Functional Web Apps - The Revenge of Dynamic Web Apps
summary
Argues that massively available dynamic sites are best built with pure cloud functions that render HTML on demand, use serverless databases (DynamoDB, Fauna, Cosmos) and declarative deployment via Architect/Begin on AWS. Shows a working CRUD to‑do built with four Lambdas, an S3 static bucket and a DynamoDB table, and claims the arc 19‑line config expands to arc 19-line config -> 1,400-line CloudFormation. Recommends small functions to avoid cold starts with a rule of thumb keep payload <5MB for cold-start <1s. Functional Web Apps demonstrates faster deploys and simple rollbacks.
