Serverless Microservices

" summary

Proposes replacing servers with AWS API Gateway + Lambda to run Clojure/ClojureScript service functions, with a single-page Reagent app hosted on S3, Cognito for authentication, and DynamoDB for storage; demonstrates scraping EC2/Lambda pricing via a Lambda proxy and signup/login flows that write to DynamoDB. Notes Lambda is billed by 100ms slices, has a 60s max execution, JVM cold starts push prefer Node/ClojureScript, and deployment uses Swagger import plus clj-s-lambda; it works for low-to-moderate traffic but tooling and docs remain flaky.
