Scale Your @Controller to Zero with AWS Lambda or Azure Functions

on YouTube ↗42m

" summary

Claims that existing Spring Web @Controller apps run on AWS Lambda or Azure Functions with no code changes, deployed via Spring Cloud Function and Spring Serverless Java Container and packaged with SAM or zip. Demoed an uppercase function and a PetStore controller exposed through API Gateway; both invoke correctly but show cold starts. Mitigation uses AWS Lambda SnapStart (Java 11/17) and immutable versions to restore in milliseconds. Also shows Azure/KEDA options and a Spring Initializr template for AWS Lambda web.
