2. Bookstack infra with Google auth, on default VPC, RDS AutoBackup Off, Single-AZ, EC2. ≈$51.40 

 Balanced BookStack deployment utilizing an existing VPC with AWS Cognito for authentication . RDS Single-AZ with AutoBackup disabled ensures cost efficiency , while EFS Backup , Secrets Manager , Systems Manager , EC2 , and CloudWatch Logs provide security and monitoring. 

 

 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 .
