Is ArcGIS Server a Web Server?


Angela Bailey

ArcGIS Server is a powerful tool used in the field of Geographic Information Systems (GIS). It serves as a platform for creating, managing, and sharing GIS resources such as maps, data, and services. However, it is important to note that ArcGIS Server is not a web server in the traditional sense.

What is a Web Server?
A web server is a software or hardware system that hosts websites and delivers web content to clients over the internet. It listens for incoming requests and responds by serving static or dynamic content. Web servers commonly use protocols such as HTTP or HTTPS to communicate with clients.

What does ArcGIS Server do?
ArcGIS Server, on the other hand, is designed specifically for GIS functionality. It provides a framework for publishing and managing GIS services that can be accessed over the web. These services include map services, geoprocessing services, image services, and more.

Map Services:
Map services are one of the key features of ArcGIS Server. They allow users to access and interact with maps over the internet.

Map services can be created from various data sources such as shapefiles, geodatabases, or remote sensing imagery. These services can be consumed by applications or accessed directly through web browsers.

Geoprocessing Services:
ArcGIS Server also supports geoprocessing services. Geoprocessing involves performing spatial analysis and modeling tasks on GIS data. With geoprocessing services, users can execute complex spatial operations remotely without having to install specialized GIS software on their local machines.

Image Services:
Image services enable users to work with large collections of imagery data over the web. This includes displaying images in different formats (such as JPEG or TIFF), performing image analysis tasks like classification or change detection, and sharing those results with others.

ArcGIS Server provides robust security mechanisms that allow administrators to control access to their GIS resources. It supports user authentication and authorization, ensuring that only authorized individuals can view or modify the data.

How does ArcGIS Server work with web servers?

While ArcGIS Server is not a web server itself, it can work in tandem with popular web servers such as Apache HTTP Server or Microsoft Internet Information Services (IIS). These web servers act as intermediaries between clients and ArcGIS Server, handling client requests and forwarding them to the appropriate GIS services.

ArcGIS Server leverages the capabilities of web servers to provide additional functionalities, such as load balancing and caching. Load balancing helps distribute incoming requests across multiple instances of ArcGIS Server, ensuring efficient use of system resources. Caching allows frequently accessed map or image data to be stored locally on the web server, reducing response times for subsequent requests.


In conclusion, ArcGIS Server is not a web server itself but rather a specialized GIS platform for creating and sharing GIS resources over the internet. While it requires a separate web server to handle client requests, ArcGIS Server integrates seamlessly with these web servers to provide powerful GIS functionality. By leveraging the strengths of both systems, organizations can build robust and scalable GIS applications that meet their specific needs.
