Which leads to a potential constructive suggestion. Maybe Goog can post a troubleshooting guide that lists different line-items in the new-style billing, and potential gotchas? An example in your blog is that sudden parallelism is costly and that making things serial is a good optimization. (Ironically, the opposite of what was being promoted earlier - mapreduce). Another factoid is that offset queries are costly. Using queries as a generator is costly, and you should fetch items at once.
So it can look like this: Excessive instances cost? Look at these items: - sudden parallelism - idle instance setting - decrease response time - other? Excessive writes: - decrease unneeded indexes - Excessive Reads: - make sure your fetch() rather than looping through results - check offset queries - etc...
