Scala Reactive Programming

By: Rambabu Posa

Overview of this book

Reactive programming is a scalable, fast way to build applications, and one that helps us write code that is concise, clear, and readable. It can be used for many purposes such as GUIs, robotics, music, and others, and is central to many concurrent systems. This book will be your guide to getting started with Reactive programming in Scala. You will begin with the fundamental concepts of Reactive programming and gradually move on to working with asynchronous data streams. You will then start building an application using Akka Actors and extend it using the Play framework. You will also learn about reactive stream specifications, event sourcing techniques, and different methods to integrate Akka Streams into the Play Framework. This book will also take you one step forward by showing you the advantages of the Lagom framework while working with reactive microservices. You will also learn to scale applications using multi-node clusters and test, secure, and deploy your microservices to the cloud. By the end of the book, you will have gained the knowledge to build robust and distributed systems with Scala and Akka.

Benefits of microservice architecture

When we use the microservice architecture to develop our system, we will get the following benefits:

  • More reusability
  • Loose coupling between services
  • We can deploy and scale them independently
  • We can use different technology stacks to develop different microservices
  • Easy for developers and QA to understand their services
  • Clear separation of concerns
  • Does only one thing very well
  • Ease of testing and maintenance
  • Fault isolation
  • High Cohesion, Reliable, and more Resilient
  • Very flexible
  • Requires less deployment time
