IoT Edge Computing with MicroK8s

By: Karthikeyan Shanmugam

Overview of this book

Are you facing challenges with developing, deploying, monitoring, clustering, storing, securing, and managing Kubernetes in production environments as you're not familiar with infrastructure technologies? MicroK8s - a zero-ops, lightweight, and CNCF-compliant Kubernetes with a small footprint is the apt solution for you. This book gets you up and running with production-grade, highly available (HA) Kubernetes clusters on MicroK8s using best practices and examples based on IoT and edge computing. Beginning with an introduction to Kubernetes, MicroK8s, and IoT and edge computing architectures, this book shows you how to install, deploy sample apps, and enable add-ons (like DNS and dashboard) on the MicroK8s platform. You’ll work with multi-node Kubernetes clusters on Raspberry Pi and networking plugins (such as Calico and Cilium) and implement service mesh, load balancing with MetalLB and Ingress, and AI/ML workloads on MicroK8s. You’ll also understand how to secure containers, monitor infrastructure and apps with Prometheus, Grafana, and the ELK stack, manage storage replication with OpenEBS, resist component failure using a HA cluster, and more, as well as take a sneak peek into future trends. By the end of this book, you’ll be able to use MicroK8 to build and implement scenarios for IoT and edge computing workloads in a production environment.

What is IoT?

According to Gartner (https://www.gartner.com/en/information-technology/glossary/internet-of-things), IoT is a network of physical objects that contain embedded technology to communicate and sense or interact with their internal states or the external environment. In simple terms, IoT refers to the process of connecting all the world's devices to the internet.

IoT devices can range from everyday objects such as lightbulbs to healthcare assets such as medical gadgets, wearables, smart devices, and even traffic lights in smart cities.

Here are a few examples of IoT use cases:

  • Virtual reality (VR) and augmented reality (AR)
  • Smart cities
  • Industrial IoT
  • Self-driving cars
  • Smart thermostats
  • Smart homes
  • Smartwatches

A typical IoT system sends, receives, and analyzes data continuously in a feedback loop. Humans or AI and ML can do analysis in near real time or over a longer period of time. Gartner estimated that there would be 20...
