Actual exam question for Google's Professional Cloud Developer exam

Question #: 107
Topic #: 9

[All Professional Cloud Developer Questions]

You are developing a single-player mobile game backend that has unpredictable traffic patterns as users interact with the game throughout the day and night. You want to optimize costs by ensuring that you have enough resources to handle requests, but minimize over-provisioning. You also want the system to handle traffic spikes efficiently. Which compute platform should you use?

ACloud Run

BCompute Engine with managed instance groups

CCompute Engine with unmanaged instance groups

DGoogle Kubernetes Engine using cluster autoscaling

Wait, can Cloud Run really handle those spikes?

I’m leaning towards Compute Engine with managed instance groups, but I’m worried about the complexity of managing instances compared to something like Cloud Run.

I feel like Google Kubernetes Engine could be a strong contender too, especially with cluster autoscaling. But I need to double-check if it's overkill for a single-player game backend.

I remember practicing with managed instance groups before, and they seem like a solid option for handling unpredictable traffic. I just hope I don't confuse it with unmanaged groups during the exam.

I think Cloud Run might be a good choice since it automatically scales based on traffic, but I'm not entirely sure if it can handle those sudden spikes effectively.

I'm a little confused by the differences between the instance group options. I'll need to research those more to understand how they handle autoscaling and resource provisioning.

Okay, I think I've got a strategy for this. I'll focus on the key requirements of cost optimization and handling traffic spikes, and then evaluate how each platform addresses those needs.

Why not just use a hamster on a wheel to power the backend? Probably cheaper than all these cloud options.

I agree with Basilia. With cluster autoscaling, we can efficiently handle traffic spikes without over-provisioning.

Kubernetes Engine with autoscaling is the way to go. It's like having your own personal cloud army to handle all the traffic.

I'd go with Compute Engine with managed instance groups. That way you have more control over the instances and can optimize them for your specific needs.
