WHAT IS VALKEY
Valkey is the open-source, high-performance Redis-compatible in-memory data store maintained by the Linux Foundation - forked from Redis OSS 7.2 in 2024 when Redis Inc. relicensed to BSL. It supports the full Redis API including strings, hashes, lists, sets, sorted sets, streams, pub/sub messaging, Lua scripting, transactions, geospatial commands, hyperloglog, bitmaps and the modules ecosystem. Operators get RDB snapshots and AOF persistence to local disk, replica replication and cluster sharding for horizontal scale. Drop-in compatible with all existing Redis clients across Java, Python, Node.js, Go, PHP, Ruby and 100+ other languages and frameworks - no application code changes required. BSD-3-Clause license - the safe vendor-neutral path forward for self-hosted Redis users.
WHAT THIS AMI ADDS
Security hardening:
Strong random password at first boot - no default or empty password
Binds to 127.0.0.1 only - not exposed to the network by default
FLUSHALL and FLUSHDB disabled
UFW firewall - port 6379 blocked externally, SSH on 22 only
fail2ban, AppArmor
OS hardening (CIS Level 1):
CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown

If you are an AWS Free Tier customer with a free plan, you are eligible to subscribe to this offer. You can use free credits to cover the cost of eligible AWS infrastructure. See AWS Free Tier for more details. If you created an AWS account before July 15th, 2025, and qualify for the Legacy AWS Free Tier, Amazon EC2 charges for Micro instances are free for up to 750 hours per month. See Legacy AWS Free Tier for more details.
You pay by the hour for the EC2 instance size you run. The six options map to standard AWS instance types. The t3 sizes (t3.micro, t3.small, t3.medium, t3.large) are burstable instances that scale from smaller to larger compute and memory. The m6i sizes (m6i.large, m6i.xlarge) offer general-purpose compute, with m6i.xlarge providing more capacity than m6i.large. You pick the size matching your workload, and hourly billing scales with the size and runtime you choose.
Top-of-mind questions for buyers
Am I charged the hourly software rate when my instance is stopped?
The software rate meters running instance-hours. A fully stopped instance stops accruing the hourly software charge. You may still pay underlying AWS fees, such as storage for the attached volume, while the instance is stopped. Billing resumes when you start the instance again.
What exactly do I get with each hourly instance option?
Each option runs the hardened Valkey image on the matching EC2 instance size. The t3 sizes are burstable general-purpose instances. The m6i sizes are fixed-performance general-purpose instances. Every image ships CIS Level 1 hardened on Ubuntu 24.04 LTS, with per-instance credentials generated at first boot.
Can I switch to a larger instance size later as my cache load grows?
Yes. Because billing meters instance-hours per size, you can stop the instance and relaunch on a larger size. Charges then follow the new size's hourly rate. There is no upfront commitment, so you only pay for the size and hours you actually run.

You can launch as many instances from as many different AMIs as you need.
Version release notes
Valkey 9.1.2
Valkey 9.1.2 on Ubuntu 24.04 LTS - security update from 9.1.1. BSD-3-Clause unchanged
Fixes GHSA-fq2f-crmw-q97r: an unauthenticated use-after-free of the Lua interpreter state, caused by a process-global script debugger command table that cached a pointer to a freed interpreter and was never invalidated
Fixes GHSA-jcj7-v34w-v9vv: a use-after-free in RDMA connection handling reachable through CLIENT KILL. This build has no RDMA listener and was not exposed to it
Closes several ACL gaps: HGETEX now requires write permission on the key, duplicate STORE options can no longer let GEORADIUS write outside permitted key patterns, MOVE and COPY check access to the destination database, and a NUL embedded in a TLS certificate CN can no longer impersonate another user
Hardens loading of untrusted data: listpacks are always validated on RDB load and RESTORE, and stream, cluster-bus and slot-import payloads are validated against crafted input
Fixes a permanent client deadlock when a blocking command is followed by a partially delivered pipelined command, a frozen monotonic clock on hosts with an unsynchronized TSC that stopped key expiration, a stack overflow when retrying a large TLS write, and AOF loss of newer writes after a short read in a MULTI block
Root volume increased from 8 GB to 10 GB for headroom above the hardened base
Rebuilt on the latest CIS Level 1 hardened Ubuntu 24.04 LTS base

Usage instructions
Launch instance (t3.small recommended)
Open Security Group - add TCP 22 from your own admin IP (for example 203.0.113.4/32). The recommended rules cover private RFC1918 ranges only; a default VPC is 172.31.0.0/16 and matches neither, so without this step you cannot reach step 4.
SSH: ssh -i key.pem ubuntu@<PUBLIC_IP>
Get password: sudo cat /root/valkey-credentials.txt
Connect on the instance: valkey-cli -a <password>
Valkey listens on 127.0.0.1:6379 and is blocked at the host firewall by default -
an in-memory cache should never listen on a public interface. To reach it from your
application servers (never from 0.0.0.0/0):
a. sudo sed -i 's/^bind 127.0.0.1 -::1/bind 0.0.0.0/' /etc/valkey/valkey.conf
sudo systemctl restart valkey
b. sudo ufw allow from 10.0.0.0/16 to any port 6379 proto tcp
c. The Security Group already permits 6379 from 10.0.0.0/16 and 10.2.0.0/16 -
narrow it to your actual subnet if it differs.
Valkey has no web console - it is a cache, driven by valkey-cli and your client
libraries. Credentials are saved to /root/valkey-credentials.txt at first boot.
