[All Google Cloud Architect Professional Questions]

You company has a Kubernetes application that pulls messages from Pub/Sub and stores them in Firestore. Because the application is simple, it was deployed as a single pod. The infrastructure team has analyzed Pub/Sub metrics and discovered that the application cannot process the messages in real time. Most of them wait for minutes before being processed. You need to scale the elaboration process that is I/O-intensive. What should you do?

AConfigure a Kubernetes autoscaling based on the subscription/push_request metric.

BUse the --enable- autoscaling flag when you create the Kubernetes cluster

CConfigure a Kubernetes autoscaling based on the subscription/num_undelivered message metric.

DUse kubectl autoscale deployment APP_NAME --max 6 --min 2 --cpu- percent 50 to configure Kubernetes autoscaling deployment

That's a good point, but I still think configuring based on the num_undelivered message metric would be more effective.

I disagree, I believe we should use kubectl autoscale deployment APP_NAME --max 6 --min 2 --cpu-percent 50 to configure autoscaling.

Haha, I bet the infrastructure team is pulling their hair out trying to keep up with all those messages! Option D looks good, but I'd probably go with C to be safe.

I think Option D could also work well, but I see your point about going with Option C for safety.

I agree, the infrastructure team must be stressed out. Option C does seem like a safer choice.

Option C seems like the way to go. Scaling based on the num_undelivered message metric makes sense for an I/O-intensive application.
