Hands-On Serverless Applications with Kotlin

By: Hardik Trivedi, Ameya 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.

Monitoring crashes

When you create your application with your dedicated time and effort, you will obviously make sure that it's treated with love when it reaches the end user. Your user hates crashes. How do you gracefully handle them and fix them? Firebase's crashlytics is the answer.

Firebase Crashlytics (initially owned and known as Fabric) is a lightweight, real-time crash-reporter tool. This helps us to catch all the incorrect behavior in the app. We can track the issues and later prioritize and fix them. Track | Prioritise | Fix this cycle will help your app gain stability. With the facility to track the events and behavior with custom keys, it saves time in troubleshooting the crash. You don't need to debug the app to find the crash. The unique key in the code will tell you where it's coming from.

Its key capabilities are as follows:

  • Well-designed crash...
