Building IoT projects with AWS Greengrass

In this section, we will build a simple scenario to access AWS Greengrass. We will build an AWS Lambda application into AWS Greengrass. Then, we will access it from the client application. Our scenario is illustrated in the following figure:

To implement this demo, we will perform the following tasks:

1. Prepare libraries on AWS Greengrass Core
2. Create AWS Lambda
3. Deploy AWS Lambda to AWS Greengrass
4. Test

Each task will be explained in the following sections.

Preparing runtime libraries on AWS Greengrass Core

The first task to ensure our AWS Lambda runs well on AWS Greengrass Core is to prepare all requirement modules/libraries. In general, we can define three modules/libraries that should...
