The diagram below shows the most straightforward solution in terms of data management. In this case, the entire system is deployed to a single account, and Role-Based Access Control (RBAC) used to maintain separation.

The main drawback is the potential to accidentally grant access to a production schema to a non-production role. However, this risk can be eliminated by scripting grants and using a strong naming convention between environments. This could be used (for example) to generate the script to grant PROD_WORKING_READ role to PROD_DATA_ANALYST. As the actual command is generated, it would automatically prevent granting the PROD access to a DEV role.
