Modern Cloud-Native Microservices

Build real-world, production-grade cloud-native systems with Kubernetes, GitOps, and a polyglot stack - from microservices to serverless and beyond.

The cloud-native world is evolving faster than ever. Kubernetes, GitOps, observability, and secure supply chains are no longer optional - they are the foundation of reliable, scalable software delivery in 2025 and beyond. This book gives you the complete, hands-on blueprint to design, implement, and operate polyglot microservices with Rust, Go, Python, Node.js, and React/Next.js - all integrated into one end-to-end e-commerce platform.

Inside, you'll learn how to:

• Design domain-driven microservices with database-per-service, gRPC, and event-driven workflows.
• Containerize and secure builds with Docker, BuildKit, Trivy, and Cosign.
• Deploy and scale with Kubernetes, Helm, Kustomize, and GitOps pipelines powered by Argo CD and Flux.
• Add resilience and zero trust using Istio, Linkerd, and OPA/Gatekeeper.
• Instrument observability with Prometheus, Grafana, OpenTelemetry, and Jaeger.
• Harness autoscaling with HPA, KEDA, and Knative to balance performance and cost.
• Ship features safely with canary and blue-green deployments using Argo Rollouts.
• Build a full-stack project - a production-ready polyglot e-commerce system with secure payments, inventory management, recommendations, and a Next.js frontend.

Every chapter is hands-on with practice labs, workflow diagrams, and ready-to-use configuration templates. You won't just read theory - you'll deploy real services, wire up observability, enforce security, and run chaos tests to prove resilience.

Whether you're a Kubernetes engineer, DevOps practitioner, cloud architect, or backend/frontend developer, this book equips you with the patterns, tools, and discipline to build systems that scale, recover, and thrive under real-world pressure.

If you're ready to go beyond tutorials and assemble the full picture of cloud-native delivery, this is your playbook for 2025 and beyond.
