Jumpstart Your Micronaut Applications with AWS Lambda
In this 9-hour workshop, JVM developers learn how to develop and deploy Micronaut® applications to AWS Lambda.
Overview
Through a combination of lectures, live coding demonstrations, and AWS interaction, participants learn:
- How AWS Lambda functions written with the Micronaut framework can be triggered with AWS Events (such as an S3 or DynamoDB event)
- How integrating Amazon API Gateway and AWS Lambda enables you to write your applications as you would with a Netty runtime (i.e., write your applications as you usually do; run them in AWS Lambda)
- How to deploy a Micronaut application as a GraalVM native image to AWS Lambda Java runtime or to a custom runtime
- How leveraging certain characteristics of Micronaut applications, including fast startup, low memory consumption, and GraalVM integration, can help you work around cold startups in AWS Lambda
INTENDED AUDIENCE
This workshop is a great learning opportunity for JVM developers interested in learning how to integrate Micronaut applications with AWS services.
PREREQUISITES
Although everyone is welcome, we recommend attendees have at least a working familiarity with web development, HTTP, Java, and JVM development frameworks.
Experience using the Micronaut framework and AWS is a plus, but not required.

Technical Requirements
- IntelliJ IDEA. The instructor uses IntelIiJ IDEA Ultimate during the course. Attendees should come with JDK 8 or JDK 11 and either IntelliJ IDEA Community (free, open source) or IntelliJ IDEA Ultimate (free trial available) installed on their computers. Both versions can be downloaded at https://www.jetbrains.com/idea/download.
- SDKMAN! We recommend installation of the Software Development Kit Manager (SDKMAN!) to ease changing the Java version. Download SDKMAN! at https://sdkman.io.
- AWS. We recommend that every attendee create a personal AWS account prior to the workshop for use during the course. You can create a free account at https://aws.amazon.com/free/.
- AWS Command Line Interface. https://aws.amazon.com/cli/
- AWS CDK CLI. https://docs.aws.amazon.com/cdk/v2/guide/cli.html
- GitHub. Attendees will require a GitHub account, so that code samples and documentation can be shared. If you don't already have one, create your free GitHub account at https://github.com/.
