Overview
ArcGIS for Server is the enterprise component of the ArcGIS Platform. It provides you with a complete Web GIS that runs behind your firewall, on your infrastructure, and dovetails with your enterprise systems and policies.

ArcGIS for Server software gives you the ability to create, manage, and distribute GIS services over the Web to support desktop, mobile and Web mapping applications.

To create GIS services, you use ArcGIS for Desktop to author geographic content, such as maps and GIS tools, and then publish that content using ArcGIS for Server so that it can be used anywhere in your enterprise and on the Web.

ArcGIS for Server simplifies access to GIS services for GIS professionals, mobile workers, as well as knowledge workers without any GIS experience. With ArcGIS for Server, you stay in control of your content through centralized management of spatial data, including imagery.

In addition, ArcGIS for Server provides you with a scalable GIS server platform that can be deployed on a single machine to support small workgroups, or it can distributed across multiple servers for supporting enterprise applications. You can also deploy ArcGIS for Server on Cloud infrastructure.

Key Features
ArcGIS for Server provides you with a full range of GIS server capabilities that allow you to transform the maps, imagery, data, and GIS tools that you commonly use in ArcGIS for Desktop into fast, reliable Web services that you can use anywhere. You can use these services to support a wide variety of mapping applications, either on the Web or your local network.

You can choose from Basic, Standard, or Advanced editions of ArcGIS for Server:
