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
