I'm not sure, but I hope the bank's customers don't get so many notifications that they start using their accounts to play the lottery instead.

Option C is an interesting approach, but I'm not sure about the idea of using the average of all account balance predictions to trigger notifications. Shouldn't we focus on individual users' accounts?

Option B looks good, but I'm not sure if the App Engine standard environment is the best choice for a global banking application. It might be overkill for this use case.

I'm leaning towards Option D. Using Firebase Cloud Messaging to send targeted notifications to each user based on their individual account balance predictions seems like a robust solution.

Option A seems like the most straightforward approach. Using a Pub/Sub topic for each user and a Cloud Function to handle the notification logic seems efficient and scalable.

That's a good point, but I still think option A is more efficient for notifying users in real-time.

I disagree, I believe option C is better as it sends a notification based on the average of all account balance predictions, providing a more comprehensive approach.

I think option A is the best choice because it directly sends a notification when the account balance is predicted to drop below $25.
