Google Professional Cloud DevOps Engineer Question 102
Select 3Google Cloud PlatformYou are managing the lifecycle of a microservices-based application deployed on Google Kubernetes Engine (GKE). The application team has decided to roll out a new version of one of the services with minimal customer impact. Which actions should you take to properly manage the deployment and service lifecycle?
- A
Use a Canary Deployment strategy to release the new version incrementally to a small subset of users.
- B
Deploy the new version immediately to all instances to ensure consistency across the environment.
- C
Set up monitoring and alerting to track the performance and errors of the new version during the rollout.
- D
Use a Blue-Green Deployment strategy to switch traffic only after validating the new version in production.
- E
Disable autoscaling temporarily on the GKE cluster to prevent unexpected scaling events during the rollout.
Show answer and explanation
Correct answers: A, C, D
Explanation
Managing the service lifecycle effectively requires careful planning of deployment strategies and monitoring. Canary and Blue-Green Deployment strategies provide controlled ways to release new versions, minimizing customer impact and allowing for quick rollbacks if needed. Monitoring and alerting are essential to ensure the system remains stable and any issues are identified promptly. Disabling autoscaling is not an advisable action during rollouts, as it could lead to resource shortages or prevent the system from responding to traffic changes effectively.
- A. Correct.
Canary Deployment is a recommended approach for managing service lifecycle updates, as it allows testing the new version with a small subset of users, reducing potential impact if issues arise.
- B. Incorrect.
Deploying the new version immediately to all instances is risky and could lead to widespread issues if the new version contains bugs or performance regressions.
- C. Correct.
Setting up monitoring and alerting is critical during a rollout to detect and address errors or performance issues in real-time.
- D. Correct.
Blue-Green Deployment is another effective strategy that allows testing the new version in production without impacting users, and it enables a quick rollback if necessary.
- E. Incorrect.
Disabling autoscaling is not recommended as it could lead to resource constraints or service instability, especially if traffic increases.
