Summary

We packed a ton into this chapter, providing an introduction and overview of edge computing and building an example to learn firsthand how everything works. More than likely, you are already thinking about your specific scenarios and itching to get started. Let’s take a moment to consider what we have accomplished.

First, we deployed AWS Greengrass to an edge computer or device and then connected it to the AWS cloud to help manage the device. Then, we developed and deployed several components – one of each type of component: a custom-developed component, a public component, and an out-of-the-box Greengrass community component. The way each of those works is slightly different, but they work well together to accomplish our goals. Finally, we tied everything together to request some Modbus data. We queried a remote Modbus slave for the data, and then returned this data and forwarded it to the cloud.

We went beyond the basic HelloWorld example in this chapter...
