Project Description:
The "Architecture & Design / Proof-of-Concept (PoC)" project is a key component of the overarching "Central Services Program".
Its primary focus lies in supporting the services for Asset Management, specifically related to the business asset “Substation”. In the future, the solution may be extended to include additional decentralized environments.
The objective of Asset Management is to enhance business processes for substations by enabling remote management capabilities, thereby increasing efficiency and operational flexibility.
Within the scope of the Solution Design Implementation – Proof-of-Concept project, a functional PoC environment will be designed, developed, and implemented to demonstrate the feasibility of Remote IT Services for managing secondary technology at substations.
This includes both hardware and software components, in alignment with Asset Management requirements. Additionally, the project covers the installation of the designed environment and services, forming the
foundation for subsequent phases.

The Central Services covered by the PoC include:
• User Management (IAM) based on Microsoft Active Directory
• Patching and Software Distribution
• Logging and Monitoring
• Time Synchronization Protocol
• Backup and Restore

This Proof-of-Concept will validate the architectural approach and serve as a reference for future scaling and operational integration.

- Requirements Gathering and Analysis
- Design of the Compute Environment for Central Services
- Design of the Active Directory (AD) Solution
- Design of the Compute PoC Solution
