Cassandra Tutorial 3, Part 1: Modern Cassandra Deployment with Ansible - 2025 Edition

This updated tutorial reflects the significant changes in DevOps practices since our original 2017 guide:

Container-First Approach: Cassandra deployments now primarily use containers (Docker/Podman)
Kubernetes Native: StatefulSets and operators for managing Cassandra clusters
GitOps Workflows: Using ArgoCD or Flux for declarative cluster management
Modern Ansible: Ansible 2.16+ with collections and execution environments
Enhanced Security: Zero-trust networking, service mesh integration, and secrets management
Cloud Provider Integration: Native support for AWS, GCP, and Azure Kubernetes services
Observability: Built-in Prometheus metrics and distributed tracing

In this modernized tutorial, we’ll deploy a production-ready Cassandra cluster using:

Building on Part 1’s foundation, this tutorial covers:
