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.

Implementing other lambda functions in Kotlin

I am sure testing the sample lambda function works for you. Once this is done, we can move ahead and complete other lambda functions one by one. Since the preceding one was the dummy one, in this section we will modify it and add other functions. We will cover the following functions in this section:

  • Registering respondent
  • PollsCreator
  • PollGetter

Preparing the data classes

We already discussed the importance of data classes and how they work. Since now we are doing the actual implementation, it's time to restructure it and modify some of them.

In the source code, you will see mainly three files: requests/RequestModels.kt, responses/ResponseModel.kt, and Models.kt:
