This product has charges associated with it for image hardening, maintenance, and support. Memcached on Amazon Linux 2023, security-hardened for production: minimal package set, SSH key-only access, IMDSv2-only, bound to loopback with UDP disabled (no amplification vector), and continuously patched images.
Overview
Memcached (Hardened) on Amazon Linux 2023 is a production-ready, security-hardened image of the Memcached distributed memory object caching system, maintained and supported by Derek Coleman & Associates Incorporated.
This is repackaged open-source software. Memcached is developed by the Memcached community and is distributed under the BSD 3-Clause license. This product bundles unmodified upstream Memcached 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, Memcached bound to 127.0.0.1 with UDP disabled so the instance cannot be used as an amplification vector. Widening the bind address in /etc/sysconfig/memcached and opening TCP 11211 to trusted CIDRs is a deliberate customer configuration step. 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 memcached.
Highlights
- Security-hardened at build time: minimal packages, key-only SSH, IMDSv2-only, bound to loopback, UDP disabled to prevent amplification abuse.
- Continuously patched: rebuilt, vulnerability-scanned, and republished on a regular cadence.
- Production-ready: systemd-managed Memcached; expose only to trusted CIDRs after you widen the bind.

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.

c7i.xlarge Recommended | $0.46 |
c7i.4xlarge | $1.84 |
c7i.2xlarge | $0.92 |
Dimensions summary
You pay by the hour for a hardened Memcached image running on Amazon Linux 2023. Pricing is metered per hour based on the EC2 instance size you choose. Three compute sizes are available: c7i.xlarge, c7i.2xlarge, and c7i.4xlarge. These are not feature tiers. They differ only in compute capacity, so you select the size that matches your workload. Larger instances carry a higher hourly rate. Software charges are metered and billed by AWS on your existing cloud invoice, alongside the standard EC2 infrastructure cost for the instance you run.
Top-of-mind questions for buyers
Each size maps to a fixed vCPU and memory allocation. The c7i.xlarge is the smallest of the three, the c7i.2xlarge doubles that capacity, and the c7i.4xlarge doubles it again. You pick the size that fits your cache workload. All three run the same hardened Memcached image.
Software charges meter per running instance-hour. A stopped instance accrues no hourly software charge. You may still pay AWS for attached storage while the instance is stopped, but the Memcached software license meters running time only.
Two charges apply together on the same AWS invoice. The software fee meters per hour at the rate for your chosen instance size. Separately, AWS bills the standard EC2 compute cost for that instance. Both accrue only while the instance runs, and no separate vendor billing relationship is needed.

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.

Usage instructions
Launch from AWS Marketplace (1-Click or EC2 console). Connect via SSH: ssh -i <key> ec2-user@<public-ip>. Memcached binds to 127.0.0.1 with UDP off. To expose it, edit /etc/sysconfig/memcached (-l), then: sudo systemctl restart memcached, and open TCP 11211 to trusted CIDRs only. Root login is disabled; use sudo. There are no passwords anywhere in this product.
