Google Professional Cloud DevOps Engineer Question 101
Select 3Google Cloud PlatformYour team is managing the lifecycle of a microservice running on Google Kubernetes Engine (GKE). The service is currently in the production phase, but you are planning a major feature rollout. To ensure availability and smooth deployment, you decide to use a phased release strategy. Which actions should you prioritize as part of managing the service lifecycle for this scenario?
- A
Use a canary deployment to test the new feature with a small subset of users before rolling it out to all users.
- B
Perform a full cluster upgrade on GKE before deploying any changes to ensure all dependencies are updated.
- C
Implement monitoring and alerting to track key performance metrics and errors during the rollout.
- D
Roll back any previous versions of the service to simplify the deployment process.
- E
Define clear service level objectives (SLOs) to measure the impact of the new feature on user experience.
Show answer and explanation
Correct answers: A, C, E
Explanation
Managing the service lifecycle during a major feature rollout requires careful planning and execution. Canary deployments minimize risk, monitoring ensures issues are quickly identified, and SLOs provide a framework for understanding the service's impact on users. These practices align with DevOps principles and help maintain high availability and reliability during the rollout.
- A. Correct.
Using a canary deployment allows you to gradually test the new feature with a limited audience while minimizing risk to the entire user base. This is a key practice in managing service lifecycles during feature rollouts.
- B. Incorrect.
Performing a full cluster upgrade on GKE is not directly related to this scenario and could introduce additional risks or downtime. Cluster upgrades should be planned and tested independently from feature rollouts.
- C. Correct.
Implementing monitoring and alerting ensures that you can track the behavior of the system during the deployment and respond to any issues that arise. This is crucial for maintaining service availability throughout the lifecycle.
- D. Incorrect.
Rolling back previous versions of the service is unnecessary in this scenario and could disrupt the system. Instead, focus on deploying the new feature in a controlled manner.
- E. Correct.
Defining clear SLOs ensures you can measure the impact of the new feature on the user experience, helping you manage the service lifecycle effectively and make data-driven decisions.
