Distributed Edge Cloud Infrastructure Object Hierarchy (Stretch Goal - Beyond Casablanca)
Value:
- Fine grained resource management & analytics for Distributed Edge Clouds
...
- Multi-Cloud Policy Framework
- Assist OOF in target cloud region selection for VNF placement (aka homing) through intent
Cloud Agnostic Intent (Policy) Execution Workflow - Steps 1- 4
- Dynamically modify the cloud specific VNF deployment template based on cloud-specific realization of the specified intent (e.g. Infra HA for VMs within a VNF could have different realizations across different clouds)
Cloud Agnostic Intent (Policy) Execution Workflow - Step 5
- Assist OOF in target cloud region selection for VNF placement (aka homing) through intent
Intent Support
Single realization option per Cloud Region for the specified Intent
- Impact Projects:
- Multi-Cloud (Highest), OOF, SO (Minimal)
- End-to-end use case demonstration:
- vCPE (no additional implementation dependency), vDNS
- Types of intent supported (through OOF Policy)
- "Infrastructure High Availability for VNF"
- "Infrastructure Resource Isolation for VNF": "Burstable QoS"
- for VNF"
- "Infrastructure Resource Isolation for VNF": "Burstable QoS"
