If you are interested in hands-on materials to get familiar with ArcGIS Utility Network, here are some excellent resources:
- Learn ArcGIS Utility Network for Electric Utilities
- Learn ArcGIS Utility Network for Gas and Pipeline
- Learn ArcGIS Utility Network for Water Utilities
- Getting started with the ArcGIS Utility Network series (other)
Each of these provide industry-specific solutions, tutorials, articles, and resources for further learning in an interactive learning format.
Likewise, if you are interested in best practices for implementing and deploying ArcGIS Enterprise, including reference system and architecture diagrams, make sure you check out the ArcGIS Architecture Center and the following blog which will help you navigate it Architecture Practice Resource Page (esri.com).
Find resources about System Patterns such as:
- Introduction to Architecture practices
- Data editing and management system
- Enterprise application hosting and management
- Mobile operations and offline data management system
Also, learn about Architecture Practices and the six architecture pillars of the Well-Architected Framework: automation, integration, observability, performance and scalability, reliability, and security.
I also highly recommend that you check out Architecting the ArcGIS System PDF (esri.com)
