Learn how to use create faster AWS Lambdas in Java using GraalVM

Building Lambdas in AWS is one of the central aspects for building serverless systems in AWS, but brings potential issues most developers have not had to deal with before, such as cold starts, which is required to start the Java process on first run and can take up to ten seconds. Using GraalVM, a lighter version of Java, can reduce these cold starts to less than a second. This tutorial will set up GraalVM and compare it to Java 11, both using AWS Lambda.
