Design
Design Principles
- Reusable Components
POMBA is developed based on microservices-based architecture to ensure pluggable capability into other Data Integrity sub-system
POMBA uses other microservices initially designed for A&AI component promoting them as a platform modules.
- Event-Driven
POMBA is event-driven application to ensure auditing without affecting existing systems.
- Extensibility
POMBA is implemented based on Context Builders Framework to ensure that core audit process is decoupled from the target system integration specifics.

Process Flow
Sub-Components
POMBA leverages context builders approach to provide pluggable framework of accessing various ONAP components to retrieve the data.
It allows to encapsulate the complexity of reaching a component as well as implement the mapping and transformation component’s related data to common model consumed by audit process.
SDC Context Builder
The purpose of SDC Context Builder is to encapsulate the complexity of interaction with SDC component .

SDN-C Context Builder
SDN-C Context Builder is aimed to encapsulate the functionality of accessing SDN-C via RESTful APIs and transform the data into common model structure used by audit process.

Validation Service
Validation service is a core microservice which implements rule processing engine.
Audit rules are stored in groovy format file. The file is injected into a service and rules are processed by the engine.
POMBA will support the mechanism of separting rules from validation service code, thereby allowing changing the rules without a rebuild or restart of the validation service.
The text of the message displayed for each violation will be kept separately to allow text change without touching the code
