Price per hour or per month

Hello,

I am looking for a host for my Node.js applications. They are low-traffic applications - I expect an average of 1 hour of use per day, so I am looking for a package where I can pay per use only. I noticed that your cloud VPS packages are priced per hour of use, but, I am not sure how is “use” defined.

DigitalOcean FAQ says that: “If you use your server for less than 672 hours during the month, you will be billed for each hour that you used it. If you use your server for more than 672 hours that month, you will be billed at the monthly cost”. But on the other hand, in the next question they say: “Am I charged while my Droplet is in a powered-off state? - Yes. Your diskspace, CPU, RAM, and IP address are all reserved while your Droplet is powered off”. If I understand this correctly, this means that, even when no one enters my website, they charge me as if I do use the site.

So, my question is, what package should I choose, in order to be charged 1 hour per day?
