GlassFish is an open-source implementation of the Java platform. It supports several technologies including, EJB, JPA, JSF, JMS, RMI, JSP, servlets and allows developers to create portable and scalable applications.
GlassFish cluster is a collection of GlassFish Server instances that share the same applications, resources, and configuration information. It allows you to monitor all instances in a cluster from a single host. It is designed for failover, scalability, and load balancing.
