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.

Benefits of edge computing

To summarize, data can be analyzed, processed, and transported at the network's edge via edge computing. In other words, the data is analyzed in real time, close to where it is kept, with no latency. Data from IoT devices can be analyzed at the network's edge before being sent to a data center or cloud.

Some of the advantages of edge computing are listed here:

  • High speed, low latency, and great dependability, allowing for faster data processing and content delivery
  • Improved security by dispersing processing, storage, and applications across a diverse set of devices and data centers, making it more difficult for a single outage to bring the network down
  • Provides a much more cost-effective path to scalability and versatility, allowing businesses to enhance their computing capacity by combining IoT devices with edge data centers

While there are many benefits to edge computing, it can also provide operational and architectural...
