4. Known system limitations
Architectural Technical Debt
Hardening MOD POC into mainstream component with redesigned catalog/UI and Policy/CLAMP integration
Runtime: None
DCAE Platform includes Cloudify which is used for 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)
