Google Professional Cloud Architect Exam - Topic 3 Question 95 Discussion

Actual exam question for Google's Professional Cloud Architect exam
Question #: 95
Topic #: 3
[All Professional Cloud Architect Questions]

You are migrating third-party applications from optimized on-premises virtual machines to Google Cloud. You are unsure about the optimum CPU and memory options. The application have a consistent usage patterns across multiple weeks. You want to optimize resource usage for the lowest cost. What should you do?

Show Suggested Answer Hide Answer
Suggested Answer: A

Create a Compute engine instance with CPU and Memory options similar to your application's current on-premises virtual machine. Install the cloud monitoring agent, and deploy the third party application. Run a load with normal traffic levels on third party application and follow the Rightsizing Recommendations in the Cloud Console

Wait, why would you run high traffic tests? Isn't that risky?

I recall that option B uses App Engine, which might not be the best fit for a third-party application. I think sticking with Compute Engine is safer, like in option A.

I practiced a similar question where we had to choose between different instance types. I feel like option D could give us a better understanding of performance, but it might be overkill for cost optimization.

I'm not entirely sure, but I think option C might be too aggressive with autoscaling. We want to optimize costs, not just scale up based on CPU usage.

I remember we discussed how important it is to monitor resource usage after migration. Option A seems like a solid choice since it suggests using the cloud monitoring agent.

Option C looks interesting - using an instance template and a managed instance group to autoscale based on CPU utilization could be a good way to optimize costs. I'll make sure to understand how that works in the exam.

Hmm, I'm a bit unsure about this one. The options seem quite different, and I'm not sure which one would be the most efficient. I might need to re-read the question and think it through carefully.

Option D seems a bit overkill for this scenario. Running multiple instances with different configurations and doing a load test seems like a lot of extra work. I think I'll focus on the more straightforward options.

D could work, but running a high-traffic load test? That's like asking a hungry lion to taste-test your new recipe - not the safest option!

D) Create multiple Compute Engine instances with varying CPU and memory options. Install the cloud monitoring agent and deploy the third-party application on each of them. Run a load test with high traffic levels on the application and use the results to determine the optimal settings.

C) Create an instance template with the smallest available machine type, and use an image of the third party application taken from the current on-premises virtual machine. Create a managed instance group that uses average CPU to autoscale the number of instances in the group. Modify the average CPU utilization threshold to optimize the number of instances running.

C is an intriguing idea, but I'm not convinced autoscaling is the best approach here. What if the traffic patterns change unexpectedly?

C) Autoscaling can be risky, I agree. It's better to have more control over the resources based on the specific needs of the application.
