Overview of this book

Software Architecture with Kotlin explores the various styles of software architecture with a focus on using the Kotlin programming language. The author draws on their 20+ years of industry experience in developing large-scale enterprise distributed systems to help you grasp the principles, practices, and patterns that shape the architectural landscape of modern software systems. The book establishes a strong foundation in software architecture, explaining key concepts such as architectural qualities and principles, before teaching you how architectural decisions impact the quality of a system, such as scalability, reliability, and extendability. The chapters address modern architecture topics such as microservices, serverless, and event-driven architectures, providing insights into the challenges and trade-offs involved in adopting these architectural styles. You’ll also discover practical tools that’ll help you make informed decisions and mitigate risks. All architectural patterns in this book are demonstrated using Kotlin. By the end of this book, you’ll have gained practical expertise by using real-world examples, along with a solid understanding of Kotlin, to become a more proficient and impactful software architect.

Idempotency

Idempotency is a concept in software engineering that refers to the non-functional property of operations that can be performed multiple times while still having the same effect as performing it only once. In other words, an idempotent operation can be safely repeated without side effects. Let’s cover a short scenario where idempotency is required.

A use case where idempotency is required

Imagine that we’re building an online banking application. A key capability is Transfer Funds, in which a user transfers money from one account to another. This capability is a fundamental yet critical part of the system, and it needs to be implemented in a way that ensures the integrity and reliability of the user’s financial transactions.

If the Transfer Funds operation isn’t idempotent, then the user could accidentally click the Transfer button multiple times, and the system would execute the transfer operation multiple times, resulting in an unintended...
