Chapter 5. Configuring a WildFly Domain

Now that we have looked at the core configuration of the server, we can move on to the domain configuration. Shaping a server domain is a key task for administrators who want to efficiently coordinate a set of application servers. In this chapter, we will describe all the steps necessary to create and configure a domain of WildFly instances.

As we will see shortly, the configuration of subsystems does not vary between standalone and domain configuration. To work with domains, we also need to learn about the domain controller and host controller configurations. These are responsible for handling and coordinating the lifecycle of applications across several servers.

So, in this chapter, we will cover the following topics:

• Introduction to the WildFly domain
• How to configure the domain components
• The criteria to choose between a domain and a standalone server
• Introducing WildFly domain mode
