Apache Cassandra on AWS

Enterprise-level reliability, security, and management

This Partner Solution is for users who want to deploy an Apache Cassandra cluster to the Amazon Web Services (AWS) Cloud for development or testing purposes. Cassandra steamlines operations and controlling costs for workloads.

This Partner Solution includes AWS CloudFormation templates and a guide that provides step-by-step instructions to help you get the most out of your deployment.

This Partner Solution was developed by DataStax in collaboration with AWS. DataStax is an AWS Partner.

AWS Service Catalog administrators can add this architecture to their own catalog.  

  •  What you'll build
  • This Partner Solution sets up the following:

    • A highly available architecture that spans three Availability Zones.*
    • A virtual private network (VPN) configured with public and private subnets, according to AWS best practices, to provide you with your own virtual network on AWS.*
    • In the public subnets:
      • Managed network address translation (NAT) gateways to allow outbound internet access for resources in the private subnets.
      • A DevOps instance where you can use tools to help manage the cluster.
    • In the private subnets:
      • Amazon Elastic Compute Cloud (Amazon EC2) seed nodes used to bootstrap the gossip process for new nodes joining a cluster. These nodes are the inital Amazon EC2 instances that are outside of the Amazon EC2 Auto Scaling group that assists in bootstraping the cluster.
      • Cassandra non-seed nodes (starting with the fourth node onwards) that are part of the Amazon EC2 Auto Scaling group. 
      • Amazon EC2 Auto Scaling group used for scaling Cassandra nodes in the private subnets based on workload demand.
    • An Amazon Simple Storage Service (Amazon S3) bucket for storing the AWS CloudFormation templates and scripts.

    * The template that deploys the Partner Solution into an existing VPC skips the components marked by asterisks and prompts you for your existing VPC configuration.

  •  How to deploy
  • To deploy this Partner Solution, follow the instructions in the deployment guide, which includes these steps.

    1. If you don't already have an AWS account, sign up at, and sign in to your account.

    3. Test the deployment.

    Amazon may share user-deployment information with the AWS Partner that collaborated with AWS on this solution.  

  •  Costs and licenses
  • This Partner Solution includes Apache Cassandra 4.0.

    You are responsible for the cost of the AWS services and any third-party licenses used while running this solution. There is no additional cost for using the solution.

    This solution includes configuration parameters that you can customize. Some of these settings, such as instance type, affect the cost of deployment. For cost estimates, refer to the pricing pages for each AWS service you use. Prices are subject to change.

    Tip: After you deploy a solution, create AWS Cost and Usage Reports to track associated costs. These reports deliver billing metrics to an Amazon Simple Storage Service (Amazon S3) bucket in your account. They provide cost estimates based on usage throughout each month and aggregate the data at the end of the month. For more information, refer to What are AWS Cost and Usage Reports?
