For example, you might set up a domain of application server nodes running in a cluster, providing load balancing and high availability. However, you can also achieve the same outcome with a set of standalone application servers.

What differentiates these two scenarios is that when running in a domain, you can efficiently manage your set of servers from a single, centralized unit. On the other hand, managing a set of standalone...
