 ## Partitioning
-See [PARTITIONING.md](../PARTITIONING.md) for details on the implemented declarative partitioning.
+See [ARCHITECTURE.md](../ARCHITECTURE.md) for details on the implemented declarative partitioning.
 
-## 🐳 Docker Deployment (Production)
-The `run_test_env.sh` script automatically populates `init_scripts` for the test environment. To deploy this in your own Docker setup:
+## AWS RDS / External Database Testing
 
-1.  **Mount Scripts**: Map the SQL procedures to `/docker-entrypoint-initdb.d/` in your PostgreSQL container.
-2.  **Order Matters**: Scripts execute alphabetically. Ensure they run **after** the Zabbix schema import.
+You can run these partitioning tests against a real AWS RDS (or any external PostgreSQL instance). 
 
-**Example `docker-compose.yml` snippet:**
-```yaml
-services:
-  postgres-server:
-    image: postgres:16
-    volumes:
-      # Mount Zabbix Schema first (e.g., as 01_schema.sql)
-      - ./zabbix_schema.sql:/docker-entrypoint-initdb.d/01_schema.sql
-      
-      # Mount Partitioning Procedures (Prefix to run AFTER schema)
-      - ../postgresql/procedures/00_partitions_init.sql:/docker-entrypoint-initdb.d/02_00_part_init.sql
-      - ../postgresql/procedures/01_auditlog_prep.sql:/docker-entrypoint-initdb.d/02_01_audit_prep.sql
-      - ../postgresql/procedures/02_maintenance.sql:/docker-entrypoint-initdb.d/02_02_maintenance.sql
-      - ../postgresql/procedures/03_enable_partitioning.sql:/docker-entrypoint-initdb.d/02_03_enable.sql
-      - ../postgresql/procedures/04_monitoring_view.sql:/docker-entrypoint-initdb.d/02_04_monitor.sql
-``` 
-The container will automatically execute these scripts on first startup, partitioning the tables.
+### 1. Configure Credentials
+First, create a `db_credentials` file in the `postgresql/` directory. (This file is ignored by Git to keep your passwords safe). 
+Example `postgresql/db_credentials`:
+```bash
+# Admin credentials
+export DB_HOST="your-rds-endpoint.rds.amazonaws.com"
+export DB_PORT="5432"
+export DB_NAME="postgres"
+export DB_USER="postgres"
+export DB_PASSWORD="your_admin_password"
+
+# SSL Configuration
+export DB_SSL_MODE="verify-full"
+export DB_PEM_URL="https://truststore.pki.rds.amazonaws.com/global/global-bundle.pem"
+export DB_SSL_ROOT_CERT="./global-bundle.pem"
+
+# Zabbix credentials to be created
+export ZBX_DB_NAME="zabbix"
+export ZBX_DB_USER="zabbix"
+export ZBX_DB_PASSWORD="zabbix_password"
+```
+
+### 2. Automated Testing
+You can run the same automated deployment script, but instruct it to deploy directly to your RDS instance instead of a local Docker container:
+
+```bash
+cd postgresql/docker
+./run_test_env.sh --pg 16 --zabbix 7.0 --rds
+```
+
+If you want to completely clean up the RDS database and start fresh (terminating existing connections and dropping all data), use the `--rds-drop` flag. You will be prompted to type `yes` to safely confirm the deletion:
+```bash
+./run_test_env.sh --pg 16 --zabbix 7.0 --rds-drop
+```
+
+### 3. Manual Setup & Zabbix Integration
+If you want to prepare the real database for your Production Zabbix Server manually, you can just run the initialization script directly:
+
+```bash
+cd postgresql
+./setup_rds.sh
+# To drop an existing database and start fresh, use:
+# ./setup_rds.sh --drop
+```
+
+The script will automatically connect as the `postgres` user, conditionally download the SSL certificates if needed, and set up the `zabbix` user and database. 
+Upon success, the script will output the exact block you need to copy into your `zabbix_server.conf`, e.g.:
+
+```ini
+DBHost=your-rds-endpoint.rds.amazonaws.com
+DBName=zabbix
+DBUser=zabbix
+DBPassword=zabbix_password
+DBPort=5432
+DBTLSConnect=verify_full
+DBTLSCAFile=/full/path/to/global-bundle.pem
+```
