Real-World Edge Computing

By: Robert High, Sanjeev Gupta

Overview of this book

Edge computing holds vast potential to revolutionize industries, yet its implementation poses unique challenges. Written by industry veterans Rob High and Sanjeev Gupta, this comprehensive guide bridges the gap between theory and practice. Distilling expertise from their combined decades of experience in edge computing and hybrid cloud mesh solutions, this book equips software developers and DevOps teams with the knowledge and skills needed to deploy edge solutions at scale in production environments. It also explores foundational standards and introduces key factors that may impede the scaling of edge solutions. While edge computing draws from the successes of cloud computing, crucial distinctions separate the two. High and Gupta elucidate these distinctions, helping you grasp the nuanced dynamics of edge-computing ecosystems. With a focus on leveraging Open Horizon to overcome pitfalls and optimize performance, this book will help you confidently navigate the intricacies of constructing and deploying resilient edge solutions in real-world production settings. By the end of this book, you’ll have acquired a deep understanding of essential success factors for building and deploying robust edge solutions in real-world production settings, leveraging Open Horizon for scalable edge deployments.

An overview of patterns

Open Horizon offers two mechanisms for controlling the deployment of services to the Edge. The first of these is referred to as patterns.

Patterns are simple but effective when you’re first kicking the tires with a couple of nodes. A pattern is a JSON file that lists the services you want to deploy with that pattern. Once you’ve written the pattern JSON file, you can publish it with the Management Hub.

After that, you can reference one or more patterns in the Node Policy document associated with the Edge Agent at each of your nodes. We’ll discuss the Node Policy document later in this chapter.

Whenever the Agent on a particular node starts, it will form an agreement with the Agbot to place the services specified in its referenced patterns at that node.

As you can see, this is a quick way of getting a well-known set of services placed on your nodes. However, it is static. The same services will always be placed at that node until...
