Apache Cassandra on Ubuntu 24.04 LTS

Apache Cassandra is a distributed wide-column NoSQL database built for high write throughput and no single point of failure. This image gives you a production-ready deployment within minutes of first boot — no dependency wrangling, no manual hardening checklist. Published and maintained by Derek Coleman & Associates Inc: freshly rebuilt against current security advisories and deployable straight from the Azure Marketplace into your own subscription.

Get it on Azure Marketplace Deploy on Azure Support & quick start

Version: Apache Cassandra 4.1.7 (OpenJDK 11)Platform: Ubuntu 24.04 LTSPorts: 9042 (CQL native transport)Category: Databases

What's included

Apache Cassandra 4.1.7 installed from the official upstream source
Ubuntu 24.04 LTS base with automatic security updates enabled
No shared or default passwords — a unique admin credential is generated on your VM at first boot
Trusted Launch support: Secure Boot + vTPM
Azure Monitor Agent, Defender for Cloud, and Update Manager install cleanly

Quick start

Deploy from the Azure Marketplace (Get It Now → Create), choosing your SSH key at the Administration step.
Allow inbound SSH (22) for yourself plus the application port(s): 9042 (CQL) — to your application subnets only — restrict to your own IP where possible. The in-image firewall already allows them; only the Network Security Group (NSG) keeps them closed.
Connect with cqlsh using the generated superuser (see First login below), create a keyspace and your application roles.
For a multi-node cluster set seeds / listen_address in /etc/cassandra/cassandra.yaml on each node and restart.

Get your admin password (one time)

ssh <your-username>@<VM-IP>
sudo cat /var/lib/cassandra/admin-password

The default cassandra/cassandra account is disabled on this image; use the per-VM superuser in the file. Create scoped roles for applications and rotate the superuser password.

Common use cases

High-write time-series and event data
Multi-region, always-on datastores
IoT and telemetry ingestion
Product catalogs and user-activity stores

Why our images

Freshly rebuilt against the latest security advisories, no shared default credentials, Trusted Launch support, and automatic OS security updates — everything runs in your own Azure subscription under your governance.
