Zero-Downtime Blue-Green AWS Deployments with Route 53
Stop just reading about cloud architecture and start building it. This hands-on, project-based tutorial guides you step-by-step from an empty folder to a production-grade, highly available web application on AWS, all defined in TypeScript using the AWS Cloud Development Kit (CDK).
You won't just build a single server. You'll learn to think like a cloud architect by building a multi-stack CDK project that correctly separates your network, your stateful database (RDS), and your stateless application (EC2/ASG). This structure is the foundation for all serious cloud-native applications.
The core of this tutorial is mastering Blue/Green deployments. You will:
- Deploy a "Blue" (v1.0) version of a Node.js app.
- Deploy a "Green" (v2.0) version in parallel.
- Use Amazon Route 53 to perform a real-time canary release, shifting a small percentage of live traffic to your new version.
- Execute a full traffic cutover and, most importantly, simulate a failure and perform an instant rollback with zero downtime.
By the end, you won't just have a course completed; you'll have a working project, a deep understanding of modern deployment strategies, and the confidence to build and manage resilient, scalable applications on AWS.
