I got an answer from support that workflows payment based on Toogle = enable state.
"So that price is per configured workflow meaning it would calculate with "enable" if I understand this correctly.
Basically you pay for the existence of the workflow"
Regardless of real execution time. So every workflow will cost annually based on MSRP: more than 1138.8 USD
Is it correct?
Based on well known https://blog.rowanudell.com/the-serverless-compute-manifesto/
Fair principle to this type of function: Never pay for idle
These docs give a good example of the cost for both time existing and usage. Automation workflows (DPS) | Dynatrace Docs. From the description in the docs and the pricing, yes it would be roughly 1138.8 USD per year at the time of writing.
Hope that helps.
