AWS Cassandra Cluster Tutorial 5 (2025): Modern Cassandra Deployment with CDK, EKS, and Infrastructure as Code

Cassandra Cluster Tutorial 5 (2025) - Modern AWS Cassandra Deployment with CDK, EKS, and Infrastructure as Code

This Cassandra tutorial is designed for developers and DevOps/SRE teams who want to deploy production-ready Cassandra clusters in AWS using modern practices and tools available in 2025.

What’s New in 2025

The landscape of deploying Cassandra on AWS has evolved significantly:

1. AWS CDK v2 has become the standard for infrastructure as code, offering type-safe infrastructure definitions
2. Kubernetes operators like K8ssandra provide production-ready Cassandra deployments
3. AWS Graviton3 processors offer 40% better price-performance for Cassandra workloads
4. Container-based deployments are now the norm, with EKS Anywhere for hybrid deployments
5. Service mesh integration with AWS App Mesh provides advanced traffic management
6. AWS Systems Manager replaces bastion hosts for secure access
7. GitOps workflows with AWS CodeCommit and FluxCD for infrastructure management

Cloudurable provides Cassandra training, Cassandra consulting, Cassandra support and helps setting up Cassandra clusters in AWS.

AWS Cassandra Cluster Tutorial 5: Setting up Cassandra Cluster in AWS/EC2

Cassandra Cluster Tutorial 5 - Cassandra AWS Cluster with CloudFormation, bastion host, Ansible and the aws-command line

This Cassandra tutorial is useful for developers and DevOps/DBA staff who want to launch a Cassandra cluster in AWS.

The cassandra-image project has been using Vagrant and Ansible to set up a Cassandra Cluster for local testing. Then we used Packer, Ansible and EC2. We used Packer to create AWS images in the last tutorial. In this tutorial, we will use CloudFormation to create a VPC, Subnets, security groups and more to launch a Cassandra cluster in EC2 using the AWS AMI image we created with Packer in the last article. The next two tutorials after this one, will set up Cassandra to work in multiple AZs and multiple regions using custom snitches for Cassandra.
