Within the Multi-Site DCAE feature a variety of deployments are discussed:
- Different topics used locally
- Current DCAE/DMaaP approach
- Different events (belonging to different domains) are distributed to different topics - in local DCAE deployment.
- Disaster-Recovery case
- There are two complete ONAP installations, including DCAE platform
- Those deployments are geographically distributed
- The use same topic names
- Topic access credentials are potentially different
- ONAP Regional and Central instance, within a single ONAP enterprise architecture
- There is a single logical ONAP installation, which delegates certain processing to regionalized DCAE platform instances
- Central and regionalized instances are geographically distributed, and they can process the data in parallel
- Potentially different topic names can be used to distinguish local data feeds, and remote data feeds
- VES/HV-VES need to publish same data to different topics (different names), and using different credentials
