heat in multi region configuration
Hi,
I would like to understand heat usage in multi region configuration (on Juno release).
My assumptions:
- two Regions: Region1 and Region2
- one heat service in each Region
- one common keystone
- one common dashboard
- other services defined in both regions (e.g. neutron in region1 and second neutron in region2)
- one tenant (half of the resources in Region1 and half of the resources in Region2)
- instances from both regions can connect to each other using private network defined in the tenant
- heat will be triggered from instances defined in the tenant
Questions:
- Are my assumptions correct?
- Two heat services (one in each region), heat wll be triggered from instances so:
- is it possible to trigger heat service defined in region1 from the instance defined in region2? If yes how we can do that? How we can specify which heat should be used?
