The document discusses strategies for sharing valuable data that is currently locked inside systems by using cloud services. It suggests that cloud services can help with discovery of data, promoting use of collections, enabling data mining and visualizations, combining data with other sets, and allowing global access. However, the document cautions that the appropriate cloud service and data format depends on what you want to do with the data, such as storage, collaboration, or combining datasets. The document provides questions to consider when choosing a cloud service, such as why you want to share data, what format it is in, sustainability of the service, and licensing of shared data.
