Description: Decide early on the type of deployment: On-premise, vs. Cloud-native and sourcing models IaaS, PaaS, SaaS, etc Additional information: It is relevant for the success of Digital Public Services to select the deployment methodologies that fit the needs of the administration and stakeholders (citizens and businesses). European Commission cloud strategy: "Cloud-first with a secure hybrid multi-cloud service offering". Cloud-first means that systems should rather be conceived in such a way that they can benefit from the advantages of cloud based delivery models, which exist both on premise and in the public cloud. The choice of architecture, especially of on premise and/or public cloud, will depend on the advantages, constraints and risks for a specific system. So it does not mean that all systems should go to the public cloud.
