I am trying to develop a GIS web application. I am using ArcGIS for desktop as the database. I need to use existing ArcGIS Restful services but also need to publish some new services. I think that ArcGIS for server would be the best choice for me. But I cannot afford it. And I want to know:
- If there is a free lightweight version of ArcGIS for server?
- Does a open source alternative such as GeoServer have APIs to use ArcGIS Restful services?
