Overview
PostgreSQL 16 (Hardened) on Amazon Linux 2023 is a production-ready, security-hardened image of the PostgreSQL relational database, maintained and supported by Derek Coleman & Associates Incorporated.
This is repackaged open-source software. PostgreSQL is developed by the PostgreSQL Global Development Group and distributed under the PostgreSQL License (a permissive OSI-approved license). This product bundles unmodified upstream PostgreSQL 16 on a hardened Amazon Linux 2023 base; the charges associated with this listing are for image hardening, continuous patching, vulnerability scanning, and business-day support - not for the underlying open-source software, which remains free.
Hardening baseline: minimal package footprint, SSH key-only access (password authentication disabled), IMDSv2 enforced, and no default database passwords (local peer/socket auth; remote access on port 5432 stays closed until you configure pg_hba.conf and open it to trusted CIDRs). Images are rebuilt, scanned for HIGH and CRITICAL vulnerabilities, and republished on a regular cadence. The data directory initializes on first boot under /var/lib/pgsql; manage the service with systemd and administer locally with: sudo -u postgres psql.
Highlights
- Security-hardened at build time: minimal packages, key-only SSH, IMDSv2-only, no default database passwords, remote access closed until you configure it.
- Continuously patched: images are rebuilt, vulnerability-scanned, and republished on a regular cadence so new launches start current.
- Production-ready: systemd-managed PostgreSQL 16; the data directory auto-initializes on first boot under /var/lib/pgsql.

64-bit (x86) Amazon Machine Image (AMI)
Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
[Important] Initial release. PostgreSQL 16 on Amazon Linux 2023, hardened baseline; all OS packages current at build.
Additional details
Usage instructions
Launch from AWS Marketplace (1-Click or EC2 console). Connect via SSH with your EC2 key pair: ssh -i <key> ec2-user@<public-ip>. The data directory initializes on first boot; administer locally with: sudo -u postgres psql. Remote access (port 5432) and authentication are a deliberate customer configuration step - edit pg_hba.conf and postgresql.conf, then open 5432 to trusted CIDRs only. Root login is disabled; use sudo. There are no passwords anywhere in this product.
