tl;dr Rewrote an #AWS APIGateway & #lambda service that was costing us about $16000 / month in #elixir. Its running in 3 nodes that cost us about $150 / month. 12 million requests / hour with sub-second latency, ~300GB of throughput / day. If they continued to stay serverless, it would've cost 30K USD per month for API gateway alone. $3.50/ 1 million requests @ 12 million / hour $3.5x12x24x30 = $30k https://twitter.com/coryodaniel/status/1029414668681469952 https://twitter.com/coryodaniel/status/1029414668681469952
