      DCAE MOD under assessment for EOL with London release

DCAE MOD was introduced in Frankfurt release to address following requirements:

...

 Platform Maturity (i.e., S3P items)  Kohn London Release Platform Maturity


 Green color → Target level ( details see Platform Maturity below)

      • Performance:  Level 1
      • Stability: Level 2
      • Resiliency: Level 2
      • Security: Level 1+
      • Scalability: Level 1
      • Manageability: Level 1+
      • Usability: Level 1+             

...

As DCAE transformation is underway, two different deployment options will be available. The MVP of DCAE will vary based on deployment choice and will include the necessary subcomponents supporting the primary objectives: meeting platform maturity goals and supporting the use cases.

Helm Deployment (dcaegen2-services)

    •   VESCollector
    •   TCA-gen2
    •   PRH
    •   HV_VES

      DCAE-MOD deployment is optional and will include following component (controlled via helm chart configuration under OOM)

    • Genprocessor
    • MOD/NiFI UI
    • Distributorapi
    • Runtimeapi
    • Onboardingapi

      Note: DCAE-MOD is possible candidate for retirement with Kohn release.


Helm Deployment (dcaegen2-services)

    •   VESCollector
    •   TCA-gen2
    •   PRH
    •   HV_VES
