Load testing results of the book_nanny endpoint, when using step functions versus using lambda. Step functions did the task within half the time it took for lambda to get it done

You can deploy the application on your local machine without needing an AWS account, using LocalStack. LocalStack is a cloud emulator that runs various AWS services on your local machine. It spins up a testing environment on your local machine that provides the same functionality and APIs as the real AWS cloud environment.
To run the application locally, you need to setup the following prerequisites on your machine:
Before you can run the application locally, you need to start LocalStack. You can do this by running the following command:
export LOCALSTACK_AUTH_KEY=<YOUR_AUTH_KEY>
localstack start -dIf you don't have an auth key, you can get one by creating an account on LocalStack Web Application and signing up for a Hobby Plan.
You can build the SAM application by running the following command:
sam build --use-container After successfully building the application, you can deploy it locally by running the following command:
samlocal deploy --resolve-s3The samlocal script is a wrapper around the sam CLI that configures the endpoint URL parameter for each AWS service to point to the LocalStack container.
After a successful deployment, you should see the following output:
