How do I implement canary releases for Robust Perception basics?

Canary releases are a powerful technique for deploying new features or updates to a small subset of users before a full rollout. This method allows teams to monitor the performance and stability of the new version, minimizing risks and gathering valuable feedback.

To implement canary releases for Robust Perception basics, follow these steps:

  • Step 1: Select a small percentage of your user base for the canary deployment.
  • Step 2: Deploy the new version to this group while keeping the majority on the stable version.
  • Step 3: Monitor key metrics such as error rates, performance, and user feedback.
  • Step 4: If the canary release performs well, gradually increase the percentage of users receiving the update.
  • Step 5: Roll back quickly if any critical issues arise during the canary phase.

Here’s a simplified example of how to implement a canary release in PHP:

<?php $allUsers = getAllUsers(); $canaryUsers = array_filter($allUsers, function ($user) { return rand(0, 100) <= 10; // 10% for canary }); if (in_array($currentUser, $canaryUsers)) { // Deploy new feature deployNewFeatureFor($currentUser); } else { // Deploy stable version deployStableVersionFor($currentUser); } ?>
