I wish these cloud providers would "open source" their pricing models. I know some people were probably abusing the hell out of the matrix api but the price hike is quite insane tbh. Maybe this sounds dumb but it's for this reason that I go with Digital Ocean for my personal stuff.

For example, something like: compute time + availability + hardware + ?

At least with lambdas you can average out time through individual function blocks and scope it to hopefully know what pieces of the users code are the most intensive. Maybe lambda get us closer to this transparency model by showing us down to the functional block what is costing what.
