Exam Professional Cloud Developer topic 1 question 174 discussion

Actual exam question from Google's Professional Cloud Developer
Question #: 174
Topic #: 1
[All Professional Cloud Developer Questions]

You need to migrate a standalone Java application running in an on-premises Linux virtual machine (VM) to Google Cloud in a cost-effective manner. You decide not to take the lift-and-shift approach, and instead you plan to modernize the application by converting it to a container. How should you accomplish this task?

  • A. Use Migrate for Anthos to migrate the VM to your Google Kubernetes Engine (GKE) cluster as a container.
  • B. Export the VM as a raw disk and import it as an image. Create a Compute Engine instance from the Imported image.
  • C. Use Migrate for Compute Engine to migrate the VM to a Compute Engine instance, and use Cloud Build to convert it to a container.
  • D. Use Jib to build a Docker image from your source code, and upload it to Artifact Registry. Deploy the application in a GKE cluster, and test the application.

Jib is a tool that builds Docker images from Java code without the need for a Dockerfile. This makes it easy to containerize Java applications, even if you don't have any experience with Docker.

This seems to be exactly the situation described in this tutorial: https://cloud.google.com/migrate/containers/docs/migrating-monolith-vm-overview-setup So I think that option A is correct

Indeed, but I think Alt A doesn't address the whole picture. Migrate for Anthos itself would not automatically containerize the Java app running on the Linux VM. Migrate for Anthos can package the VM as a Kubernetes pod, but the application within the VM remains unchanged in its original form. To containerize this application and make it fully compatible with GKE, additional steps - those described in Alt D - would be required. Alternative D is correct.
