Explore the implementation of ephemeral clusters as a service using ClusterAPI and GitOps in this 29-minute conference talk by Alessandro Vozza from Solo.io and Joaquin Rodriguez from Microsoft. Learn how to address the challenges of managing multiple Kubernetes clusters across different cloud providers at scale. Discover how open-source tools like ClusterAPI, ArgoCD, and Prometheus+Thanos can help tame the complexity of scaled infrastructure, providing control and visibility over numerous clusters. Gain insights into automating the deployment of hundreds of clusters and applications securely, while collecting metrics from ephemeral clusters. Understand the advantages of GitOps over traditional CI/CD tools and how to overcome the growing pains of scale, particularly in observability and security aspects.
