Event-driven architecture serves as a foundation for building highly scalable, reliable, and real-time cloud native systems. This book is your guide for designing and operating event-driven systems with AWS serverless services, such as Lambda, EventBridge, Step Functions, SQS, SNS, Kinesis, and DynamoDB.

Readers will understand the foundations of event-driven architecture and AWS serverless basics. The book explores design considerations, best practices, and patterns, with a strong focus on adopting a serverless mindset to accelerate value delivery. The book is structured into five parts: fundamentals, design, building, operating, and advanced concepts. It concludes with an outlook on emerging trends and future directions. It provides practical guidance on applying patterns like CQRS, event sourcing, and orchestration. Furthermore, you will build specialized high-performance systems involving real-time data streaming and persistence patterns like event sourcing, culminating in a complete mastery of operational best practices. Real-world patterns and practices ensure that concepts can be applied directly to production workloads.

By the end of this book, you will be a competent AWS serverless expert, equipped to design, build, and operate mission-critical event-driven systems. You will learn to apply AWS Well-Architected pillars and balance security, observability, cost, and performance while addressing complexities and challenges, such as event ordering, idempotency, testing, and schema evolution.
