graviton2-lambda

A simple Lambda function built with Java (Corretto 11) to be deployed twice: once using AWS's new Graviton CPU architecture and once, without.

Each deployed function is behind a REST API method allowing us to test the performance and cost of each deployment.

The entire stack is deployed using CloudFormation (see template.yml).

Build and Deploy

$  ./gradlew -q clean packageLibs && mv build/distributions/graviton2.zip build/distributions/graviton2-lib.zip && ./gradlew -q build

$  aws cloudformation package --template-file template.yml --s3-bucket graviton2-tester-src  --output-template-file out.yml

$  aws cloudformation deploy --template-file out.yml --stack-name gaviton2 --capabilities CAPABILITY_NAMED_IAM --region us-east-1

These commands respectively:

• Build and package the application: function and its dependency JARs are packaged in 2 separate zip files
• Prepare CloudFormation template: upload zip files to S3 and update the template with S3 URIs
• Deploy the CloudFormation stack.

Notes

• Prior to these steps, you have to create the graviton2-tester-src S3 bucket. DO NOT make the bucket public. Instead, configure your AWS CLI correctly to be able to upload source zip file to S3 (when running aws cloudformation package).
• As it can be seen, gradlew is used for building the app. The wrapper script will automatically pull gradle the first time it runs. thus, one doesn't need to install gradle.
