Hi All,

With AppFactory moving to a single Stratos, there are some changes to
tenant creation as well as resource creation. Following diagrams[1] shows
how the existing tenant creation and  registries being shared among three
different cloud environments.

​Here in the existing governance model, there are separate databases for
config, governance and userstore for three cloud environments. Tenant
creation as well as cartridge subscription happens in all three Stratos
instances by listening to message broker topic.
Separate governance instances were introduced to offload resource
management from stratos.

​
​With the new single Stratos deployment [2] followings are the proposed
changes.

1.)  Stratos share appfactory userstore and governance. Hence there's no
need to create tenant in Stratos side.

2.) Tenant creation happens inside dev, test, prod greg; by listening to
message broker topic

3.) There's an additional message going to MB for cartridge subscription,
and it happens in Stratos side.

With the above changes it's important to notice that the tenant creation
and cartridge subscription happens as separate processes. Appreciate your
feedback on the proposed method.
