Architecture
The Cloud Native Unified Data Repository architecture has following three tiers:
Connectivity Tier
- 5GNF API Gateway (using Spring Cloud Gateway) receives all requests and forwards them to the Nudr-drservice service of Business Tier.
- It uses Oracle MySQL Cluster CGE database technology for backend database in the DB tier, which provides HA and geo-redundcancy capabilities.
- It load balances the traffic and provides required authentication.
- It runs on Kubernetes as a microservice.
Business Tier
- Provides the business logic of 5G Unified Data Repository.
- It runs on Kubernetes and
has following three micro services:
- nudr-drservice: The core service which will handles flexible URI support, runtime schema validation and connects to Data Tier for DB operations.
- nudr-nrf-client-service: Handles registration, heartbeat, update and deregistration with Network Repository Function (NRF).
- nudr-notify-service: Handles notification messages to Policy Control Function (PCF) for data subscriptions.
Data Tier
- Uses Oracle MySQL Cluster CGE database technology for backend database in the DB tier, which provides HA and geo-redundcancy capabilities.
