Develop and test your AWS-powered Spring Boot application locally
summary
A Spring Boot backend, React frontend and a Lambda validator are wired to DynamoDB, S3, SNS and SQS via the same terraform IaC; switching endpoints and profiles runs the entire stack in LocalStack Docker with the same Lambda jar and Terraform files. Demo shows full workflow works locally (messages, image watermarking, queue processing); LocalStack claims ~90 services, Lambda fidelity near 100, CI helpers like TF Local and CloudPod, and benchmarks show a 28 minute AWS create vs ~24 second local run.
