In this presentation, we will dive into how EO4EU's Observability Platform, a suite of community projects, is tasked to observe the multi-cloud infrastructure spanning two distinct OpenStack clouds, WEkEO DIAS and CINECA ADA Cloud, and multiple Kubernetes clusters distributed across them.

Cross-cluster configuration management and replicability are ensured by the implementation of Infrastructure as Code (IaC) and GitOps best practices. By embracing a logical framework of "observer" and "observee" cluster annotations, every cluster provisioned within the platform is automatically configured to transmit metrics, logs, and tracing data to a central "observer" cluster. Simultaneously, each cluster retains data locally for a specified retention period, ensuring local data availability.

Join us to learn more about our journey! We will offer a comprehensive view of our setup, illustrating how open-source tools can come together to provide insights into your applications.
