The ONAP Operations Manager is responsible for configuration and life-cycle management of the ONAP platform.
At its core, OOM leverages the industry leading Kubernetes to provide production-grade container orchestration, resiliency and scalability.
ONAP applications use OOM defined 's standardized Helm Charts to provide:
- customization of ONAP deployments (e.g. select components ONAP subset for Edge)
- unified dependency management
- centralized hierarchical configuration
- resource limit allocations for different sized deployments (development vs production)
Low cost of entry means ONAP can be deployed from a laptop into any public or private infrastructure that is hosting a Kubernetes cluster.

New component capabilities for Dublin (i.e. the functional enhancements)
Below is a summary of functional enhancements. For more details please see OOM Dublin Priorities presentation
from Dublin F2F on Dec. 12 - ONAP Project Developers Event, Dec 10 - 12, 2018, (Virtual Webinars)
Platform Resiliency
- Highly-Available Kubernetes Cluster Deployment
- Improved Persistent Storage resiliency through the use of a new Default Storage Class Provisioner
- Multi-site support using CNI reference integration
- note: applications can take advantage of multi-site by using POD and/or Node (anti)affinity, taints/tolerations, labels per application
...
- Integration of an Ingress Controller for Northbound access control and reduction of NodePorts
- Network Policies (Deferred to El Alto - due to lack of available resources)
- Transparent TLS enablement via Istio reference integration required Istio→AFF integration (de-prioritized by security subcommittee)
Addressed to a degree with M3 Checkpoint item under Security - "Has the project committed to enabling transport level encryption on all interfaces and the option to turn it off?".
With the ability to disable all embedded encryption mechanisms, allows for Service Providers to choose to use Istio or other similar technologies.
Footprint Optimization
- Database Consolidation (DBaaS)
- single shared MariaDB-Galera instance (clients in Dublin: SO, SDNC)
- includes removing mySQL from SDNC in favor of MariaDB-Galera
- single shared Cassandra instance (clients in Dublin: AAI, SDC)
- Portal on shared MariaDB-Galera and Cassandra being investigated (Stretch Goal - has not yet been communicated with Portal Team)
- single shared Postgres instance (deferred to El Alto)
- single shared MariaDB-Galera instance (clients in Dublin: SO, SDNC)
...
- A&AI (complete)
- SO (in progress)
- SDC (in progress)
- SDNC (in progress)
Platform Monitoring
- Improved Health Monitoring and Reporting w/ Integration of Prometheus w/ Operator
- Platform Management UI (deferred to El Alto)
- integrating best-of-bread open source projects to provide platform monitoring and reporting
- deployment management via OOM
Offline Installer
- Delivery of Casablanca Offline Installer in Dublin timeframe
- Working to align OOM charts such that they are compatible with Offline Installer going forward (WIP)
