I’m a bit confused about the differences between the options. I thought using App Engine's Cron service was more straightforward, but now I'm wondering if GKE is actually more reliable.

Kristofer 4 months ago

I feel like we practiced a question similar to this, and I think the key was to ensure messages are published to a topic. So, maybe D is the way to go?
