As expected, best results are achieved with the Redis cache. Interesting that, for the cold start, using DynamoDB performs worse than without AWS caching.

Drew Eckhardt's answer to Why does Dropbox still use Amazon S3 to store data instead of building its own data center? Is it still cost effective for Dropbox? - Quora
Gross profits at now + time t are current revenue * growth ^ t * gross margin where gross margin is  ((revenue - cost of goods sold) / revenue). Generally it's much better for startups to devote resources to increasing growth as the exponent base than reducing cost of goods sold which merely multiplies the effects of the exponentation with a limit somewhere below a 100% gross margin.

Use of Formal Methods at Amazon Web Services | the morning paper
At AWS, formal methods have been a big success. They have helped us prevent subtle, serious bugs from reaching production, bugs that we would not have found via any other technique. They have helped us to make aggressive optimizations to complex algorithms without sacrificing quality. So far, seven teams have used TLA+, and all have found high value in doing so. At the time of writing, more teams are starting to use TLA+. We believe that use of TLA+ will accelerate both time-to-market and quality of these projects. Executive management is now proactively encouraging teams to write TLA+ specs for new features and other significant design changes. In annual planning, managers are now allocating engineering time to use TLA+.
