Overview of this book

The Internet of Things market increased a lot in the past few years and IoT development and its adoption have showed an upward trend. Analysis and predictions say that Enterprise IoT platforms are the future of IoT. AWS IoT is currently leading the market with its wide range of device support SDKs and versatile management console. This book initially introduces you to the IoT platforms, and how it makes our IoT development easy. It then covers the complete AWS IoT Suite and how it can be used to develop secure communication between internet-connected things such as sensors, actuators, embedded devices, smart applications, and so on. The book also covers the various modules of AWS: AWS Greengrass, AWS device SDKs, AWS IoT Platform, AWS Button, AWS Management consoles, AWS-related CLI, and API references, all with practical use cases. Near the end, the book supplies security-related best practices to make bi-directional communication more secure. When you've finished this book, you'll be up-and-running with the AWS IoT Suite, and building IoT projects.

Introducing AWS Greengrass

AWS Greengrass is one of the AWS services that enables you to build the AWS IoT server locally. This solution has an advantage, because our IoT devices should not connect to AWS IoT directly.

AWS Greengrass acts as a bridge or gateway for connected IoT devices. It offers AWS computation, such as AWS Lambda. We can deploy our own service over AWS Lambda on AWS Greengrass. AWS Greengrass can be implemented on a computer or device-based ARM CPU. All devices that are used for AWS Greengrass should be registered to AWS IoT. IoT devices have access to AWS Greengrass and AWS Greengrass needs to be configured in one group so that both the IoT devices and AWS Greengrass can communicate with each other.

A general overview of AWS Greengrass is depicted in the following figure. Each IoT device can connect to AWS Greengrass to perform computation without connecting to the AWS server. IoT devices and AWS Greengrass can only communicate within the Greengrass Group:
