This product has charges associated with it for hardening, security configuration, and support.
Apache Cassandra is the open-source, distributed NoSQL wide-column database (Apache Software Foundation), running here as a single-node JVM service on Eclipse Temurin 17. Unlike bare Cassandra AMIs that ship the default cassandra/cassandra superuser, no authentication, no encryption, and an exposed JMX port, this Lynxroute build is security baked in: the default superuser password is rotated to a strong random value at first boot, password authentication and authorization are enabled, native TLS (client encryption) is required on port 9042, CQL and JMX bind to localhost only, UFW firewall pre-configured, and a CIS Level 1 hardened Ubuntu 24.04 LTS base.
Apache-2.0 license - fully auditable, no vendor lock-in.
Overview
This is a repackaged software product wherein additional charges apply for hardening, security configuration, and support.
WHAT IS APACHE CASSANDRA
Apache Cassandra is an open-source, distributed NoSQL wide-column database built for high availability and linear scalability with no single point of failure. It runs as a JVM service (Eclipse Temurin 17) and is queried with CQL (Cassandra Query Language) over a native binary protocol on port 9042. Cassandra offers tunable consistency, a masterless peer-to-peer architecture, partitioned wide-column data model with clustering keys, secondary indexes, materialized views, lightweight transactions (Paxos), TTL on data, and time-to-live driven compaction. Data is durably persisted to local disk as SSTables with a commit log, hints, and saved caches. CQL drivers exist for Java, Python, Node.js, Go, C#, and many more. This image ships a single-node deployment, ready to scale into a cluster. Apache-2.0 license - the vendor-neutral upstream distribution, distinct from any commercial Cassandra product.
WHAT THIS AMI ADDS
Security hardening:
- Default cassandra/cassandra superuser password rotated to a strong random value at first boot
- PasswordAuthenticator and CassandraAuthorizer enabled - no anonymous access
- Native TLS (client encryption) required on port 9042; self-signed certificate generated per instance at first boot
- CQL (9042) and JMX (7199) bind to 127.0.0.1 only - not exposed to the network by default
- UFW firewall - only SSH (22) open; 9042 blocked externally
- 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
- Cassandra security baked in: default superuser password rotated at first boot, password auth + authorization enabled, native TLS required on 9042, CQL and JMX bound to localhost.
- 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.
- Distributed NoSQL wide-column database: CQL, tunable consistency, masterless scale-out, single-node ready to cluster. Apache-2.0 license - fully auditable, no vendor lock-in.

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.
Dimension | Cost/hour |
|---|---|
t3.medium Recommended | $0.05 |
m6i.large | $0.05 |
m6i.xlarge | $0.05 |
t3.large | $0.05 |
t3.small | $0.03 |
Dimensions summary
You pay by the hour for a hardened Cassandra NoSQL database image, billed based on the EC2 instance size you run. Five instance sizes are available. The t3.small, t3.medium, and t3.large are burstable options that step up in capacity. The m6i.large and m6i.xlarge are general-purpose options, with the xlarge providing more compute than the large. Pricing scales with the instance you choose, so you match capacity to your workload. The same hardened, compliant image ships across all five sizes, so the difference is compute capacity, not features.
Top-of-mind questions for buyers
Each name is an AWS EC2 instance size. You pay the software rate for each hour that size runs. The burstable t3 sizes step up from small to large. The m6i sizes are general-purpose, with xlarge offering more compute than large. You match the size to your workload.
The software charge meters running hours. A fully stopped instance does not accrue the hourly software fee. Note that underlying AWS storage and other resource fees may still apply while the instance is stopped, billed separately by AWS.
Only more compute. The same hardened, compliant Cassandra image ships across all five sizes. Each includes CIS Level 1 hardening, CVE scanning, a bundled software bill of materials, and per-instance credentials generated at first boot. Choosing a size changes capacity, not what is inside.

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
Apache Cassandra 5.0.9 - bugfix release. Fixes coordinator load-shedding returning OverloadedException without a streamId, which misrouted query responses (CASSANDRA-21508); makes SAI component checksum validation segment-aware (CASSANDRA-21516); corrects an AssertionError in hasReplicaWithOngoingRepair when parallel_repair_count is greater than 1 (CASSANDRA-21426); uses estimated compressed table size when checking free space for a compaction (CASSANDRA-21245); and ensures SAI sends range tombstones to the coordinator for queries on static columns (CASSANDRA-21332). cqlsh now supports Python 3.12 and 3.13 (CASSANDRA-20997). Also carries backported 4.0 fixes for BTree.FastBuilder state that could corrupt SSTable headers during schema disagreement (CASSANDRA-21216, CASSANDRA-21260), snapshot name validation (CASSANDRA-21389), and PasswordObfuscator failing to obfuscate certain passwords (CASSANDRA-21113). Rebuilt on the latest CIS Level 1 hardened Ubuntu 24.04 LTS base.
Additional details
Usage instructions
- Launch instance (t3.medium recommended; t3.small minimum)
- SSH: ssh -i key.pem ubuntu@<PUBLIC_IP>
- Read credentials: sudo cat /root/cassandra-credentials.txt
- Connect with cqlsh over TLS using the generated superuser password: cqlsh --ssl -u cassandra -p '<password>' (a system /etc/cassandra/cqlshrc is preconfigured for TLS, so cqlsh --ssl works as-is)
- Run CQL, e.g.: CREATE KEYSPACE demo WITH replication = {'class':'SimpleStrategy','replication_factor':1};
- Cluster admin: nodetool status
The default cassandra superuser password is rotated to a strong random value at first boot and written to /root/cassandra-credentials.txt. Native TLS (client encryption) is required on port 9042; a self-signed certificate is generated per instance.
CQL (9042) and JMX (7199) bind to 127.0.0.1 only. To allow remote clients, set rpc_address/broadcast_rpc_address in /opt/cassandra/conf/cassandra.yaml, open TCP 9042 in the Security Group to your client CIDR, and restart: sudo systemctl restart cassandra.
For production, replace the self-signed keystore with your own CA-signed certificate (update client_encryption_options in cassandra.yaml) and restart the service.
