Activity Description:
Starting with Analytics, describe the options and recommendations for distributing management (ONAP etc.) functions.
Problem Statement:
- Management Workloads
- Currently, Multiple Orchestrators for Management Workloads (SDC, SO, OOF etc.)
- ONAP Central Management – OOM
- Analytics Central/Distributed Management – DCAE (ONAP, SP internal, Third Party)
- There is an opportunity to get some alignment across multiple orchestrators which will be greatly beneficial especially in Distributed Edge environment
- Currently, Multiple Orchestrators for Management Workloads (SDC, SO, OOF etc.)
- Managed Workloads
- Fully Support for containerized network functions (work in progress)
- Support for non-network functions (VM and Container based), e.g. vProbe, Automation Apps
Solution Direction:
- Management Workload:
- Align on a single orchestrator solution for all management workloads
- Managed Workload:
- Enhance SDC, SO, A&AI, MC etc. to support containerized functions
- Leverage ONAP for deploying and managing non-network functions
- Longer-term:
- Explore feasibility for orchestration alignment between managed workload and management workload
- Cloud-Native-foundation:
- Leverage K8S (Operators, Custom Resource Definitions etc.) for Distributed Systems Management
- Image management – at scale rolling upgrade
Policy/Configuration change – notify only deltas
- Leverage Istio Service Mesh (Distributed Tracing etc.) for Component Performance Management
- Leverage K8S (Operators, Custom Resource Definitions etc.) for Distributed Systems Management
Definition of done:
- This activity is closed when there is a:
- Description of alternative concepts for distributing the ONAP functionality.
- A recommendation for which alternatives to pursue (and when).
Expected Timeframe:
This activity is expected to conclude at/before the start of April, 2019 by the ONAP Architecture meeting at ONS.
