About this book:

This book provides a comprehensive guide to modern backend architectures, focusing on the transition from centralized servers to a distributed continuum of serverless functions, edge compute, and programmable CDNs. It details how moving code and data closer to the user minimizes latency while leveraging the elastic, pay-per-use economics of serverless models to handle fluctuating demand. The text emphasizes that while these technologies offer unprecedented speed and scalability, architects must carefully manage trade-offs between global data consistency, performance engineering, and operational complexity.

The core of the book explores the technical building blocks required for resilient, event-driven systems. It covers a wide array of topics, including compute models like WebAssembly and micro-containers, sophisticated networking and caching strategies at the edge, and the orchestration of complex business workflows using Sagas and state machines. Significant attention is given to data management, comparing serverless SQL and NoSQL databases and outlining patterns for geo-sharding and replication to maintain availability across global regions.

Security and observability are treated as first-class concerns, with the author advocating for Zero Trust principles, mutual TLS, and WAF mitigation enforced at the network perimeter. The book also addresses the operational lifecycle of modern apps, detailing structured logging, distributed tracing, and the necessity of Infrastructure as Code and Policy as Code for maintaining compliance and governance. It stresses that a "shift-left" approach to security and performance is essential for managing the high volume of ephemeral components inherent in these architectures.

The final chapters provide practical deployment recipes and case studies—ranging from IoT ingestion pipelines to e-commerce personalization—to ground these theories in real-world scenarios. The book concludes with a "Decision Framework Playbook" and a look toward the future, highlighting the emerging roles of AI-powered observability and autonomous operations. Ultimately, it serves as a pragmatic manual for architects to build cost-aware, resilient, and ultra-responsive applications that meet the demands of a globally distributed user base.

What You'll Find Inside:

• Understand the trade-offs of edge and serverless architectures for latency, scalability, and cost, and when to apply them.
• Master event-driven design principles to build loosely coupled, resilient systems using queues, streams, and pub/sub.
• Learn to choose and optimize the right compute model (functions, edge workers, micro-containers) for different workloads.
• Implement effective data strategies at the edge, including caching, KV stores, and global data consistency patterns.
• Apply operational best practices for observability, reliability, security, and cost management in distributed edge and serverless systems.

Who's It For:

This book is intended for software architects, backend engineers, and platform teams seeking to design and implement scalable, low-latency backend systems using serverless functions, edge compute, and CDN-driven logic. Readers will gain practical knowledge on event-driven architecture, data management at the edge, and operational best practices for building resilient and cost-effective applications. It is especially valuable for those working on globally distributed applications or modernizing legacy systems with cloud-native patterns.
