Architectural Technical Debt
Hardening MOD components (delivered as POC) into mainstream component with redesigned catalog /UI and Policy/CLAMP integrationand Helm charts contributions
Runtime: None
In Honolulu release, DCAE Platform includes Cloudify which is used for (Cloudify and handlers) will be used primarily for dynamic Service Component orchestration. This will continue on Python 2.x as Python 3.x support for Cloudify is not available ( expected AUG'2020; will be evaluated once available and worked as stretch goal for Guilin)All static components deployment will be migrated to Helm. Depending on progress of REQ-439 platform function support via helm, dynamic deployment migration will be dealt in next release.
