Overview
Varnish Cache (Hardened) on Amazon Linux 2023 is a production-ready, security-hardened image of the Varnish Cache HTTP accelerator, maintained and supported by Derek Coleman & Associates Incorporated.
This is repackaged open-source software. Varnish Cache is developed by the Varnish Cache project and is distributed under a BSD 2-Clause license. Varnish is a trademark of Varnish Software AB; this listing is not endorsed by or affiliated with Varnish Software. This product bundles unmodified upstream Varnish Cache 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, the varnishadm management secret generated per instance on first boot (never baked into the image), admin interface bound to localhost, host firewall exposing only the HTTP port, and no default credentials anywhere. Images are rebuilt, scanned for HIGH and CRITICAL vulnerabilities, and republished on a regular cadence so that new launches start current. Varnish listens on port 80 with the backend defined in /etc/varnish/default.vcl (placeholder points at 127.0.0.1:8080 until you configure your origin).
Highlights
- Security-hardened at build time: minimal packages, key-only SSH, IMDSv2-only, per-instance admin secret, admin interface on localhost only.
- Continuously patched: rebuilt, vulnerability-scanned, and republished on a regular cadence.
- Production-ready: systemd-managed Varnish on port 80 with 256 MB malloc cache; point default.vcl at your origin and restart.

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.
