Cloud Infrastructure for Distributed Clouds: ONAP R3+ Cloud Infrastructure Modeling; Cloud Infrastructure Aggregate Representation Classes
ONAP Component | Life Cycle Phase | Enhancements |
---|---|---|
Policy | Design | Define Distributed Cloud Infrastructure Placement Policies (Note 3)
|
Multi-Cloud | Deploy | Implement Distributed Cloud Infrastructure Capability Discovery (Note 1, Note 2) |
A&AI | Deploy | Implement Standardized Distributed Cloud Infrastructure Object Hierarchy & Capability Database
The Multi-Cloud Distributed Cloud Infrastructure Capability Discovery process will populate the aforementioned database |
OOF | Deploy | Execute Distributed Cloud Infrastructure Placement Policies for Optimized Service/VNF Placement across Cloud Regions (Note 4) |
Note 1:
- Configured Capacity and Utilized (or Currently Used) Capacity are managed by the specific cloud.
Note 2:
- Cloud SW Capability example
- Cloud region "x" with SR-IOV, GPU, Min-guarantee support
- Cloud region "y" with SR-IOV support
- Cloud HW Capability example
- Resource cluster "xa" in Cloud region "x" with SR-IOV and GPU support
- Resource cluster "xb" in Cloud region "x" with GPU support
- Resource cluster "ya" in Cloud region "y" with SR-IOV support
Note 3:
- 5G Service/VNF placement example
- Constraints used by Optimization Framework (OOF)
5G CU-UP VNF location is fixed to a specific physical DC based based on subscriber group
5G CU-CP VNF to 5G CU-UP VNF Data Center connectivity latency cannot exceed certain value
- Optimization Policy used by OOF
Choose optimized cloud region (or instance) for the placement of 5G CU UP/CP for subscriber group based on the above constraints
- Constraints used by Optimization Framework (OOF)
Note 4:
- For the 5G Service/VNF placement example in Note 3
- 5G CU-UP VNF maps to a specific Cloud region & Physical DC End Point
- 5G CU-UP VNF maps to one or more Cloud region(s)
End-to-end use case: Definition, Creation & Management of Network Slice
Edge Automation Requirement:
Support three types of slices in the Cloud Infrastructure (Definition Reference: https://kubernetes.io/docs/tasks/configure-pod-container/quality-service-pod/)
- Guaranteed (hard isolation)
- Burstable (soft isolation)
- Best Effort (no isolation)
Assumption:
- This uses the current Generic VNF workflow in SO
