This is a repackaged open source software product wherein additional charges apply for a pre-hardened, AWS-optimized image with verification reports and maintenance. This AMI delivers PostgreSQL 16 on a Rocky Linux 9.8 base hardened and tuned for EC2 by Easycloud-with security scan reports and SBOM.
Overview
This is a repackaged open source software product wherein additional charges apply for a pre-hardened, AWS-optimized image with verifiable evidence and maintenance. PostgreSQL 16 runs on a Rocky Linux 9.8 base hardened, tuned for Amazon EC2 workloads, and shipped with a complete evidence pack and Software Bill of Materials (SBOM).
Value-Added Features
PostgreSQL 16 Deployment:
-
Best-Practice Deployment: PostgreSQL 16 installed and enabled following official AWS and PostgreSQL guidelines, ready to accept connections on first launch.
-
Secure Defaults, Zero Configuration Drift: The upstream default peer authentication is preserved and network access is restricted to localhost, so the database is never exposed to the public internet by accident.
-
Bloat-Free Data Layer: CPU and memory go to query planning and transaction processing rather than unused system services.
Hardened Operating System Base:
-
Security Hardening: SELinux enforcing with the targeted policy, ICMP redirects disabled, unused kernel modules blocked, and a shorter SSH login window.
-
Fully Patched at Release: Zero packages with a pending update at build time, verified. The complete CVE scan ships inside the image.
Comprehensive Evidence Pack:
Every AMI carries an evidence pack under /opt/optimization-report/:
- Tuning_Parameters.txt: Every performance tuning parameter, each shown against the Rocky Linux default, with how to undo it.
- Security_Parameters.txt: SELinux and every security setting, each shown against the Rocky Linux default, with how to undo it.
- sbom.spdx.json: Software Bill of Materials in SPDX format, generated from the RPM database.
- cve_scan.txt / cve_scan_full.txt.gz: Vulnerability scan reports categorizing CVEs by upstream patch availability.
- key_files.sha256: SHA-256 checksums of the key configuration files described in the reports, so the delivered state can be verified.
- README.txt: Index of artifact contents, operational guidelines, and configuration defaults, including the installed software.
Reliability Validation:
- Validation Testing: Functional verification on clean AMI launches through multi-round integration testing, covering the complete database lifecycle with SELinux enforcing.
AWS Network & Kernel Tuning:
-
Network Stack: TCP BBR congestion control with fair queueing, increased connection backlogs, buffer adjustments, and MTU probing enabled.
-
System Tuning: Red Hat tuned daemon active with a custom cloud profile, transparent hugepages set to madvise, and modified memory/EBS writeback parameters.
-
EC2 Integration: NVMe I/O timeouts, Amazon Time Sync (chrony), IRQ balance daemon, and size-capped persistent journald logging.
Operational Tools:
- Preinstalled Tools: AWS SSM Session Manager enabled, CloudWatch Agent installed (disabled by default).
Maintenance:
- Maintenance Specifications: Rebuilt and updated bi-weekly to monthly incorporating upstream PostgreSQL and Rocky Linux 9.8 security updates, with artifact documentation refreshed per release.
About PostgreSQL 16
One of the world's most advanced open-source relational database systems, known for strict ACID compliance, a rich SQL feature set, and deep extensibility through JSONB, full text search, and foreign data wrappers. Version 16 improves parallel query execution and logical replication, serving transactional and analytical workloads alike, and integrates with ORM layers such as Hibernate and SQLAlchemy and frameworks including Django and FastAPI.
About Rocky Linux 9
Built directly from RHEL 9 source code for binary compatibility with the Red Hat 9 ecosystem, with predictable update cadences and a maintenance lifecycle through 2032. Any application compiled, certified, or documented for RHEL 9 runs without modification, and the platform is structurally aligned with AlmaLinux, CentOS Stream, and legacy CentOS deployments.
The Perfect High-Performance Data Layer: By starting with a bloat-free Rocky Linux 9 installation, maximum CPU and memory are dedicated entirely to query planning and transaction processing. This makes it the perfect, conflict-free foundation for relational and analytical workloads alongside MySQL, MariaDB, Percona Server, Amazon Aurora, Oracle, and Microsoft SQL Server, and for ORM-driven application layers built with Hibernate and SQLAlchemy. It seamlessly integrates with modern frameworks such as Django, Ruby on Rails, and FastAPI, and serves as a rock-solid backend for low-code and self-hosted platforms including Supabase, NocoDB, Appsmith, Odoo, Keycloak, Directus, Strapi, and GitLab, as well as analytical engines like ClickHouse, ensuring your database infrastructure scales without limits.
Highlights
- PostgreSQL 16 on a Hardened Base: Pre-configured with SELinux enforcing, network kernel parameter hardening, kernel module blocklists, and SSH hardening out of the box.
- Verifiable Evidence Pack and SBOM: A 7-file evidence pack ships inside the image, with tuning and security reports showing each setting against the Rocky Linux default, a CVE scan, configuration checksums, and a complete SPDX Software Bill of Materials.
- PostgreSQL 16: Best-practice deployment. Secure defaults preserved - upstream peer authentication with access bound to localhost - on an EC2-tuned base with TCP BBR and Red Hat tuned cloud profiles, rebuilt bi-weekly to monthly with upstream security patches.

Dimensions summary
You pay by the hour for the EC2 instance that runs this hardened PostgreSQL-16 image on Rocky Linux 9. Each dimension maps to one AWS instance type, so pricing scales with the size and family you pick. Smaller shared instances like t-series run lowest in hourly rate, while large, memory, compute, storage, and GPU families cost more per hour. You choose the instance that fits your workload, and your software charge accrues only while the instance runs. There is no upfront commitment; billing is purely usage-based on running hours.
Top-of-mind questions for buyers
Each hourly rate covers the hardened PostgreSQL-16 image running on Rocky Linux 9, sized to one AWS EC2 instance type. The instance type sets the CPU, memory, and storage profile you receive. The image is security-hardened following recognized benchmarks and tuned for stability.
The software charge accrues only while the instance runs. A stopped instance stops the hourly software charge. Note that underlying AWS storage for a stopped instance may still bill separately through your AWS account, independent of this software charge.
Two charges apply per running hour on the same invoice. One is this listing's software charge for the hardened PostgreSQL-16 image. The other is the standard AWS charge for the EC2 instance itself. Both scale with the instance type and the hours it runs.

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.

Usage instructions
Connection Methods
Once launched, SSH into the instance. The default username is 'rocky'. You can switch to the root user environment by running: sudo su -
Install Information
- OS: Rocky Linux 9.8
- PostgreSQL: 16
- Config File: '/var/lib/pgsql/16/data/postgresql.conf'
Usage Instructions
-
Access the database (peer authentication): This AMI uses PostgreSQL's official default peer authentication, so the 'postgres' database user has no password. Log in locally by running: sudo -u postgres psql
-
Run a query: Once inside the psql prompt, verify connectivity with: SELECT version();
-
Remote or password access (optional): By default only localhost is allowed. To enable password authentication and remote access, edit '/var/lib/pgsql/16/data/postgresql.conf' (listen_addresses) and '/var/lib/pgsql/16/data/pg_hba.conf' (authentication rules), then open port 5432 in the Security Group.
-
Manage the service: Use 'sudo systemctl start/stop/restart/status postgresql-16' to control the database service.
Firewall Configuration
-
SSH (Port 22): Required for initial system access.
-
PostgreSQL Database (Port 5432): Required for client connections to the database (localhost only by default; see step 3 to enable remote access).
-
Security Recommendation: For production environments, strictly limit access to these ports to trusted IP addresses only via cloud Security Groups or the local firewall.
