Greengrass

Greengrass is the new generation of the IoT Edge by AWS. AWS supports an SDK to build the AWS edge and extends cloud capabilities to edge devices with Greengrass. This enables them to carry out actions locally, while still using the cloud for management, analytics, and permanent storage. Greengrass supports OPC UA but not the OPC Classic interface. We will be discussing Greengrass in more detail in Chapter 10, Implementing a Cloud Industrial IoT Solution with AWS.
