Kotlin for Enterprise Applications using Java EE

By: Raghavendra Rao K

Overview of this book

Kotlin was developed with a view to solving programmers’ difficulties and operational challenges. This book guides you in making Kotlin and Java EE work in unison to build enterprise-grade applications. Together, they can be used to create services of any size with just a few lines of code and let you focus on the business logic. Kotlin for Enterprise Applications using Java EE begins with a brief tour of Kotlin and helps you understand what makes it a popular and reasonable choice of programming language for application development, followed by its incorporation in the Java EE platform. We will then learn how to build applications using the Java Persistence API (JPA) and Enterprise JavaBeans (EJB), as well as develop RESTful web services and MicroServices. As we work our way through the chapters, we’ll use various performance improvement and monitoring tools for your application and see how they optimize real-world applications. At each step along the way, we will see how easy it is to develop enterprise applications in Kotlin. By the end of this book, we will have learned design patterns and how to implement them using Kotlin.

Application monitoring

Monitoring services is a key aspect in keeping track of system resource usage and the application's health. When the service or application is unresponsive or not working as expected, if the system's CPU usage is high or it is taking too long to respond to a request, monitoring helps troubleshoot issues. Application monitoring helps us understand CPU usage and other system resources. The result of the monitoring can be used to make decisions such as scaling services or notifying system administrators so that they can take appropriate actions.

We will discuss some of the popular monitoring tools to analyze a system's CPU and memory.
