About this book:

In "Serverless Backends in Practice," you'll discover a comprehensive guide to designing, deploying, and scaling APIs using serverless platforms. This book demystifies the paradigm shift of serverless computing, moving beyond infrastructure management to empower developers to focus solely on application logic. Covering everything from foundational concepts like Function as a Service (FaaS) and event-driven architecture to practical implementation with API gateways, managed databases, and advanced deployment strategies, it provides a holistic view of building resilient, cost-effective, and highly scalable backends. Whether you're grappling with cold start mitigation, securing distributed systems, or optimizing costs, this guide offers actionable insights and best practices across major cloud providers like AWS, Azure, and Google Cloud.

Dive deep into the intricacies of serverless development, learning how to leverage core concepts and managed services to construct robust CRUD APIs, orchestrate complex workflows, and implement effective caching strategies. The book addresses critical operational concerns, including rigorous testing methodologies (unit, integration, and end-to-end), comprehensive monitoring and distributed tracing for unparalleled visibility, and strategic cost optimization techniques to ensure your serverless solutions remain economically viable. Practical examples and discussions on common pitfalls and anti-patterns help navigate the unique challenges of this evolving landscape, while a forward-looking chapter explores the future of serverless, including its convergence with AI/ML and edge computing.

"Serverless Backends in Practice" is an essential resource for architects, engineers, and DevOps professionals ready to unlock the full potential of serverless technology. It provides not just theoretical knowledge but also pragmatic advice and blueprints for building cloud-native applications that are agile, performant, and ready to meet the demands of any modern application. Master the art of designing, deploying, and scaling serverless APIs, transforming your approach to backend development and embracing a future free from infrastructure constraints.

What You'll Find Inside:

• Master the core tenets of serverless architecture, including Function as a Service (FaaS), event-driven compute, and leveraging managed services for stateless design.
• Implement robust CRUD APIs using serverless functions, API Gateways, and cloud-native databases, learning to handle data persistence and authentication effectively.
• Design and optimize serverless workflows using asynchronous processing with queues and Pub/Sub, as well as orchestration and choreography patterns to build resilient and scalable applications.
• Utilize advanced deployment strategies like Blue/Green, Canary releases, and Feature Flags, coupled with robust CI/CD pipelines, to achieve low-risk, continuous delivery for serverless microservices.
• Gain deep insights into performance, cost, and security for serverless backends through comprehensive monitoring, centralized logging, distributed tracing, and best practices for cold start mitigation and cost optimization.

Who's It For:

This book is essential for architects, engineers, and DevOps professionals eager to build, deploy, and scale APIs on serverless platforms. It's particularly beneficial for those transitioning from traditional architectures, needing practical guidance on event-driven design, and aiming to master cloud-native security, performance, and cost optimization techniques.
