Learn how to build Kubernetes Operators from scratch using Kubebuilder, step by step. You will create real controllers, work with CRDs, and understand how reconciliation works in practice. By the end, you’ll know how to design, test, and run your custom operator.

Production is down. Dashboards look “green.” Users are still complaining. What went wrong?Traditional monitoring often shows what the system is doing, but not what users are experiencing.This guide introduces you to two powerful mental models:RED Metrics → What your users feelUSE Metrics → What your system is doingTogether, they give you a complete picture—because symptoms and root causes are not the same .Inside this book, you’ll learn how to:Detect issues before users report themCorrelate latency spikes with infrastructure saturationMove from metrics chaos to meaningful observabilityDesign monitoring for modern distributed systemsIf you’ve ever:Struggled to debug production issuesFelt overwhelmed by too many metricsWanted a structured monitoring approachThis book is your shortcut to thinking like an SRE and system architect.

Set up a secure Elasticsearch and Prometheus setup in Kubernetes that can be used in any production environment!

Master AWS IoT Core with this hands-on, comprehensive guide. Learn how to securely connect, manage, and scale your IoT device fleets using MQTT, AWS IoT Greengrass, bulk enrollments, and OTA updates. From edge hardware setups to cloud analytics and Zero Trust security, build enterprise-grade architectures today.

Every post-mortem starts the same way: "We didn't see it coming." This book argues that's no longer acceptable — and shows you the science behind predicting deployment risk before it becomes an incident.

The draft ones were never sent. The post-mortems never said what really happened. The meetings never heard what you actually thought. This is the book that does.

Troubleshooting Linux systems can feel like solving a mystery—but the right strategies make all the difference. This ebook teaches practical techniques, tools, and real-world approaches that help you diagnose problems faster and fix them with confidence.

Stop being the on-call engineer for your own house. Build a homelab that monitors, alerts, and fixes itself — entirely managed as code.

Your developers are not slow. Your system is full of friction.What if:A new engineer could ship to production on day one?Every service was secure, observable, and compliant by default?Deployments rolled back automatically before customers noticed?Cloud costs were visible at the moment code was written?This is not a tooling problem. It is a platform design problem.The Paved Road shows you how to move from DevOps culture to Platform execution — from heroics to systems, from tickets to self-service, from firefighting to flow.Build the road once. Let everyone move faster forever.

The “perfect architecture” is a myth. The adaptable enterprise wins. Learn how to design evolutionary systems, quantify technical debt, and align engineering with business ROI.

Enterprise DevOps transformation without the risk of culture change. A complete field guide for practitioners of the Scaled Agile DevOps Maturity Framework, the first enterprise framework to build comprehensive, enterprise-grade governance infrastructure around the organization as it actually operates.

Imagine writing production-grade code with fewer errors, sprint reviews that highlight real insights instead of guesses, and teams that spend less time debugging and more time innovating. This isn’t science fiction, it’s the future of software engineering. AI-Augmented Software Engineering unlocks the practical power of AI tools while grounding you in ethical best practices. Discover how to automate the mundane, amplify your creativity, and shape intelligent systems that serve users all without sacrificing trust, quality, or integrity.Welcome to the next wave of engineering designed with intelligence, driven by values.

Value Stream Mapping for modern software teams. Learn how to measure lead time, expose bottlenecks, eliminate waste, and build a delivery system where value moves efficiently from idea to production.

Growth exposes fragility.The system that works at 10,000 users collapses at 1 million. The deployment process that feels “fine” becomes a liability at scale. The architecture that shipped your MVP becomes the bottleneck for your next market.The question facing modern technical leaders is no longer:“Can we build it?”It is:“Can we scale it, operate it, govern it, and evolve it — without breaking trust, burning out teams, or destroying margins?”This book provides a blueprint for building resilient architectures, high-velocity engineering organizations, and systems designed to survive real-world uncertainty.

Digitale Transformation war das Hype-Thema vor KI. Es gibt allerdings einen nicht geringen Anteil an Fach- und Führungskräften, deren Wissen darüber weiter ausbaufähig ist. Dieses Buch ist eine Einführung für alle diejenigen, die keine "digitalen Pioniere" sind, sondern wissen wollen, was aus dem Thema Digitalisierung auf sie zukommen kann und aus dem Thema KI zusätzlich auf sie zukommen wird.
