This product has charges associated with it for hardening, security configuration, and support.
PostgreSQL is the world's most advanced open-source relational database - a battle-tested, ACID-compliant SQL engine with JSON, full-text search, and extensions. Unlike bare PostgreSQL AMIs that ship with no password set, plaintext connections, and authentication you have to lock down yourself, this Lynxroute build is security baked in: scram-sha-256 auth required, a superuser password and a sample database generated at first boot, native TLS with a per-instance certificate, no trust auth anywhere, UFW firewall, and a CIS Level 1 hardened Ubuntu 24.04 LTS base.
It also bundles the pgAdmin 4 web UI: manage your database from any browser over HTTPS behind an nginx TLS perimeter, with an admin login generated at first boot.
A locked-down SQL database with a browser admin UI, safe from first boot. PostgreSQL license - fully auditable, no vendor lock-in.
This is a repackaged software product wherein additional charges apply for hardening, security configuration, and support.
WHAT IS POSTGRESQL
PostgreSQL is a powerful, open-source object-relational database management system, implemented in C as a robust multi-process server with multi-version concurrency control (MVCC). It offers fully ACID-compliant transactions, the SQL standard plus rich extensions, native JSON and JSONB, full-text search, window functions, common table expressions, materialized views, table partitioning, GiST/GIN/BRIN indexing, stored procedures in multiple languages, logical and streaming replication, and a mature extension ecosystem (the contrib modules pg_stat_statements, pgcrypto and uuid-ossp ship in the image). It speaks the standard wire protocol, so it connects from every language through libpq, JDBC and ODBC drivers. Data is persisted on disk with write-ahead logging and page checksums enabled. Running it yourself in your own VPC keeps your data inside your AWS account rather than a managed service. PostgreSQL license, no vendor lock-in.
WHAT THIS AMI ADDS
Security hardening:
scram-sha-256 auth required - the postgres superuser password plus a sample application database and role are generated at first boot, never a default or empty password
No trust authentication anywhere - every host connection in pg_hba.conf requires scram-sha-256
Native TLS enabled at first boot with a per-instance self-signed certificate - no shared private key is baked into the image; clients connect with sslmode=require
Listens for VPC-internal access only - port 5432 is governed by your Security Group, not exposed to the internet
UFW firewall - SSH on 22 only; port 5432 governed by your Security Group
fail2ban, AppArmor
CVE scan - every image is scanned for vulnerabilities before release
Web administration (pgAdmin 4):
pgAdmin 4 web UI in server mode - browse schemas, run SQL, manage roles and backups from your browser
Served only over HTTPS behind an nginx TLS perimeter on 443 (per-instance self-signed certificate; swap in your own with certbot)
pgAdmin itself binds to 127.0.0.1 only - never exposed directly; the admin email and a random password are generated at first boot
No new database port is opened - the UI is reached on 443, governed by your Security Group
OS hardening (CIS Level 1):
CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown
CIS Conformance Report at /etc/lynxroute/cis-report.html
CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md
Highlights
PostgreSQL security baked in: scram-sha-256 auth required, superuser password and sample database generated at first boot, native TLS with a per-instance certificate, no trust authentication - unlike bare PostgreSQL AMIs that ship with no password set and plaintext connections you have to lock down yourself.
CIS Level 1 hardened Ubuntu 24.04 LTS: auditd, fail2ban, AppArmor, SSH key-only, IMDSv2 enforced. CVE-scanned before every release. SBOM (CycloneDX) and CIS Conformance Report included.
Bundled pgAdmin 4 web UI: manage schemas, run SQL, and handle backups from any browser over HTTPS (nginx TLS perimeter on 443; pgAdmin binds to loopback, admin login generated at first boot). The world's most advanced open-source SQL database - ACID, JSON/JSONB, full-text search, replication. PostgreSQL license, no vendor lock-in.

You pay by the hour for the software running on your chosen Amazon EC2 instance size. The five options are all instance types, not feature tiers. Every option ships the same hardened PostgreSQL 18 image, so pricing changes only with the compute you select. The t3.small, t3.medium, and t3.large are burstable instances suited to lighter or variable workloads. The m6i.large and m6i.xlarge are general-purpose instances with more consistent compute and memory. Your hourly cost scales with the instance's size and capacity. You run and stop instances as needed, with no upfront commitment.
Top-of-mind questions for buyers
Am I charged the hourly software fee when my instance is stopped?
The software fee meters running time. A fully stopped instance does not accrue the hourly software charge. You may still pay underlying AWS storage fees for the attached volume while the instance is stopped. Charges resume once you start the instance again.
What do I get for the hourly price on each instance option?
Each option maps to one Amazon EC2 instance running the hardened PostgreSQL 18 image. The t3 sizes are burstable with varying vCPU and memory. The m6i sizes are general-purpose with steadier compute. Larger sizes carry more vCPU and memory, so the hourly rate rises with capacity.
What security features are included in the image at no extra charge?
Every instance ships with CIS Level 1 hardened Ubuntu 24.04, a CVE scan report, a software bill of materials, and a CIS Conformance Report. Unique credentials generate at first boot. A host firewall, intrusion prevention, and audit logging are pre-configured. These are bundled, not billed separately.

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
PostgreSQL 18.4 + pgAdmin 9.15 - adds the pgAdmin 4 web administration UI (server mode) behind the nginx TLS perimeter on 443 (/pgadmin4/); pgAdmin listens on loopback only, admin login generated per-instance at first boot. PostgreSQL 18.4 unchanged.
Open port 5432 in the Security Group ONLY to your trusted app-tier sources in the same VPC (never 0.0.0.0/0); open 443 ONLY to the trusted IPs that will use the pgAdmin web UI
Connect from an app server in the same VPC using the private IP, port 5432, and sslmode=require
pgAdmin web UI: browse to https://<PUBLIC_IP>/pgadmin4/ and log in with the admin email + password from the credentials file (the certificate is self-signed by default)
The database requires scram-sha-256 password authentication, native TLS is enabled, and access to port 5432 is governed by your Security Group - never expose 5432 to the public internet. The pgAdmin 4 web UI is the only browser-facing component; it is served on 443 only, binds to loopback internally, and should likewise be scoped to trusted sources.
The postgres superuser password and the sample appdb/appuser credentials are saved to
/root/postgresql-credentials.txt at first boot. A per-instance self-signed TLS certificate
is generated at first boot; for production, replace /etc/postgresql/18/main/server.crt and
server.key with a CA-signed pair (key owned by postgres, mode 600) and restart the service.
