If you are running on Heroku or Google App Engine, you don&#x27;t have a server as well. AWS Lambda abstracts the concept of a server even more, but yeah...<p>I also think the costs are pretty high. Of course I have no idea how much traffic and requests where calculated, so I am just guessing. As cloudfront and S3 do the heavy lifting, a cheap server or two for actual editing of the content should be enough. And they don&#x27;t need to scale on the same level as there won&#x27;t be that much changing for customers, so paying more than 10,000$ for that with 100.000 customers seems pretty high.<p>But I get what the idea behind it was, and it seems to work pretty good. Also nice to have really low costs in the beginning :)
