RT Journal Article T1 ACSmI: a solution to address the challenges of cloud services federation and monitoring towards the cloud continuum A1 Alonso, Juncal A1 Huarte, Maider A1 Arrieta, Leire Orue Echevarria AB The evolution of cloud computing has changed the way in which cloud service providers offer their services and how cloud customers consume them, moving towards the use of multiple cloud services, in what it is called multi-cloud. Multi-cloud is gaining interest by the expansion of IoT, edge and the cloud continuum where distributed cloud federation models are necessary for effective application deployment and operation. This work presents advanced cloud service meta-intermediator (ACSmI), a solution that implements a cloud federation, supporting the seamless brokerage of cloud services. Technical details addressing the discovered shortcomings are presented, including a proof of concept built on JHipster, Java, InfluxDB, Telegraf and Grafana. ACSmI contributes to relevant elements of the European Gaia-X initiative, specifically to the federated catalogue, continuous monitoring, and certification of services. The experiments show that proposed solution effectively saves up to 75% of the DevOps teams’ effort to discover, contract and monitor cloud services.
