Overview Apache Cassandra is the open source distributed NoSQL database built for scalability and high availability with no single point of failure. It delivers linear scalability and proven fault tolerance across commodity hardware and cloud infrastructure, making it the database of choice for applications that need to handle very large volumes of data. This image delivers Apache Cassandra fully installed and configured, so a working database node is running within minutes of launch. The current stable line is provided.
What Is Included Apache Cassandra, installed from the official Apache Cassandra package repository, running as a single node cluster. Java 17 is installed as the runtime. The CQL shell cqlsh is preconfigured for local administration. Cassandra is the only workload on the image, so the platform stays lean and predictable.
Authentication Enabled By Default The image ships with password authentication and authorization switched on. The configuration sets the password authenticator, the Cassandra authorizer and the role based access control manager, so access to the database is controlled from the moment the node starts.
Secure First Boot On the first boot of your instance a one shot service generates a fresh, strong password for the cassandra superuser, unique to that instance, applies it to the database and writes it to a file that only the root user can read. No shared or default database credentials ship in the image.
Data On Its Own Volume Cassandra data, the commit log and saved caches live on a dedicated, independently resizable storage volume mounted at the Cassandra data directory. Database files are kept separate from the operating system disk so storage can be grown, snapshotted and backed up on its own schedule.
Ready To Use The database node, data directory and CQL shell are all configured. 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; the user guide explains how to add further nodes to build a multi node cluster.

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.
