Open Digital Architecture (ODA) Canvas for Telco Operations Transformation

The Open Digital Architecture (ODA) Canvas represents a significant milestone in telecommunications industry transformation, spearheaded by TM Forum to create a standardized blueprint for digital service providers. This comprehensive framework aims to replace traditional monolithic BSS/OSS systems with cloud-native, component-based architecture that enables rapid innovation and operational efficiency.Please note that the project is evolving as we speak. Thus, all technical specifications and implementations should be verified against the latest TM Forum documentation, as the ODA Canvas is continuously evolving based on industry feedback and technological advancements.

Technical Foundation and Core Principles

The ODA Canvas is built upon several key technical principles:

1. Cloud-Native Architecture

• Implements cloud-native design patterns using containerization and microservices
• Leverages Kubernetes for orchestration and deployment
• Employs service mesh architecture for inter-service communication
• Utilizes API-first approach with OpenAPI specifications

2. Component-Based Design Structure

• Core Commerce Management (Product Catalog, Order Management, Revenue Management)
• Engagement Management (Customer Management, Party Management, Channel Management)
• Production (Resource Management, Service Management, Infrastructure Management)
• Intelligence Management (Data Analytics, AI/ML Operations, Decision Support)

Implementation Reference Architecture

The ODA Canvas implements several crucial architectural layers:

1. Engagement Layer
