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.
