Over the last years, new architecture arose with the aim of easing the deployment and the usage of geospatial data and software in the cloud. Large accounts are starting to leverage the power of Kubernetes in public clouds such as AWS or Azure associated with traditional OSGEO software such as GeoNetwork and GeoServer. In this talk we'll present our experience and results of working with large institutions in the public sector (civil defence, judiciary) or in the private sector (insurances, telecoms). We'll demonstrate how working the agile way with open-source software and high-level contributors allow to tackle successfully even the most ambitious challenge. As a result of these efforts (multiple 100-man days contributed to the communities), we could participate significantly in developing GeoServer cloud as well as GeoNetwork microservice. Both projects aim to solve the cloud native challenge and are well underway of succeeding. After such an initial effort, we encourage every party using open-source software to participate in the maintenance and contribute to open-source development. Only with a real open-source engagement can we as a community achieve producing sustainable best of breed open-source software. Finally, we recommend customers to make sure their service providers have a positive impact in the communities.
