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(?)

I was not clear; I did not mean not 200 a day, it's 10s of thousands of concurrently running workflows, sometimes into the hundreds of thousands, each with 200 events. We run many hundreds of thousands of these a day.

Temporal was a bad fit for us, and we regret it deeply.

Ah. So multiple billion actions per month, and probably multiple million dollars per year on their cloud, if they can even support that load (plus, the vendor lock in and etc). Makes sense.

I'm reasonably sure their cloud product can handle that. you might be in the scale where they want to hold your hand in the transition though.

Given the open source nature of the product, I'm not sure what vendor lock-in you mean. Migrating off cloud to your own infra again is doable. https://daylight.ai/blog/how-we-migrated-off-temporal-cloud-...

Hi, Temporal employee here. Just want to confirm that Temporal Cloud can and does handle this scale, well beyond it, in fact.

As our CEO and co-founder Samar Abbas stated in the keynote at this year's Replay conference (https://youtu.be/BxEB7Y2U9oU?t=532), Temporal Cloud is currently handling 35 billion workflows per day. If you assume that each Workflow averages 10 actions, that translates to more than 10 trillion actions per month.

Later in that keynote, a VP from OpenAI talks about the scale at which they are using Temporal Cloud. That'll give you a sense of the volume for a single customer (obviously a very large one).

what would you use instead?
