Documentation
aws-elasticache-redis
Amazon ElastiCache for Redis / Valkey, cluster mode disabled (a single
primary with optional read replicas). Works with Terraform and OpenTofu
(>= 1.6), AWS provider >= 6.0, < 7.0. Secure by default and self-contained:
encryption at rest and in transit are both on, the cache is never publicly
reachable, and the networking pieces (subnet group + security group) are created
for you — falling back to the account's default VPC so a minimal cache applies
with just a name.
Secure defaults:
- Encryption at rest on (
at_rest_encryption_enabled = true); use a customer-managed key viakms_key_id, otherwise the AWS-managed ElastiCache key - Encryption in transit (TLS) on (
transit_encryption_enabled = true); optionalauth_tokenadds Redis AUTH on top (the token is never an output) - No public exposure — access is via a module-created security group that
opens the cache port only to
allowed_cidrs/allowed_security_group_ids(no ingress at all by default) - Automatic minor version upgrades on, to pick up security patches
- Footgun guards (plan-time preconditions): Multi-AZ implies automatic failover,
automatic failover implies
num_cache_clusters >= 2,auth_tokenimplies TLS,kms_key_idimplies at-rest encryption
Cost note: the default cache.t4g.micro single node is the cheapest option
(~$0.016/hr). HA (replicas + automatic_failover_enabled + multi_az_enabled)
is off by default — opt in for production.
Security notes
- Clients must speak TLS while
transit_encryption_enabledis on. Add anauth_tokenfor password auth; the token is supplied viaTF_VAR_auth_tokenor a secrets manager and is never exposed as an output. - Keep
allowed_cidrs/allowed_security_group_idsas tight as possible — prefer granting an application security group over a CIDR range. - For real deployments pin
subnet_idsto private subnets instead of relying on the default-VPC fallback.
Requirements
- Terraform or OpenTofu
>= 1.6 hashicorp/aws>= 6.0, < 7.0

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.
