Integration & APIs
Standardized Interfaces for
Intelligent Inventory
Open Digital Architecture (ODA) aligned APIs, real-time event streaming pipelines, and secure data contracts. Built to seamlessly integrate the Inventory Intelligence Agent into legacy OSS landscapes.
TM Forum Open API Compliance
Azalio's Inventory Intelligence Agent speaks the language of modern OSS. By implementing certified ODA components and standard TMF APIs, we eliminate proprietary integration debt.

Strangler Pattern Migration Strategy
Replacing a legacy inventory monolith introduces immense operational risk. Azalio employs the Strangler Fig pattern to systematically decouple dependencies, routing API traffic intelligently and deprecating legacy systems domain-by-domain without downtime.
1
Introduce API Gateway Facade
All northbound systems route requests to the new API Gateway, which initially proxies 100% of traffic to the legacy monolithic inventory.
2
Stand up Inventory Intelligence Agent
The Agent begins ingesting state changes from legacy inventory and network elements in parallel, populating the Neo4j graph without interfering with active read paths.
3
Traffic Routing & Cutover
The Gateway routing logic is updated to direct specific queries (e.g., TMF638 Service lookups) to the new Agent, while legacy handles the rest.
4
Deprecate Legacy Modules
As confidence builds, more domains are migrated until the legacy inventory can be safely decommissioned.
