This module shows you how to configure an AWS Lambda function and deploy it to your AWS Greengrass core device. It contains information about MQTT messaging, subscriptions, deployments on AWS Greengrass, and Lambda function configurations.

Part 1 of this module described how to deploy a Lambda function on a AWS Greengrass core that sends "Hello World" messages to the AWS Greengrass cloud. This part explores the differences between on-demand and long-lived Lambda functions running on the AWS Greengrass core. Before you begin, make sure you have completed Module 1, Module 2, and Module 3 (Part 1). This module should take approximately 30 minutes to complete.
