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.

Developing a Deployment policy

As mentioned previously, to deploy a service on an Edge node, in addition to a Service policy, we also need a Deployment policy.

The Deployment policy works very similarly to a Service policy and has a similar concept of Properties and Constraints. Once again, we’ll create a deploy policy file in JSON format to specify name-value pairs with logical expressions. Here, the goal is to use name-value pairs with target deployment scenarios in perspective. Note that the deployment policy has more details in addition to Properties and Constraints.

Note

In practice, the Service policy and Deployment policy are combined internally by the Open Horizon Management Hub while evaluating the Agreement that results in the actual deployment of services on the qualifying nodes. Some software developers just use the Deployment policy and combine Service policy constraints in the Deployment policy itself. Understanding the semantics of a Service policy versus...
