Example, with Upstash redis: i deployed a fly.io connected to upstash. I don't use that service for a month (no query at all), but it still counted in billing.
Wait, is upstash real serverless ? I have to pay for NOT using it ?
This is not what all our customers want, but it is much cheaper to run this way for most fullstack frameworks. It's not ideal for a Redis you don't use at all, though.
We're considering a serverless / metered billing option for this. But what we have is much closer to spinning up a permanent Redis. :)
For now, i had to say goodbye for most of cloud services. Good old VPS for now.
