This is a repackaged open source software product wherein additional charges apply for hardening, security configuration, and setup support.
Grafana Loki is a single-binary, horizontally-scalable log aggregation system queried with LogQL, run here monolithic on a single node with filesystem storage. This Lynxroute build is hardened and ready out of the box: a unique Basic Auth password generated at first launch, an Nginx TLS reverse proxy on 443, the Loki API and gRPC bound to localhost only, usage analytics disabled, UFW firewall pre-configured, and a CIS Level 1 hardened Ubuntu 24.04 LTS base.
AGPL-3.0 license - fully auditable, no vendor lock-in.

WHAT IS GRAFANA LOKI
Grafana Loki is a horizontally-scalable, multi-tenant log aggregation system, shipped as a single statically linked Go binary and run here in monolithic mode on one node. Instead of indexing the full text of every log line, Loki indexes only a small set of labels and stores compressed log chunks, which keeps storage and cost low. It exposes an HTTP API: push logs in (Promtail, Grafana Alloy, the Docker logging driver, Fluentd or Fluent Bit) and query them back with LogQL, Loki's label-and-filter query language. This image stores chunks and the TSDB index on the local filesystem under /var/lib/loki, with retention and compaction enabled. Loki has no web UI of its own; you query it through Grafana (it pairs with the Lynxroute Grafana image as a data source), logcli, or curl. AGPL-3.0 license, no vendor lock-in. Running your own Loki keeps all log data inside your AWS account.
WHAT THIS AMI ADDS
Security hardening:
A unique Basic Auth password generated at first launch for the Nginx perimeter (Loki has no native auth)
Nginx reverse proxy with TLS - the Loki API proxied on port 443
Loki HTTP API (3100) and gRPC (9096) bound to localhost only - Nginx is the only exposed door
Usage analytics disabled (no phone-home to the upstream telemetry endpoint)
Loki runs as a non-root service with a restricted systemd unit
UFW firewall - ports 22, 80, 443 only
fail2ban, AppArmor
CVE scan - every image is scanned for vulnerabilities before release
OS hardening (CIS Level 1):
CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown
CIS Conformance Report at /etc/lynxroute/cis-report.html
CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md
Highlights
Loki security baked in: a unique Basic Auth password generated at first launch, an Nginx TLS reverse proxy on 443, the Loki API and gRPC bound to localhost only, and usage analytics disabled.
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.
Try this product free for 5 days according to the free trial terms set by the vendor. Usage-based pricing is in effect for usage beyond the free trial terms. Your free trial gets automatically converted to a paid subscription when the trial ends, but may be canceled any time before that.
You pay by the hour based on the EC2 instance size you choose to run this hardened log aggregation image. The five options map to different compute capacities. The t3.small, t3.medium, and t3.large are burstable instances suited to lighter or variable workloads. The m6i.large and m6i.xlarge are general-purpose instances for steadier or heavier processing. Pricing scales with the instance you select, so cost rises with more compute. Each option runs the same image, so you pick the size that fits your workload rather than a feature tier.
Top-of-mind questions for buyers
What compute specs come with each hourly instance option?
Each option maps to a standard AWS EC2 instance type. The t3.small, t3.medium, and t3.large are burstable instances with rising CPU and memory. The m6i.large and m6i.xlarge are general-purpose instances with fixed performance and larger memory. You choose based on your log volume and processing needs.
Am I charged when the instance is stopped or paused?
The hourly software fee meters running time. A fully stopped instance does not accrue the hourly software charge. Underlying AWS storage costs for the attached volumes may still apply while stopped. Charges resume once you start the instance again.
Does the hourly price include the underlying AWS infrastructure cost?
The hourly rate covers the hardened software image. AWS charges separately for the EC2 instance, storage, and data transfer used to run it. Your total cost combines the software hourly fee with the standard AWS resource charges for the instance size you select.

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
Grafana Loki 3.7.7
Grafana Loki 3.7.7 on Ubuntu 24.04 LTS - patch update from 3.7.6. AGPL-3.0 unchanged
Open https://<PUBLIC_IP> in your browser - accept the self-signed certificate warning, sign in with the Basic Auth user and the generated password; you will see the Loki API info page
Add Loki to Grafana: data source type Loki, URL https://<PUBLIC_IP>/, Basic Auth on (user admin + the generated password), TLS skip-verify until you install a CA certificate
Ship logs to https://<PUBLIC_IP>/loki/api/v1/push (Promtail, Grafana Alloy, the Docker loki driver) and query with LogQL
Loki has no web UI of its own - it is a LogQL API backend queried through Grafana, logcli, or curl.
The Basic Auth password is generated uniquely at first launch.
Credentials are saved to /root/loki-credentials.txt at first boot.
Logs are stored on the local filesystem under /var/lib/loki with retention and compaction enabled.
Replace the self-signed TLS certificate with a CA-signed certificate (sudo certbot --nginx) for production use.
