   6 MultiCloud infra_workload API
   7 ===============================
   8
   9 we have two purposes for this API:
  10
  11 #. Intergrate SO and Multicloud.
  12 #. Generic API for SO to talk to different Multicloud plugins.
  13
  14
  15 Problem Description
  16 ===================
  17
  18 Currently HPA flavors are returned by OOF  to SO and SO copies these flavors in
  19 the Heat template before sending the Heat template to Multicloud.  In Casablanca
  20 instead of SO making changes in the Heat template the flavor information will be
  21 provided to Multicloud and Multicloud will pass these as parameters to HEAT
  22 command line.
  23 The detail design refer to https://wiki.onap.org/display/DW/SO+Casablanca+HPA+Design
