, our dedicated experts, researchers, and organizations have made significant strides in advancing Multi-Cloud and Edge Computing, and we are grateful for the unwavering support of the European Union in helping us realize our goals. This final newsletter will offer insights into our project's latest discussions and discoveries, emphasizing the value of our collective expertise in shaping the future of Edge Computing. We invite you to explore these valuable resources by visiting our project website.

As we bid adieu to this project, we express our heartfelt gratitude to all who have been part of this remarkable journey and look forward to the opportunities that lie ahead in fostering a more connected and efficient future.

The ACCORDION project develops a framework allowing to share and federate infrastructure resources on the edge, so allowing to the deployment of high-demanding applications where the best user experience can be achieved. This webinar presents ideas for a suitable business model to apply at such federations, discussing among others alternative governance models and related technical implications.

Multi-cluster and multi-cloud topologies are becoming increasingly common in Kubernetes, with the consequent necessity to orchestrate a large number of clusters (e.g., at the edge). This talk presents the Liqo.io open-source project (700+ stars on GitHub), which aims at offering an open-source technology to build and orchestrate multi-cluster and multi-cloud topologies. The talk briefly introduces the multi-cluster/multi-cloud problem, the main technical pillars behind Liqo, and a live demo of the system. Finally, the talk highlights some of the future directions, including the possible adoption of Liqo in the StucturaX/Gaia-X initiatives, and how this project could become a key ingredient to achieving European sovereignty in cloud computing technologies.

Computing Continuum management is a fast-growing field of techniques and tools, aiming at the joint exploitation of Cloud and Edge infrastructures together to fulfill requirements from a variety of applications. In this seminar we propose the different takes at Continuum exploitation of two H2020 projects, ACCORDION and CHARITY. Both projects aim at leveraging information about the application structure and its needs (in terms of resources, constraints, QoS targets, and QoE ones) to dynamically match the available resources at all levels of the Continuum platform. Information continuously gathered from the platform allows to plan and steer distributed applications and their allocation tradeoffs in near real time to satisfy the user expectations. Edge exploitation for services is a powerful tool to spread computation load and reduce service latency, but requires utter care in enabling local acceleration and managing more constrained resources. We introduce the viewpoint, main goals, design choices and current results of both projects. ACCORDION looks for a generic support to multiple application structures and application fields, where the formalisation of the application constraints and goals is essential to exploit the information dynamically made available from all parts of the platform.  By comparison, CHARITY looks at the needs of AR, VR and Holographic applications. The problem viewpoint thus shifts toward a class of applications that place quite daunting constraints on the allocated resources, mandating the use of more sophisticated and targeted allocation and co-scheduling techniques to closely deal with complex network, storage and computing requirements, while also satisfying application-specific needs like Edge-based 3D rendering acceleration and caching.
