Architectural Technical Debt

Runtime: NoneDesign Time - Introducing MOD for Frankfurt; associated risk documented (#3) under Frankfurt Risks

DCAE uses Cloudify based orchestration. Python Platform includes Cloudify which is used for Service Component orchestration. This will continue on Python 2.x as Python 3.x support on cloudify expected 1H2020 (will be assessed for Guilin releasefor Cloudify is not available ( expected AUG'2020; will be evaluated once available and worked as stretch goal for Guilin)
