This module shows you how to configure a 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.
