ArcGIS technologies are well known and are widely used. Even though applications built using these technologies help decision makers in government sectors, not many of these organizations could afford the cost incurred in holding a license for ArcGIS Server (which also makes it mandatory for buyers to hold a license for ArcGIS desktop as well, because without it publishing layer on the server is not possible). The licensing and cost of software packages of ESRI are very complex and vary depending upon the functionality an organization requires. Opting for ESRI technologies incurs heavy costs for any organization irrespective of whether it is a government or private.
