Strangeways, Here We Come
summary
A natural language engine gets migrated from on‑prem into AWS as a cluster of Fargate containers behind API Gateway -> VPC Link -> NLB -> Fargate -> RDS, with authentication via Cognito for auth and secrets in Secrets Manager. Deployment uses CloudFormation — roughly about a thousand lines of infrastructure as code — plus CloudWatch alarms and PagerDuty for incident response. Design choices include no public IPs, avoiding NLB health checks, and a five‑VPC‑link account limit; outcome: faster releases and fewer on‑prem change‑window failures.
