ArcGIS Pro is the newer alternative interface to the tried-and-true ArcGIS Desktop software (ArcMap), with essentially the same functions, but with more of a MS-Office feel. As a native 64-bit program, it also has superior performance. There are a few nice feature enhancements such as multiple layouts in a single project, and it's more fully integrated with ArcGIS Online (see schedule for workshops on ArcGIS Online or on StoryMaps).
