Retirement/Deprecation

  • Acumos Adapter

      DCAE MOD under assessment for EOL with London release

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

    1. Simplified and streamlined onboarding for DCAE components/microservice and distribute the deployment artifact with DCAE-Core Platform (Cloudify)
    2. Provide Common Catalog for reusable DCAE microservices for Designer to leverage
    3. Enable automated onboarding for ML microservices from Acumos. 

With DCAE platform transformation feature, requirement #1 and #2 are less critical as the onboarding/deployment are easily managed through Helm-Charts and catalog supported through Chartmuseum (or any other registry)/With Also with Acumos project archived under LF (end of 2021), DCAE team will be assessing the need for continuation/support of DCAE MOD going forward.  

Note: Certain MOD components are on java8 due to upstream dependency with Apache/Nifi project on java8 and have SECCOM exception currently.

Info
titleUpdate 07/19/22

Following DCAE Team meeting discussion and ARC reviews, DCAE-MOD has been identified for retirement with London release. Official communication sent to ONAP DL's - https://lists.onap.org/g/onap-tsc/topic/dcae_mod_eol_with_london/92490689

Longer term roadmap

Complete With DCAE transformation initatives and backlog items.

...

Helm transformation initiate completed, achieved the major goal on platform simplification. As ONAP progresses for supporting new usecase, will assess them for support.

Following are some initiatives under consideration

    • Policy/CLAMP: Continue integration for Control Loop design for Helm-based deployment of DCAE Services*
    • DCAE: Chart migration from OOM repo to DCAE & ONAP CI/CD integration for helm chart builds
    • DCAE MOD support for Java11 compatibility Assess DCAEMOD platform continued support/retirement
    • Prometheus Integration
    • TICK/ELK Integration
