A managed server is another instance of your WebLogic server that runs on the JVM and has a self-managed specific configuration. A managed server is used to deploy the components of Java-like EJB applications, Web applications, JMS applications, and other related web services. A domain may or may not have a managed server and the count can go up to N number of managed servers. Until and unless the servers are in a cluster, a managed server always operates independently.
