Module 3 (Part 1): Lambda Functions on AWS Greengrass

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 shows you how to deploy a Lambda function on the AWS Greengrass core that sends "Hello World" messages to the AWS Greengrass cloud. Part 2 covers the differences between on-demand and long-lived Lambda functions running on the AWS Greengrass core. Before you begin, make sure that you have completed Module 1 and Module 2 and have a running AWS Greengrass core device. Note that Module 3 (Part 1) and Module 3 (Part 2) should take approximately 30 minutes each.
