"My company moved the work of 40 dedicated servers onto Lambda and in doing so decimated our costs. Paying for 1500 cores (our current AWS limit) in 100ms increments has been a game changer" - http://bit.ly/2mcI4C0 "AWS Lambda: 9 million API calls for < $1" - http://bit.ly/2nfCsYR "Oh, and if you are curious about how much this set-up costs per month? It is such an embarrassingly low number, that we hesitate to share it. Let’s just disclose that it is not enough to buy the two of us lunch. Really." - http://bit.ly/2nfAhEM instant.cm
