The document discusses spatial data infrastructures (SDIs) and the potential advantages and disadvantages of using cloud computing for SDIs. Some key points: - An SDI is a framework of spatial data, metadata, users and tools that allow for efficient and flexible use of spatial data. - Cloud computing provides on-demand access to configurable computing resources over a network. There are different service and deployment models. - Potential advantages of cloud computing for SDIs include scalability, pay-as-you-go costs, and not needing dedicated servers. However, organizations need to keep control of important components and ensure security and privacy. - Switzerland's Federal Office of Topography uses an infrastructure
