IoT Edge Computing with MicroK8s

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.

Frequently Asked Questions About MicroK8s

What does it take to enable edge computing, edge analytics, and edge intelligence?

To meet the needs of modern manufacturing, automotive, or telecommunications industries, it is important to acknowledge that businesses are under tremendous pressure to drive innovation and efficiency on their plant floors. This necessitates a comprehensive methodology that combines new/existing IT products with emerging methodologies, along with the goal of avoiding the time-consuming and error-prone manual configuration of several devices and applications at scale.

The following considerations must be noted while building an edge architecture:

  • Autonomy and resiliency: Because the solution necessitates autonomy, connection interruptions cannot be permitted.
  • Resource constraints: Low compute capability and small footprint of the devices.
  • Security challenges: Data privacy, physical device security, and network security of the connected devices.
  • Manageability: Manage application...
