SAMPLE QUESTION:

You recently deployed your application on Google Kubernetes Engine (GKE) and now need to release a new version of the application. You need the ability to instantly roll back to the previous version of the application in case there are issues with the new version.

Which deployment model should you use?

• A. Perform a rolling deployment, and test your new application after the deployment is complete.
• B. Perform A/B testing, and test your application periodically after the deployment is complete.
• C. Perform a canary deployment, and test your new application periodically after the new version is deployed.
• D. Perform a blue/green deployment, and test your new application after the deployment is complete.

Explanation

Incorrect Answers:

A. Perform a rolling deployment, and test your new application after the deployment is complete.

Involves gradually updating pods with the new version of the application, replacing the old version incrementally. This method minimizes downtime, as the service remains available during the deployment. However, if issues arise with the new version, rolling back is not instant and can be complex. The process would involve reversing the rollout, which is time-consuming and may not be suitable for scenarios where immediate fallback is crucial.

B. Perform A/B testing, and test your application periodically after the deployment is complete.

Is a strategy where two or more versions of the application are deployed simultaneously, and traffic is split between them. This model is typically used for testing user response to new features or changes. It’s more about gathering data and insights rather than quick rollback capabilities. In case of any issues with the new version, an immediate switch back to the old version isn’t the primary focus of A/B testing, making it less ideal for situations requiring rapid response to deployment problems.

C. Perform a canary deployment, and test your new application periodically after the new version is deployed.

Sees the new version released to a small subset of users first. If this initial release proves successful, the new version is then rolled out to the entire user base. The advantage of this approach is that it reduces the risk of a faulty update affecting all users at once, as any problems can be identified and fixed during the initial, smaller release. However, like A/B testing, canary deployments don’t emphasize instant rollback. If the new version encounters issues, rolling back to the old version across the entire user base would not be as immediate as needed.

Correct answer:

D. Perform a blue/green deployment, and test your new application after the deployment is complete.

Operates with two identical environments, one running the current (blue) version and the other the new (green) version of the application. After deploying the green version, traffic is switched over from blue to green. If the new version encounters any problems, traffic can be instantly reverted back to the blue environment. This approach greatly minimizes downtime and risk, as the old version remains operational and can be quickly reinstated if necessary. The primary downside is the need for double the resources, as both environments run concurrently. Despite this, the level of control and safety it offers, especially for instant rollbacks, often justifies the additional resource requirement.
