There are two different AWS Accounts

• Production
• Development

There are some manually provisioned resources in both accounts.

• VPC (Default) is used for both environments
• IAM is managed manually for Pulumi stacks in Github Actions (see ima/github-actions.json)
• Route 53 Hosted Zones (quadratic-preview.com and quadratichq.com)
• Certificate ARN for both Domains

Those resources are shared between stacks.

All our application resources are created by the pulumi stack.
