Multi Cloud Efforts (In progress)

Dublin and Beyond

Deployment Automation Workflow:

• Init

1. Deploy Normalization Microservice as part of ONAP Central
• On Demand
1. Deploy Edge Analytics App in Edge Cloud
2. Create Kafka topic “edge-analytics-central-<id>” in DMaaP (Kafka) broker for publishing alarm from normalization microservice in ONAP format
3. Program DMaaP (Kafka) client in normalization microservice to publish on “edge-analytics-central-<id>”
4. Program DMaaP (Kafka) client in Policy to subscribe to “edge-analytics-central-<id>”

 Operational Workflow:

• Support the following alerts
• Host Aggregate/Cluster CPU usage exceeded a programmed threshold in the edge cloud
• Host Aggregate/Cluster Memory usage exceeded a programmed threshold in the edge cloud
• Host Aggregate/Cluster CPU & Memory usage exceeded a programmed thresholds in the edge cloud
• ONAP Central normalization microservice receives alerts from Edge Analytics App through REST interface
• ONAP Central normalization microservice publishes the above alerts on “edge-analytics-central-<id>” DMaaP (kafka) topic in ONAP format mapping from VM to relevant VNF by querying A&AI
• Policy receives alerts on “edge-analytics-central-<id>” DMaaP (kafka) topic in ONAP format (leverage the current format between DCAE TCA App and Policy -- https://wiki.onap.org/display/DW/TCA+application)
• Policy to perform VNF scale out

 Assumptions:

• Edge Cloud supports OpenStack and K8S
• Edge Analytics App is manually configured – configuration automation involves APP-C and out of scope for this effort
• ONAP Central Normalization microservice is a separate repo in multi-cloud

Dublin Scope

Goal

• Develop basic multi cloud service assurance microservice supporting ONAP Threshold Crossing Alert (TCA) format 
  • TCA application
    • TCA format explained in "Table 1: Format of the Output Alert from the cdap-tca-hi-lo Microservice"
  • Policy R3 Casablanca - Control Loop Operational Policy 
• Hardcoding of various parameters acceptable

Stretch Goals

• vRops integration testing
• ONAP Lab Integration 
• Create Kafka topic “edge-analytics-central-<id>” in DMaaP (Kafka) broker for publishing alert from "multicloud-service-assurance" normalization microservice in ONAP TCA format 

Key Work Items

• Helm Chart and Dockerfile for "multicloud-service-assurance" Normalization Microservice  - Ramki - mostly complete
• vRops Analytics API investigation for TCA w/ future proofing for Smarts - Girish/Ramki - in progress
• Code development for "multicloud-service-assurance" Normalization Microservice - TBD (expected to be 2 weeks or less)
  • Program DMaaP (Kafka) client in normalization microservice to publish on “edge-analytics-central-<id>”
  • Receive TCA Alert using vROps API and publish on “edge-analytics-central-<id>”
