Hands-On Serverless Applications with Kotlin

Hands-On Serverless Applications with Kotlin

By: Trivedi, Kulkarni

Overview of this book

Serverless is a cloud computing execution model where the cloud provider dynamically manages the allocation and provisioning of servers. Many companies now use serverless architectures to cut costs and improve scalability. Thanks to its concise and expressive syntax and a smooth learning curve, Kotlin is a great fit for developing serverless applications. With this book, you’ll be able to put your knowledge to work by implementing serverless technology in your applications and become productive in no time. Complete with detailed explanation of essential concepts and examples, this book will help you understand the serverless architecture fundamentals and how to design serverless architectures for your applications. You’ll also explore how AWS Lambda functions work. The book will guide you in designing, building, securing, and deploying your application to production, along with implementing non-functional requirements such as auditing and logging. Furthermore, you’ll discover how to scale up and orchestrate serverless applications using an open source framework and handle distributed serverless systems in production. By the end of the book, you’ll be able to build scalable and cost-efficient Kotlin applications with a serverless framework.
