etcd distributed key-value store on Amazon Linux 2023, security-hardened for production: minimal package set, SSH key-only access, IMDSv2-only, client API bound to loopback until you configure TLS, and continuously patched images. This product has charges associated with it for image hardening, maintenance, and support.
etcd (Hardened) on Amazon Linux 2023 is a production-ready, security-hardened image of the etcd distributed, consistent key-value store, maintained and supported by Derek Coleman & Associates Inc.
This is repackaged open-source software. etcd is a Cloud Native Computing Foundation graduated project distributed under the Apache License 2.0. This product bundles unmodified upstream etcd 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 the etcd client API bound to 127.0.0.1:2379 (configuring TLS certificates, peer URLs, and cluster membership, then opening 2379/2380 to trusted CIDRs, is a deliberate customer step before any remote or cluster use). Images are rebuilt, scanned for HIGH and CRITICAL vulnerabilities, and republished on a regular cadence so that new launches start current. Manage the service with systemd: sudo systemctl restart etcd.
Highlights
Production-ready: systemd-managed etcd with etcdctl and etcdutl included; single-member out of the box, cluster-ready.
Security-hardened at build time: minimal packages, key-only SSH, IMDSv2-only, client API on loopback until you configure TLS.
Continuously patched: rebuilt, vulnerability-scanned, and republished on a regular cadence.
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
You pay by the hour based on the EC2 instance size you choose. All three options run the same hardened etcd image on Amazon Linux 2023. They differ only in compute capacity. The c7i.xlarge gives you the smallest vCPU and memory allotment. The c7i.2xlarge doubles that capacity, and the c7i.4xlarge doubles it again. Pick the size that matches your workload; the hourly rate rises with the instance size. Billing is usage-based and metered through AWS on your existing cloud invoice. It runs in your own AWS account under your controls.
Top-of-mind questions for buyers
What compute do I get with each c7i instance size?
Each option maps to a fixed vCPU and memory pairing. The c7i.xlarge is the smallest allotment. The c7i.2xlarge doubles that capacity, and the c7i.4xlarge doubles it again. All run the same single-node, loopback-only hardened etcd image on Amazon Linux 2023.
Am I charged when the instance is stopped or paused?
The software meters running hours only. Fully stopped instances stop accruing software charges. Stopped instances may still incur underlying AWS storage fees for the attached disk, but those are separate from the per-hour software charge billed on your cloud invoice.
How does the per-hour software charge relate to the vCPU count?
Software pricing is metered per vCPU per hour and billed by your cloud provider. Larger instances carry more vCPUs, so the hourly software charge rises with instance size. The charge appears on your existing cloud invoice with no separate vendor billing relationship.

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.
