We're considering installing the API Developer Portal 4.2. Question is whether we should deploy a single Portal for all of our deployment environments (dev, test, sys test, uat, prod) or deploy two Portals, one for dev, test, sys test, uat and a second Portal for prod? The documentation describes the ability to create one or more tenants. Could tenants be used to separate non-prod and prod on a single Portal? How are you all handling the difference between dev and prod? Together or separate?
You can create another tenants in the Portal.So, you can have non-prod and prod on a single Portal.
API Portal can deploy API to multiple tenants.
