Chapter 3: Building the Edge

In this chapter, you will learn about edge solution concepts such as gateways and how AWS IoT Greengrass is used as a powerful edge appliance to interact with physical interfaces and leaf devices. The goal of this chapter is to start building proficiency with the use of IoT Greengrass for the writing and deploying of software components. This material is foundational to much of the book's hands-on projects and for understanding how we build solutions for the edge.

We will introduce you to the different protocols that IoT Greengrass can support out of the box and discuss commonly used protocols when building edge solutions. Additionally, we will review several security best practices for you to learn how to keep your edge workloads protected from threats and vulnerabilities. The chapter concludes with a hands-on activity to connect your first two device capabilities as components, whether using actual hardware or a pair of simulators.
