Enabling Akka applications for remoting

Before you enable your application to use remoting, review the different transport protocols that you can use to communicate:

• akka.tcp: This is a remoting protocol that uses TCP as the network protocol backed by the Netty framework.
• akka: This is an experimental UDP-based remoting protocol that uses Aeron as the network protocol.

Note

You can learn more about Aeron at https://github.com/real-logic/Aeron.

We will use akka.tcp as it is the more stable remoting protocol currently. However, Akka plans to deprecate it in favor of akka once this new remoting layer becomes more mature.

Getting ready

To step through this recipe, we need to import the Hello-Akka project; all other prerequisites are the same as before. We need to bring the required dependencies for remoting this time.

How to do it...

For this recipe, perform the following steps:

1. Let's start getting the required dependencies. Edit the build.sbt file and add Akka's remote dependency, as follows:
