Google Professional Cloud Developer Question 24
Select 3Google Cloud PlatformYou are tasked with modernizing an on-premises application that consists of tightly coupled components and requires minimal downtime during migration. The application needs to be containerized and deployed to Google Kubernetes Engine (GKE). Which steps should you prioritize to ensure a smooth migration and application modernization?
- A
Break the application into microservices to decouple components before containerizing it.
- B
Use Cloud Build to create container images for each application component.
- C
Deploy the application directly to a virtual machine instance in Google Compute Engine (GCE) for testing.
- D
Leverage GKE Autopilot mode to simplify cluster management and focus on application workloads.
- E
Store container images in Artifact Registry for secure and scalable storage.
Show answer and explanation
Correct answers: B, D, E
Explanation
When modernizing an application for GKE, the priority is to containerize the application efficiently and ensure it is deployed and managed in a cloud-native way. Tools like Cloud Build and Artifact Registry streamline the containerization and image management process, while GKE Autopilot mode reduces operational overhead and simplifies workload deployment. Breaking the application into microservices is a valuable step but not a priority for the initial migration when minimal downtime is required.
- A. Incorrect.
Breaking the application into microservices is an ideal long-term goal, but it is not a priority for initial containerization and migration, especially when aiming for minimal downtime. This step can be done gradually after migration.
- B. Correct.
Using Cloud Build to create container images is a key step in the modernization process. It streamlines the creation of containerized components and integrates well with other Google Cloud services.
- C. Incorrect.
Deploying the application directly to a virtual machine does not align with the goal of containerization and modernization to GKE. This would revert to legacy infrastructure practices.
- D. Correct.
GKE Autopilot mode simplifies cluster management by abstracting many operational details, allowing teams to focus on deploying and managing workloads. This is highly beneficial during modernization.
- E. Correct.
Artifact Registry is a secure and scalable solution for storing and managing container images. Using it ensures best practices for container image management and integrates seamlessly with GKE.
