A Serverless Warehouse Whose Spend Limit Does More Than Log
An Amazon Redshift Serverless namespace and workgroup: customer-managed encryption, SSL required, all three logs exported, and the admin password generated and held by Secrets Manager. AWS accepts plaintext connections by default and a usage limit's default action only logs the breach, so SSL is set at creation and the spend limit's action has to be chosen: alert or stop.

Documentation
aws-redshift-serverless
A serverless data warehouse on Amazon Redshift Serverless. Works with Terraform and OpenTofu
(>= 1.6), aws provider >= 6.0, < 7.0.
A serverless warehouse has no spend ceiling unless you set one. spend_limit is required, and its action has no default because AWS's default, log, records the breach and keeps spending.
Plaintext connections are accepted by default. AWS documents that a workgroup accepts connections with or without SSL; require_ssl is set at creation, because changing it later restarts the workgroup.
No logs leave the namespace unless named. Connection, user and user-activity logs are all exported, with user-activity logging switched on.
The admin password never passes through Terraform. Secrets Manager generates and holds it, encrypted with your key.
Public access is off, and turning it on requires accept_public_access.
Verification
Static validation runs tofu fmt, init, validate, tflint and checkov.
This module has not yet had a live test, so it is published as statically
validated with its live test pending and does not carry the live-tested mark.

Related modules
aws-keyspaces
point_in_time_recovery defaults to DISABLED and Keyspaces has no snapshots or automated backups, so off means a dropped table is simply gone. PITR on, a customer-managed key, and the two one-way doors - client-side timestamps and TTL - named rather than set quietly.
aws-database-proxy
Amazon RDS Proxy in front of an RDS instance or Aurora cluster: TLS required, clients authenticate with IAM tokens while the proxy reads the password from Secrets Manager, through a role limited to those secrets. Debug logging writes SQL statement text to the logs, so it is off unless that is accepted. End-to-end IAM removes the stored password entirely.
aws-dax-cache
DynamoDB Accelerator with TLS and encryption at rest. DAX leaves both off by default, and neither can be turned on for an existing cluster, so a fix means a new cluster. This module also creates its own security group (DAX otherwise uses the VPC default), a service role limited to the named tables and their indexes, and states that writes bypassing DAX leave stale reads until the TTL.
aws-neptune
Neptune has no user, no password and no GRANT. Authorization is IAM and it defaults to OFF, so anything that can reach port 8182 can read every edge and drop the lot. IAM auth on, storage encrypted, and the audit log driven from one variable because its two halves live in different resources and either alone logs nothing.
aws-dms
ssl_mode defaults to none in AWS, so a task reads your entire production database and writes it elsewhere unencrypted. This defaults to require, refuses none unless stated, and pushes the credential into Secrets Manager rather than state.
aws-quicksight
A QuickSight subscription on Enterprise edition through IAM Identity Center, with admin, author and reader groups, termination protection on because unsubscribing deletes every dashboard, and a VPC connection with its own role so a private database stays private. The authentication method is permanent; Standard edition and QuickSight-managed users are accepted by name.
