In an era where scalability, resilience, and agility define successful software systems, this book offers a hands-on roadmap to mastering event-driven, serverless architectures.

The book guides you, step by step, through building a real-world distributed order-processing system—starting from a single Azure Function and expanding into a robust, fully integrated, and production-ready cloud solution. You will learn how to design ingestion pipelines with HTTP triggers and queues, orchestrate workflows with Durable Functions, manage data in Cosmos DB, implement event-driven flows using Event Grid, and monitor system health with Application Insights. 

Through its structured approach, this book bridges foundational concepts with practical engineering patterns. The first section establishes the core principles of distributed systems, event-driven design, and serverless computing using Azure Functions. The next section explores orchestration, workflow automation, security, and observability—equipping you with integration techniques for real-world enterprise systems. And the operations and advanced section delves into CI/CD pipelines, Infrastructure as Code (IaC), and modern deployment strategies.

By the end of the book, you will have a complete reference architecture that mirrors real-world systems such as ecommerce checkouts, financial workflows, or insurance claims processing—preparing them to confidently design, deploy, and scale resilient serverless systems in .NET and Azure.

What You Will Learn

• Design real production-grade serverless architectures on Azure
• Use Azure Functions, Durable Functions, Event Grid, Service Bus, Cosmos DB, Azure Storage, and API Management together
• Handle the hard concerns, including idempotency, orchestration vs. choreography, failure compensation instead of try/catch, event contracts and versioning, observability and tracing, secure B2B/API-to-API flows, zero downtime deployments, and cost-control under scale
• Evolve an initially simple Azure Function into a mature, modular, multi-service, maintainable serverless system using domain-driven thinking, event modelling, and clean architectural boundaries
• Take a full system from development to production, including CI/CD pipelines, environment isolation, secret management, networking, and much more

Über Autor(innen)

Patrick Kearns is a senior software engineer, architect, and DevOps practitioner with more than three decades of professional experience, including more than 20 years working with .NET. He has worked across ecommerce, finance, insurance, and enterprise SaaS, helping teams design, build, and?operate?distributed systems where reliability and scalability are critical.
Patrick began his career building monolithic systems using early versions of ASP.NET and WCF. As the industry shifted toward microservices and event-driven architectures, he gained hands-on experience with the practical challenges of distributed systems, including latency, partial failure, and operational complexity. His work spans high-throughput ecommerce platforms and compliance-driven insurance systems, where architectural decisions had direct business impact
Patrick lives in Ireland, where he balances his work in technology with family life, writing, and creative projects. He continues to experiment, learn, and share knowledge, believing that the best way to master complex systems is to explain them clearly to others. His hope is that this book will help .NET developers feel confident tackling distributed, event-driven systems, and that it will provide both the technical guards and the mental models needed to succeed.
