Overview
Apache Cassandra is the open source distributed NoSQL database built for scalability and high availability with no single point of failure. This AMI delivers a fully configured, security-hardened Cassandra node that accepts CQL queries within minutes of launch - eliminating the hours of manual installation, Java configuration, and authentication setup required by a bare install.
Why This Image Over Alternatives
Unlike many community Cassandra AMIs that ship with authentication disabled and default credentials, this image enforces password authentication and role-based access control from the first boot. Where self-managed installs co-locate database files on the OS disk - complicating backups and risking disk contention - this image isolates all Cassandra data on a dedicated, independently resizable EBS volume. The result is a lean, single-workload instance with predictable latency and straightforward operational management.
What Is Included
- Apache Cassandra installed from the official Apache package repository, running as a single-node cluster
- Java 17 runtime
- CQL shell (cqlsh) preconfigured for local administration
- Dedicated data volume for commit logs, SSTables, and saved caches
- Password authenticator, Cassandra authorizer, and RBAC enabled by default
Secure First Boot
On first boot a one-shot service generates a cryptographically strong password for the cassandra superuser, unique to that instance, applies it to the database, and writes it to a file readable only by root. No shared or default database credentials ever exist in the image.
AWS Integration Points
- Amazon EBS - Cassandra data lives on a dedicated EBS volume; use EBS Snapshots for point-in-time backups or resize storage independently of the OS disk.
- Amazon VPC - Deploy nodes within private subnets and control access with security groups (port 9042 for CQL native transport, port 7000 for inter-node communication).
- Amazon CloudWatch - Forward Cassandra JMX metrics and system logs to CloudWatch for centralized monitoring and alerting.
- AWS Backup - Schedule automated, policy-driven backups of the data volume without custom scripting.
Ready To Use
Connect over SSH, read the generated superuser password, and open cqlsh to create keyspaces and tables. The node runs as a single-node cluster by default; expand to a multi-node cluster by updating seed addresses and replication settings in cassandra.yaml.
Use Cases
- IoT and time-series ingestion - Handle millions of sensor writes per second across commodity instances for industrial telemetry or fleet tracking.
- Always-on web and mobile backends - Serve user profiles, session state, and preferences with tunable consistency and no single point of failure.
- Product catalogs and personalization - Store and retrieve large, sparse datasets for e-commerce recommendations at low latency.
- Messaging and activity feeds - Power high-throughput append workloads for social feeds, notifications, and audit logs.

Highlights
- Security hardened from first boot - unlike many Cassandra AMIs that ship wide-open, this image enables password authentication, role-based authorization, and generates a unique superuser credential per instance automatically. No default or shared passwords ever exist, giving you a locked-down database node without manual hardening steps.
- Production-ready in minutes, not hours - Apache Cassandra, Java 17, and the cqlsh shell are preinstalled and configured as a single-node cluster. Skip the manual package installation, Java setup, and configuration editing that a bare install demands. Expand to a multi-node cluster by updating seed addresses in cassandra.yaml.
- Dedicated data volume and 24/7 expert support - Cassandra data, commit logs, and caches live on a separate EBS volume you can resize, snapshot, and back up independently of the OS disk. cloudimg engineers provide round-the-clock support by email and chat with a one-hour average response for critical issues, covering deployment, cluster expansion, data modeling, and performance tuning.

64-bit (x86) Amazon Machine Image (AMI)
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
Initial release of the Apache Cassandra image.
Additional details
Usage instructions
Connect via SSH on port 22 as the default login user for your operating system variant (the user guide lists it per variant). Apache Cassandra listens for CQL on 127.0.0.1 port 9042 on the instance itself. Retrieve the generated superuser password with: sudo cat /root/cassandra-credentials.txt. Open the CQL shell with: cqlsh-cloudimg -u cassandra -p <password>. Use nodetool status to confirm the node is up. The user guide explains how to create keyspaces and tables and how to add further nodes for a multi node cluster.

How to Get Help
Contact the support team at support@cloudimg.co.uk . Include your instance ID, region, and a description of the issue or question. For refund requests, email the same address with your AWS Marketplace subscription details.
Recommended Instance Sizing
For evaluation and development workloads, a t3.medium or m5.large with a 50 GB gp3 data volume is sufficient. For production workloads with sustained write throughput, consider i3 or i3en instances with local NVMe storage or provision larger gp3/io2 volumes sized to your dataset. Open a support ticket for personalized sizing guidance based on your expected data volume and query patterns.
