Management application: Can be ONAP component or equivalent component from third parties
Solution Options
Management Apps as traditional Apps/VNFs - Option 1 | AT&T EOM - Option 2 | Cloud Native K8S Ecosystem (which includes current OOM helm charts ) - Option 3 |
---|---|---|
Existing infrastructure that is available in ONAP | EOM: ECOMP Subsystem that deploys and | Cloud Native K8S Ecosystem - https://landscape.cncf.io/ ONAP OOM Project - Prescriptive Helm Charts for various ONAP management plane components |
Analysis of Options 1, 2, 3
Option 1 is not considered further due to lack of backward compatibility with existing management plane orchestration solutions.
It was considered pragmatic to synergize Options 2 and 3 to produce a best of breed solution
