Simulate a canary deployment

At NovaTech, you're deploying a new version of your payments Lambda function. Use the canary traffic simulator to visualize how different deployment configurations shift traffic over time.

The simulator shows traffic distribution between the old version (blue) and new version (green) as the deployment progresses. You can select different configurations and see how canary, linear, and all-at-once deployments differ.

Experiment with triggering a simulated alarm at different points during the deployment to see how rollback works with each configuration.

Question: For a high-risk change to a payment Lambda, which strategy minimizes user impact if a bug surfaces 3 minutes into the deployment?
