I am developing a a small dictionary app (in Go) that is not likely to get much traffic. Maybe 100 unique visitors per day and each visitor makes 10 queries. Also the app files are very slim. Not more than 100MB altogether. I've looked at the pricing but it is really confusing. For example I don't know what to put at CPU and Memories per hour. On their 'flexible scheme' I tried what seemed to be very low specs: 1 CPU, 128MB memory and 100MB disk space and it turned out to be $39.05 per month! Also on 'Standard scheme' the  most basic instance is B1 which costs $0.05 per hour, amonts to $36 per month!It is ridiculously expensive for lean VPS. So where is the GAE free tire? Am I missing something here? How do you estimate the price that I should expect?
