Arc2Earth Cloud allows users to publish geospatial data and maps to ArcGIS.com inexpensively without requiring expensive server infrastructure. It uses Google AppEngine for scalable and inexpensive hosting, the ArcGIS REST API to integrate with ArcGIS Online, and can export map tiles and vector data from ArcMap desktop. While it is lightweight and scalable, it is limited to static map tiles without geoprocessing capabilities. It is well suited for small groups to share and edit geospatial data through a browser.
