Overview
This guide introduces the latest versions of Cassandra, DataStax Enterprise, and OpsCenter. It shows you
how to install and set up a single-node cluster for evaluation.
You can install the cluster one of two ways:
• Using the OpsCenter GUI.
• Installing on the command line:
• Cassandra
• DataStax Enterprise
For information about setting up a production cluster, see the Cassandra or DataStax Enterprise
documentation.

Cassandra
What is Apache Cassandra?
Apache Cassandra
™
is a massively scalable open source NoSQL database. Cassandra is perfect for
managing large amounts of structured, semi-structured, and unstructured data across multiple data centers
and the cloud. Cassandra delivers continuous availability, linear scalability, and operational simplicity
across many commodity servers with no single point of failure, along with a powerful dynamic data model
designed for maximum flexibility and fast response times.
How does Cassandra work?
Cassandra sports a “masterless” architecture meaning all nodes are the same. Cassandra provides
automatic data distribution across all nodes that participate in a “ring” or database cluster. There is nothing
programmatic that a developer or administrator needs to do or code to distribute data across a cluster
because data is transparently partitioned across all nodes in a cluster.
Cassandra also provides built-in and customizable replication, which stores redundant copies of data
across nodes that participate in a Cassandra ring. This means that if any node in a cluster goes down,
one or more copies of that node’s data is available on other machines in the cluster. Replication can be
configured to work across one data center, many data centers, and multiple cloud availability zones.
Cassandra supplies linear scalability, meaning that capacity may be easily added simply by adding new
nodes online. For example, if 2 nodes can handle 100,000 transactions per second, 4 nodes will support
200,000 transactions/sec and 8 nodes will tackle 400,000 transactions/sec:

Planet Cassandra provides a 10 Minute Cassandra Walkthrough where you can download a Cassandra
virtual machine (VMware or VirtualBox). Plus you can take short video courses for developers and
administrators that demonstrate various Cassandra's features.
