Real-World Edge Computing

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.

What is a Management Hub?

As described in earlier chapters, though each Edge node functions autonomously, managing the Edge nodes requires a Management Hub. The Management Hub is where deployable services with access to underlying container images for the application workload and deployment policies are published. Once a node registers with its own set of properties, known as a node policy, the Management Hub determines what services need to go to which nodes as per the constraint of the service, as published in the deployment policy earlier. So, the Management Hub only participates in the control plane and is not involved in the data plane, which is the sole responsibility of the application code and developers.

As mentioned earlier, the Management Hub has several components, such as the exchange, agbot, secrets manager, Fido Device Onboard (FDO) system, model management system (MMS), and others, backed by several databases. All components are deployed as containers. In commercial...
