Casablanca Release

The Network Discovery microservice was first introduced in Casablanca.

Overview

The Network Discovery microservice allows clients to initiate audits of specified network resource instances. For each request received, the Network Discovery microservice collects information from the network (via other microservices) and returns it to the client.

Use in POMBA

The initial use case for the microservice is to provide support for the Network Discovery Context Builder, which was introduced as part of the POMBA project.

Update

In current Network Discovery microservice development (Dublin), southbound REST API sends OpenStack API requests instead of AAI Enricher API requests.
