Course details

Welcome to this hands-on course covering the benefits and limitations of using AWS to create serverless Java applications. In this course, instructor Terezija Semenski shows you how to set up the environment and IntelliJ IDE so that you can develop, deploy, and debug your code on AWS Lambda. Terezija gets you started by writing your first “hello world” serverless application and exposing it via REST API. Plus, she explains how to implement custom inputs and outputs of the Lambda function and best practices around logging, tracing and performance tuning. By the end of this course, you will know how to build efficient serverless Java applications.
