ONAP high level design requirements
Today new emerging infrastructures based on kubernetes are becoming very popular. ONAP components shall support CNAs/CNFs artifacts, cloud native service models and relevant distribution/management. Given the fact that K8s has its own orchestration capabilities that partially overlap with ONAP capabilities, it is expected that ONAP development focuses first on aspects not covered by K8s. The envisioned scenario is based on both CNFs and PNFs. Moreover kubernetes provide a declarative approach to the orchestration of many aspects such as resource provisioning, resource scaling and resiliency and can be enhanced with many add-ons that seamlessly provide other features such as application control, communication robustness etc (e.g service mesh by Istio). ONAP provides a good level of flexibility in service orchestration (e.g. a la carte, Macro and E2E orchestration approaches) but the framework requires specialized skills to implement unforeseen orchestration patterns that may slow down new service design and deployment. It is therefore required that ONAP functional module adopts a declarative approach and native support for CNAs artifacts to avoid time to market bottlenecks.
New component capabilities for Guilin, i.e. the functional enhancements, if applicable
- Enable ONAP potential users to understand ONAP strategy and main goals
- Enables ONAP components to enable users to easily design a new service by a unified design environment
- Enables ONAP components to let users to reduce time to market when introducing a new service with no manual intervention on run-time code
- Enable ONAP components to be ready to manage future proof services based on CNAs and CNFs and Cloud native infrastructure
