Our orgs on the PaaS
We generally expect tenants to use a single org on the PaaS for their service. We therefore want to follow the same guidlines for our own apps running on the PaaS. As a result we avoid creating separate orgs for different things, and split our apps into one of 2 orgs as follows:
The admin
org
This is for things that make up part of the platform itself. This includes things like service-brokers, monitoring tools etc.
The govuk-paas
org
This is for things relating to our team. This includes our documentation, team tools (eg rubbernecker) etc.
