Mastering Akka

By: Christian Baxter

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.

An overview of ConductR


Before we jump into installing and using ConductR, it's important to get at least a basic understanding of what it is and what you can do with it. Armed with that knowledge, we can then start to leverage it to complete the process of separating our application components.

At a high level, ConductR is an application that allows you to deploy, manage, and locate application components across a set of server nodes. You can install ConductR on every server within your infrastructure that you will use to host your application bundles. You can also install a proxy, such as HAProxy, on these machines that ConductR will work with to give transparency to what services are running on what local ports. Communicating to services through a proxy also allows you to start/stop and upgrade individual modules without any service disruption, as long as there are other instances of that service available on other nodes that can be proxied to.

Within the ConductR lexicon, a set of application...
