Production and Staging Isolation
There are various reasons and approaches to isolating different environments. Regardless of the motivation, Fly Organizations may be a good way to isolate more sensitive environments.
Fly Organizations
Read up on Organizations in Fly.io. An org has members, separate billing controls, and separate private networks. For teams that want to separate production environments from staging and development, the “org” is a great starting point and draws a hard line separation.
When setting up a Fly.io account, by default, applications are deployed to a “personal” account. That works great for individuals but when you are ready to share access to apps among multiple people, use orgs.
Production Fly Organization
Create an Organization in Fly.io for your team and apps. Creating an organization makes it easy to invite other developers, manage billing with a company credit card, and deploy apps to a shared environment.
Use the Dashboard to manage your organizations, members and invites.
The flyctl CLI also supports organization operations.

Invite your team members to the Organization.

Networks in an Organization
Multiple apps can be deployed to an organization. Any applications deployed to the same organization are accessible to each other in the private network.
Staging Organization
Create additional organizations for “staging” or “testing” environments to fully isolate them from the production environment.
fly orgs create <my-org-staging>
Databases are applications as well. Create a new Postgres cluster in a staging organization for applications deployed in the organization. Multiple apps can share the Postgres server and the apps can create their own databases in a server in the staging org.
Depending on your needs and usage, a staging database cluster can be smaller than the production one as it likely receives less traffic.
Create a Postgres cluster in your staging org:
fly postgres create
As a suggestion, if the production database is named my-app-db, the staging version could be named my-app-db-stage.
