This is a repackaged open source software product wherein additional charges apply for image hardening, maintenance, and support. Varnish Cache HTTP accelerator on Amazon Linux 2023, security-hardened for production: minimal package set, SSH key-only access, IMDSv2-only, per-instance admin secret, and continuously patched images.
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 Inc.
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
- Production-ready: systemd-managed Varnish on port 80 with 256 MB malloc cache; point default.vcl at your origin and restart.
- 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.

Pricing
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
Dimension | Cost/hour |
|---|---|
c7i.xlarge Recommended | $0.46 |
c7i.4xlarge | $1.84 |
c7i.2xlarge | $0.92 |
Dimensions summary
You pay by the hour for the instance size you run. The three dimensions map to compute capacity: c7i.xlarge (4 vCPU / 8 GiB), c7i.2xlarge (8 vCPU / 16 GiB), and c7i.4xlarge (16 vCPU / 32 GiB). Pricing scales with the instance size you choose, so larger instances cost more per hour. There is no subscription and no minimum. Charges stop when you terminate the instance. AWS infrastructure charges are billed separately by AWS. The software charge covers image hardening, patching, and support.
Top-of-mind questions for buyers
The charge covers image hardening, continuous patching, vulnerability scanning, and business-day support. The underlying Varnish Cache software is open source and free. You are paying for the maintained, security-hardened image and support, not the open-source software itself.
Software charges accrue only while an instance runs. Charges stop when you terminate the instance. There is no subscription and no minimum. Note that stopped instances may still incur AWS storage fees for the attached EBS volume, which AWS bills separately.
A single instance uses one EC2 instance and one gp3 EBS volume. No other AWS resources are created. AWS infrastructure charges for compute and storage are billed separately by AWS, on top of the hourly software charge shown in the pricing table.

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
[Security] Refreshed image: rebuilt on the latest hardened Amazon Linux 2023 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>. Root login is disabled; use sudo.
- Varnish listens on port 80; edit /etc/varnish/default.vcl to point the backend at your origin server, then: sudo systemctl restart varnish.
- Verify: curl -I http://<public-ip> returns a response, or: sudo systemctl status varnish.
- Sensitive data: the only secret is the per-instance varnishadm admin secret at /etc/varnish/secret (generated on first boot by varnish-firstboot.service; never shipped in the image; the admin CLI listens on localhost:6082 only). Logs under /var/log may contain client IPs - treat as personal data.
- Backup: snapshot the EBS volume (it contains all configuration and data).
- Resources: a single instance uses 1 EC2 instance and 1 gp3 EBS volume; no other AWS resources are created.
- Support: support@dcassociatesgroup.com .
