This book takes a hands-on, practical approach, blending theory with actionable examples to help you design, build, and maintain robust, scalable, and high-performance backend applications. Whether you are working with monolithic applications or microservices, this guide equips you with the tools and knowledge to implement modern server-side architectures, optimize performance, and ensure reliability under heavy load.

Inside, you’ll learn how to:

• Harness Kotlin’s language features and JVM internals for backend performance and scalability.

• Build APIs and microservices using Ktor and Spring Boot, following best practices for routing, serialization, error handling, and security.

• Implement coroutines and asynchronous programming patterns to maximize throughput and responsiveness.

• Design resilient database interactions, manage transactions, handle migrations, and optimize queries for production workloads.

• Write comprehensive unit, integration, and API tests, and integrate them into CI/CD pipelines for automated deployments.

• Apply advanced observability techniques, including logging, metrics, monitoring, and distributed tracing, to detect and debug production issues safely.

• Manage configuration, secrets, and environments across development, staging, and production.

• Deploy Kotlin services in the cloud, containerize applications with Docker, and implement scaling strategies for high-load environments.

• Maintain backward compatibility, handle API versioning, and gradually refactor legacy systems to reduce technical debt and improve long-term maintainability.

With clear explanations, practical code examples, and real-world insights, this book is designed for intermediate to advanced developers who want to take their Kotlin backend skills to the next level. It bridges the gap between learning Kotlin and applying it effectively in production, helping you build systems that are not only functional but resilient, scalable, and maintainable over time.

Whether you are developing APIs, microservices, or full-scale backend systems, Production Kotlin for Backend Systems provides the comprehensive roadmap for designing, testing, deploying, and maintaining high-quality Kotlin applications in real-world production environments.
