ECS/EKS Service Deployment
Deploy a service to a mock EKS cluster, roll out a new version and roll back when health checks fail.
🎯 You will learn to
- Run a rolling update
- Use health checks
- Roll back
🧪 Live environment
Runs entirely in your browser: nothing is installed, no real cloud account is used and your code is never sent to our server.

✅ Steps & checkpoints
🗺️ Rolling update with rollback
New pods replace old ones a few at a time; failing health checks stop the rollout and roll back to the last good version.
The 2D diagram shows the exact flow, ports and trust boundaries. The 3D scene is a concept view of the same parts; packets travel along the same arrows.
🤔 Think about it
What is the difference between a rolling and a blue/green deploy?
🛡️ Safety & cost
Mock mode by default. Real AWS practice is opt-in: use a sandbox account, AWS Budgets and least-privilege roles.
🧹 Cleanup
Delete the CloudFormation stack and check Cost Explorer the next day.
