[[gktqx]][[GSQSG00037]][[high-availability-clustering-and-load-balancing]]

High Availability Clustering and Load Balancing
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

GlassFish Server enables multiple GlassFish Server instances to be
clustered to provide high availability through failure protection,
scalability, and load balancing. The subsections that follow provide an
overview of high availability clustering and load balancing for
GlassFish Server.

[[gktob]][[GSQSG00047]][[clusters-of-glassfish-server-instances]]

Clusters of GlassFish Server Instances
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

A cluster is a collection of GlassFish Server instances that work
together as one logical entity. A cluster provides a runtime environment
for one or more Java Platform, Enterprise Edition (Java EE)
applications. A cluster provides high availability through failure
protection, scalability, and load balancing.

A GlassFish Server instance is a single Virtual Machine for the Java
platform (Java Virtual Machine or JVM machine) on a single node in which
GlassFish Server is running. A node defines the host where the GlassFish
Server instance resides. The JVM machine must be compatible with the
Java Platform, Enterprise Edition (Java EE).

GlassFish Server instances form the basis of an application deployment.
An instance is a building block in the clustering, load balancing, and
session persistence features of GlassFish Server. Each instance belongs
to a single domain and has its own directory structure, configuration,
and deployed applications. Every instance contains a reference to a node
that defines the host where the instance resides.

For more information, see the following documentation:

* "link:../ha-administration-guide/nodes.html#GSHAG00004[Administering GlassFish Server Nodes]" in GlassFish
Server Open Source Edition High Availability Administration Guide
* "link:../ha-administration-guide/clusters.html#GSHAG00005[Administering GlassFish Server Clusters]" in
Eclipse GlassFish Server High Availability Administration
Guide
* "link:../ha-administration-guide/instances.html#GSHAG00006[Administering GlassFish Server Instances]" in
Eclipse GlassFish Server High Availability Administration
Guide

[[gktpt]][[GSQSG00048]][[session-persistence-and-failover]]

Session Persistence and Failover
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Storing session state data enables the session state to be recovered
after the failover of an instance in a cluster. Recovering the session
state enables the session to continue without loss of information.
GlassFish Server supports in-memory session replication on other servers
in the cluster for maintaining HTTP session and stateful session bean
data.

For more information, see "link:../ha-administration-guide/session-persistence-and-failover.html#GSHAG00011[Configuring High
Availability Session Persistence and Failover]" in GlassFish Server Open
Source Edition High Availability Administration Guide.

[[gksbz]][[GSQSG00049]][[load-balancing-for-clustered-configurations]]

Load Balancing for Clustered Configurations
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

GlassFish Server supports web server and hardware-based load balancing
for clustered configurations. A load balancer is deployed with a
cluster, and provides the following features:

* Allows an application or service to be scaled horizontally across
multiple physical (or logical) hosts yet still present the user with a
single URL
* Insulates the user from host failures or server crashes when used with
session persistence
* Enhances security by hiding the internal network from the user

Eclipse GlassFish Server is compatible with the Apache HTTP
server `mod_jk` module for load balancing.

GlassFish Server load balancing configurations can vary widely depending
on the needs of your enterprise. For complete information about
configuring load balancing in GlassFish Server, see the following
documentation:

* "link:../ha-administration-guide/http-load-balancing.html#GSHAG00009[Configuring HTTP Load Balancing]" in GlassFish
Server Open Source Edition High Availability Administration Guide
