WHAT IS APACHE FLINK
Show the rest of the publisher’s description (18 more lines)
Apache Flink is an open-source framework and distributed engine for stateful computations over unbounded and bounded data streams. It runs on the JVM and is deployed here as a single-node standalone session cluster: one JobManager that schedules and coordinates work and one TaskManager that executes it, on OpenJDK 17. Flink provides event-time processing, exactly-once state consistency, checkpoints and savepoints for fault tolerance, windowing and timers, and the layered DataStream, Table and SQL APIs with pluggable source and sink connectors. This image stores checkpoints and savepoints on the local filesystem under /var/lib/flink and exposes the Flink Dashboard (Web UI) for submitting and monitoring jobs. Apache-2.0 license, no vendor lock-in. Running your own Flink keeps all job data and state inside your AWS account.
WHAT THIS AMI ADDS
Security hardening:
- A unique Basic Auth password generated at first launch for the Nginx perimeter (the Flink Dashboard has no native authentication)
- Nginx reverse proxy with TLS - the Flink Web UI proxied on port 443
- The Web UI (8081) and all internal cluster ports (JobManager RPC 6123, blob 6124, TaskManager 6121/6122) bound to localhost only - Nginx is the only exposed door
- JobManager and TaskManager run as non-root services with restricted systemd units
- Working and temporary directories placed on dedicated storage, off the hardened noexec /tmp
- 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
- auditd, SSH hardening, Kernel hardening, IMDSv2 enforced
Compliance artifacts:
- SBOM - CycloneDX 1.6 at /etc/lynxroute/sbom.json
- CIS Conformance Report at /etc/lynxroute/cis-report.html
- CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md
Highlights
Highlighted by the publisher on AWS Marketplace.
Apache Flink security baked in: a unique Basic Auth password generated at first launch, an Nginx TLS reverse proxy on 443, and the Web Dashboard plus every internal cluster port (JobManager RPC, blob, TaskManager) bound to localhost only, with working directories kept off the hardened noexec /tmp.
CIS Level 1 hardened Ubuntu 24.04 LTS: auditd, fail2ban, AppArmor, SSH key-only, IMDSv2 enforced. CVE-scanned before every release. SBOM (CycloneDX) and CIS Conformance Report included.
Stateful stream and batch processing: event-time, exactly-once state, checkpoints and savepoints, and the DataStream, Table and SQL APIs. Apache-2.0 license - fully auditable, no vendor lock-in.

Confirmed means matched to a public authoritative registry. Claimed means the vendor or its listing states it, not yet cross-checked. A framework not shown was not found in any source we hold, which is not evidence against it. Not listed means a scoped registry check found no match for this vendor's domain: a No is a scoped registry check, not a compliance judgment. Confidence bands: 95% domain-verified, 90% registry-checked, 80% self-attested, 70% weak signal. Self-attested items marked “vendor's site” are gathered from the vendor's own website and are not verified by us.

Unknown means this listing does not publish a repository. It is not a statement that the code is closed, and a linked repository is not a claim that the publisher wrote it: the registry computes that relationship privately and does not publish it.
Evidence risk is the share of the build you cannot see before you deploy, not a security rating. Sign in to see the layer-by-layer basis for this band.
