Intelligent Workloads at the Edge

Overview of this book

The Internet of Things (IoT) has transformed how people think about and interact with the world. The ubiquitous deployment of sensors around us makes it possible to study the world at any level of accuracy and enable data-driven decision-making anywhere. Data analytics and machine learning (ML) powered by elastic cloud computing have accelerated our ability to understand and analyze the huge amount of data generated by IoT. Now, edge computing has brought information technologies closer to the data source to lower latency and reduce costs. This book will teach you how to combine the technologies of edge computing, data analytics, and ML to deliver next-generation cyber-physical outcomes. You’ll begin by discovering how to create software applications that run on edge devices with AWS IoT Greengrass. As you advance, you’ll learn how to process and stream IoT data from the edge to the cloud and use it to train ML models using Amazon SageMaker. The book also shows you how to train these models and run them at the edge for optimized performance, cost savings, and data compliance. By the end of this IoT book, you’ll be able to scope your own IoT workloads, bring the power of ML to the edge, and operate those workloads in a production setting.

Reviewing common standards and protocols

Protocols define the specifications for exchanging messages with an edge solution. This means the format of the message, how it is serialized over the wire, and also the networking protocols for communicating between two actors in the solution. Standards and protocols help us to architect within best practices and enable quick decision-making when selecting implementations. Before diving into the common protocols that are used in edge solutions, first, let's review two architectural standards used in information technology and operations technology to gain an understanding of where IoT Greengrass fits into these standards. Using these as a baseline will help set the context for the protocols used and how messages traverse these models in an edge solution.

IoT Greengrass in the OSI model

The Open Systems Interconnection (OSI) model defines a stack of seven layers of network communications, describing the purpose and media used to...
