Honest question: Can you use Temporal Cloud? Have you evaluated Temporal Cloud pricing?

Ballparking: 200 events/workflow, 200 workflows/per day and assuming 1 event = 1 cloud action[1], that is 1.2M or so actions per month. The $100/month plan includes 1M actions each month, and even the pay-as-you pricing when you exceed that is $50 per 1M actions[2].

Temporal Cloud seems extremely cheap for your use case, even if I'm off by a factor of 10. Is there a catch? You still need infra to run your Temporal workers, and I assume there are storage and other costs, but I assume action usage is the majority of it.

1. Not sure exactly what constitutes an "Action". At a glance, seems like most events have a corresponding action(?) and a subset of those actions are actually billable(?)
