ArcGIS for Server is software that makes your geographic information available to others in your organization and optionally anyone with an Internet connection. This is accomplished through web services, which allow a powerful server computer to receive and process requests for information sent by other devices. ArcGIS for Server opens your GIS to tablets, smartphones, laptops, desktop workstations, and any other devices that can connect to web services.
To get started with ArcGIS for Server, you’ll need to prepare your hardware, software, and data, then you can set up GIS web services. Finally, you can use various types of applications to consume your services.
