Project mention: Serverless applications on AWS using Lambda with Java 25, API Gateway and DynamoDB - Part 1 Sample application | dev.to | 2026-03-16
In this application, we will create products and retrieve them by their ID and use Amazon DynamoDB as a NoSQL database for the persistence layer. We use Amazon API Gateway, which makes it easy for developers to create, publish, maintain, monitor, and secure APIs. Of course, we rely on AWS Lambda to execute code without the need to provision or manage servers. We also use AWS SAM, which provides a short syntax optimised for defining infrastructure as code (hereafter IaC) for serverless applications. For this article, I assume a basic understanding of the mentioned AWS services, serverless architectures on AWS, and AWS SAM. The application is intentionally fairly simple. The goal is to demonstrate the general development concepts and cover approaches to reduce the cold start time of the Lambda. Please also watch out for another series where I use relational serverless Amazon Aurora DSQL database and additionally Hibernate ORM framework instead of DynamoDB to do the same Lambda performance measurements.
