WildFly plugin provides WAR deployment and other supporting administrative operations. 
WildFly server runs in two modes

• Standalone
• Domain

Standalone

• In Standalone mode, WildFly runs on single server on a single physical host.
• The server acts as a standalone instance which has both admin and managed server capabilities.

Domain

In Domain Mode, WildFly can be controlled from a single point of control, running across machines(hosts). This single point of control is called Domain controller

• In this Mode:
  • Each host will have one host controller and one or many severs on it.
  • One of the host controller's is defined as Domain Controller to manage all hosts
  • We can form Server Groups, which is a logical grouping of servers across multiple hosts
  • Server Groups provide the ability to perform deployment, undeployment on multiple servers at same time.
