The Modular Myth: Why OSS Architecture Must Be Built Around a Digital Twin
For years, telecom architecture has been guided by a simple belief: If we make it modular, we make it flexible. Operators split the OSS stack into components, separated domains, and connected everything through APIs. On paper, it works. In reality, it created the very complexity operators are now trying to escape. Because what the industry calls “modular” isn’t true modularity, it’s fragmentation with interfaces. And that distinction matters. The Illusion of Modular OSS Traditional OSS stacks evolved as independent layers: Inventory Configuration management Fault management Orchestration Assurance Each system operated independently with its own data model and timeline. But together, they never aligned. This structure may have enabled modular evolution, but at a cost. No system ever had a complete, real-time understanding of the entire network. Instead, operators had to rely on synchronization, correlation, and reconciliation – All after the fact. This diconnect has resulted in a number...
