• Onboarding (design)
  • The mS owner identifies the input and output stream in spec file. The actual topic/feed and access credentials are
• Runtime
  • Plugins (Dmaap and K8SPlugin)
    • These are cloudify plugins bootstrapped into DCAE Cloudify Manager during platform instantiation. The plugins provides interface/function to implement specific function. The plugins are referenced based on node type in the blueprint (deployment artifact for DCAE MS).
  • DMaap Bus Controller (DBCL)
    • DMaap Bus Controller provides API to serve new feed and topic creation requests
  • ConfigBindingService
    • DCAE Platform Component providing standardized API for DCAE Microservice to retrieve configuration including Dmaap topic/feed configuration dynamically provisioned.
  • Consul KV
    • Key-Value store where all service component configuration are stored during deployment.

EL-Alto Usecase

The 5G Bulk PM components, namely DataFile Collector and PM-Mapper were deployed using Dmaap Plugin integration for El-Alto .<usecase reference to be added>as prototype to validate the secure & dynamic feed/topic provisioning feature.

The complete flow for the usecase 5G Bulk PM flow can be referred here - 5G - Bulk PM (Casablanca carry-over items).

This usecase enabled validation of both DMaap Message-router and Data-Router case for both publisher and subscriber MS.

DataFile Collector : Subscribe from MR topic, publish files into DR feed

PM-Mapper : Subscribes from DR Feed; publish into MR topic

Demo

Scope

• Review blueprint configuration for DFC
• Deployment for DFC (via dashboard)
• Validation of new feed created
• Review blueprint configuration for PM-Mapper
• Deployment of PM-Mapper (via dashboard)
• Validation of new feed/topic created
• Sample data flow
