Datalab, the La Silla Paranal Observatory Platform for data analysis, is being migrated from Docker Swarm to Kubernetes to align with the integrated operations program's goals: Remote, Lean, Sustainable, and High performance. The migration implied to move from an on-premises to a cloud-native infrastructure replicated locally into a Cloud-Edge, providing hybrid cloud containerized applications support, implementing DevOps practices and automation. Using infrastructure as code and configuration management tools like Terraform and Ansible. Building CI/CD pipelines in Gitlab to automatically deploy the proper infrastructure into to the hybrid cloud to hold Kubernetes clusters (Azure Kubernetes Cluster and Vanilla Kubernetes). This approach allows the Observatory to enhance efficiency, reducing power consumption and improving scalability. Using Datalab as proof of concept but setting up the foundation to standardize these technologies in the organization. This paper outlines the provisioning and deployment of the new hybrid cloud infrastructure, providing a concise overview of its architecture, operational impact, and benefits for the observatory.
