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.

Overview of the Istio service mesh

Istio is an open source platform-independent service mesh that manages traffic, enforces policies, and collects telemetry. It is a platform for managing communication between microservices and applications. It also provides automated baseline traffic resilience, service metrics collection, distributed tracing, traffic encryption, protocol upgrades, and advanced routing functionality for all service-to-service communication without requiring changes to the underlying services.

The following are some of the vital features of Istio:

  • Secure service-to-service communication via TLS encryption, strong identity-based authentication, and authorization
  • Automatic load balancing for HTTP, gRPC, WebSocket, and TCP traffic
  • Fine-grained traffic control via rich routing rules, retries, failovers, and fault injection
  • A pluggable policy layer and configuration API that supports access controls, rate limits, and quotas
  • Automatic metrics...
