Hands-On Microservices with Kotlin

By: Juan Antonio Medina Iglesias

Overview of this book

With Google's inclusion of first-class support for Kotlin in their Android ecosystem, Kotlin's future as a mainstream language is assured. Microservices help design scalable, easy-to-maintain web applications; Kotlin allows us to take advantage of modern idioms to simplify our development and create high-quality services. With 100% interoperability with the JVM, Kotlin makes working with existing Java code easier. Well-known Java systems such as Spring, Jackson, and Reactor have included Kotlin modules to exploit its language features. This book guides the reader in designing and implementing services, and producing production-ready, testable, lean code that's shorter and simpler than a traditional Java implementation. Reap the benefits of using the reactive paradigm and take advantage of non-blocking techniques to take your services to the next level in terms of industry standards. You will consume NoSQL databases reactively to allow you to create high-throughput microservices. Create cloud-native microservices that can run on a wide range of cloud providers, and monitor them. You will create Docker containers for your microservices and scale them. Finally, you will deploy your microservices in OpenShift Online.

Understanding monitoring

This section will give an overview of what monitoring actually is and why it is important for delivering a quality production service. We will learn what alerting can do, and how we can use it effectively. Then, we will learn about how we can recover from failures. Finally, we will build a small microservice that will eventually fail, and we will use this to cover more topics in this chapter.

What is monitoring?

The best way to understand and react to failures in a production-ready system is to know what is actually happening. For this, we have to monitor our microservices. Microservices are a complicated set of software, from the code that we write to the libraries that we use, and they utilize, directly...
