Overview of this book

For a programmer, writing multi-threaded applications is critical as it is important to break large tasks into smaller ones and run them simultaneously. Akka is a distributed computing toolkit that uses the abstraction of the Actor model, enabling developers to build correct, concurrent, and distributed applications using Java and Scala with ease. The book begins with a quick introduction that simplifies concurrent programming with actors. We then proceed to master all aspects of domain-driven design. We’ll teach you how to scale out with Akka Remoting/Clustering. Finally, we introduce Conductr as a means to deploy to and manage microservices across a cluster.

Refactoring the bookstore for ConductR


With a basic knowledge of ConductR under our belts, it's time to start making changes to the bookstore app to allow it to run in ConductR. We will also use the features of ConductR, namely service location, to complete the full separation of our services. When done, we will have a more loosely coupled set of services representing our bookstore app versus the monolith we were using up until this point. The next sections will break down each of the major things we need to do to get the bookstore app running within ConductR.

Splitting apart the bookstore projects

Coming into this chapter, we allowed the different application modules to have dependencies on each other. We saw this in how the sales-order-processing module had dependencies on inventory-management, user-management, and credit-processing. By having dependencies on these other modules, the sales-order-handling code can make direct actor calls to actors within those modules using messages classes...
