+# AWS RDS
+
+Deploy managed relational databases with Amazon RDS.
+
+## Create Database
+
+```bash
+aws rds create-db-instance \
+  --db-instance-identifier mydb \
+  --db-instance-class db.t3.micro \
+  --engine postgres \
+  --engine-version 15 \
+  --master-username admin \
+  --master-user-password secretpassword \
+  --allocated-storage 20 \
+  --storage-encrypted \
+  --vpc-security-group-ids sg-xxx \
+  --db-subnet-group-name my-subnet-group \
+  --backup-retention-period 7 \
+  --multi-az
+```
+
+## Parameter Groups
+
+```bash
+aws rds create-db-parameter-group \
+  --db-parameter-group-name custom-pg \
+  --db-parameter-group-family postgres15 \
+  --description "Custom PostgreSQL parameters"
+
+aws rds modify-db-parameter-group \
+  --db-parameter-group-name custom-pg \
+  --parameters "ParameterName=max_connections,ParameterValue=200,ApplyMethod=pending-reboot"
+```
+
+## Snapshots & Recovery
+
+```bash
+# Create snapshot
+aws rds create-db-snapshot \
+  --db-instance-identifier mydb \
+  --db-snapshot-identifier mydb-snapshot
+
+# Restore from snapshot
+aws rds restore-db-instance-from-db-snapshot \
+  --db-instance-identifier mydb-restored \
+  --db-snapshot-identifier mydb-snapshot
+```
+
+## Read Replicas
+
+```bash
+aws rds create-db-instance-read-replica \
+  --db-instance-identifier mydb-replica \
+  --source-db-instance-identifier mydb
+```
+
+## Best Practices
+
+- Enable Multi-AZ for production
+- Use encryption at rest
+- Implement automated backups
+- Use read replicas for read scaling
+- Store credentials in Secrets Manager
