Key Requirements
To support latency-sensitive, high-bandwidth network functions and applications driven by 5G, Edge Computing, VoLTE use cases some of the key requirements from a Cloud Infrastructure perspective are
1) A single Cloud Region needs to be able to manage multiple distributed (typically Edge) physical DCs
2) Standardized representation of Multi-vendor Cloud Object Hierarchy
- Aggregate objects (Cloud Region, Tenants, DCI Overlay etc.)
- Atomic objects (VMs, Containers etc.)
- Resource (CPU, Memory, Network etc.) allocation statistics and resource utilization metrics
3) Standardized representation of Multi-vendor Cloud Analytics
- Events (E.g. VM Power On/Off),
- Alerts (E.g. Cloud Region CPU Usage exceeds threshold) and
- Faults (E.g. Loss of Redundancy from a Host NIC perspective)
- Policies for correlating between various Events, Alerts, Faults
4) Near-real-time Streaming Data Management
- Resource (CPU, Memory, Network etc.) Utilization Metrics
- Analytics (Events/Alerts/Faults)
5) Inter-Cloud (typically Edge) Workload (especially Data Plane) Placement/Scheduling/Change Management decisions to leverage metrics and analytics information at an aggregate object level
