Logical architecture

This logical view of the reference architecture defines individual software components, how they are separated or combined together, and key interactions between them.

Logical reference architecture for a Network Management System


This reference architecture was designed with a focus on specific workflows and capabilities.

Software components

This diagram contains a variety of software components that contribute to the overall system design, including:

Key interactions

The software components described above interact with each other in the following ways:

  • Client applications communicate with enterprise data services over HTTPS, typically via stateless REST APIs. A friendly, well-defined domain name is recommended as the entrypoint to the system. Three separate ArcGIS Web Adaptor instances configured in the web server handle context path based routing to the Portal for ArcGIS and ArcGIS Server components described above. Learn more about DNS, naming, and URLs.
  • Client applications communicate with basemaps and location services provided by ArcGIS Online over HTTPS, typically via stateless REST APIs. This requires connectivity from client machines to the internet.
  • ArcGIS Server maintains persistent TCP connections to both the database management system (DBMS) hosting the enterprise geodatabase as well as the ArcGIS Data Store. The former requires that appropriate database client software be installed on the ArcGIS Server machines communicating with the DBMS.
  • ArcGIS Pro communicates with the ArcGIS License Manager using TCP/IP protocols. Learn more about configuring ArcGIS License Manager with ArcGIS Enterprise Portal and configuring ArcGIS License Manager to work through a firewall.
  • ArcGIS Monitor communicates with a variety of ArcGIS and IT (e.g., DBMS) components using a variety of mechanisms. See ArcGIS Monitor documentation for more information.
  • References to location services hosted and managed by ArcGIS Online are typically registered and made available for use within ArcGIS Enterprise. See configuring ArcGIS Online utility services, configuring ArcGIS Living Atlas content, and distributed collaboration.

Additional information on interactions between ArcGIS Enterprise components can be found in the ArcGIS Enterprise on Windows and Linux product documentation, including a diagram of ports used in an ArcGIS Enterprise on Windows and Linux deployment.
