1. Bookstack infra with default auth

1. Bookstack infra with default auth, on default VPC, RDS AutoBackup Off, Single-AZ, EC2. ≈$45.40 

 This BookStack infrastructure is optimized for cost efficiency by utilizing an existing VPC instead of provisioning a new one. AWS Cognito authentication is disabled , relying on standard authentication mechanisms. The database is hosted on RDS with a Single-AZ deployment , and AutoBackup is disabled to minimize costs. Additionally, the infrastructure includes an EC2 instance , EFS Backup for persistent storage, Secrets Manager and Systems Manager for secure configuration management, and CloudWatch Logs for monitoring and troubleshooting. 

 

 You can always update the current stack using a Change Set to enable: 

 

 • RDS Multi-AZ ( MultiAZ=true ) for high availability, 

 • RDS AutoBackup ( AutoBackup=true ) for automatic backups, 

 • RDS Deletion Protection ( DeletionProtection=true ) to prevent accidental deletion. 

 However, you cannot switch from the default VPC to a custom one because the CIDR block differs , preventing the stack from being updated. 

 For instructions on updating the stack using a  Change Set , please refer to the dedicated guide .
