Edge Computing Systems with Kubernetes: A use case guide for building edge systems using K3s, k3OS, and open source cloud native technologies

Understand how to use K3s and k3OS for different use cases and discover best practices for building an edge computing systemKey FeaturesA guide to implementing an edge computing environmentReduce latency and costs for real-time applications running at the edgeFind stable and relevant cloud native open source software to complement your edge environmentsBook DescriptionEdge computing is a way of processing information near the source of data instead of processing it on data centers in the cloud. In this way, edge computing can reduce latency when data is processed, improving the user experience on real-time data visualization for your applications. Using K3s, a light-weight Kubernetes and k3OS, a K3s-based Linux distribution along with other open source cloud native technologies, you can build reliable edge computing systems without spending a lot of money.In this book, you will learn how to design edge computing systems with containers and edge devices using sensors, GPS modules, WiFi, LoRa communication and so on. You will also get to grips with different use cases and examples covered in this book, how to solve common use cases for edge computing such as updating your applications using GitOps, reading data from sensors and storing it on SQL and NoSQL databases. Later chapters will show you how to connect hardware to your edge clusters, predict using machine learning, and analyze images with computer vision. All the examples and use cases in this book are designed to run on devices using 64-bit ARM processors, using Raspberry Pi devices as an example.By the end of this book, you will be able to use the content of these chapters as small pieces to create your own edge computing system.What you will learnConfigure k3OS and K3s for development and production scenariosPackage applications into K3s for shipped-node scenariosDeploy in occasionally connected scenarios, from one node to one million nodesManage GitOps for applications across different locationsUse open source cloud native software to complement your edge computing systemsImplement observability event-driven and serverless edge applicationsCollect and process data from sensors at the edge and visualize it into the cloudWho this book is forThis book is for engineers (developers and/or operators) seeking to bring the cloud native benefits of GitOps and Kubernetes to the edge. Anyone with basic knowledge of Linux and containers looking to learn Kubernetes using examples applied to edge computing and hardware systems will benefit from this book.Table of ContentsEdge Computing with KubernetesK3s Installation and ConfigurationK3s Advanced Configurations and Managementk3OS Installation and ConfigurationsK3s Homelab for Edge Computing ExperimentsExposing Your Applications Using Ingress Controllers and CertificatesGitOps with Flux for Edge ApplicationsObservability and Traffic Splitting Using LinkerdEdge Serverless and Event-Driven Architectures with Knative and Cloud EventsSQL and NoSQL Databases at the EdgeMonitoring the Edge with Prometheus and GrafanaCommunicating with Edge Devices across Long Distances Using LoRaGeolocalization Applications Using GPS, NoSQL, and K3s ClustersComputer Vision with Python and K3s ClustersDesigning Your Own Edge Computing System Read more
