What do you need to set up a cluster with JBoss?
The simplest way to start a JBoss server cluster is to start several JBoss instances on the same local network, using the run -c all command for each instance. Those server instances, all started in the all configuration, detect each other and automatically form a cluster.
What is JBoss JGroups?
JBoss uses a tool called JGroups to enable peer-to-peer communication between nodes. JGroups is a toolkit for reliable multicast communication. It uses existing network infrastructure and protocols to transmit multicast messages that are reliable because receivers can request retransmission of lost packets of data.
What is JBoss EAP and JBoss AS?
JBoss EAP is the name for the Java EE application server that Red Hat produces and supports. The latest version is 6 at the moment and this implements Java EE 6. JBoss AS/WildFly is the name for the community project that you can test. This community project will eventually become JBoss EAP.
Can JBoss run on AWS?
You can launch a JBoss EAP instance on Amazon EC2 using the EC2 console. You can also launch an instance using the AWS Command Line Interface. See AWS CLI for more information about AWS CLI.
Is JBoss still supported?

Is JBoss EAP a Web server?
JBoss EAP includes a flexible web server, Undertow, as well as enterprise features such as failover, clustering, caching, intelligent load balancing, and distributed deployment performance-tuned for highly transactional applications.
Is JBoss EAP open source?

Which component of JBoss EAP does clustering?
The most common clustering architectures in use by JBoss are client-side interceptors also known as stubs or smart proxies and external load balancers. Both the architectures of JBoss AS uses load balancing policies to establish which server node should send a connection to which another node in a network.
Can you create a cluster in standalone mode?
As previously mentioned, to get clustering capabilities you need to use either the ha profile or the full-ha profile. We will stick with the ha profile for now. In standalone mode, this means that your configuration file is meant to be the one named standalone-ha.
What is JBoss standalone mode?
A standalone server instance is an independent process, much like an JBoss Application Server 3, 4, 5, or 6 instance is. Standalone instances can be launched via the standalone.sh or standalone.
What is a cluster of JBoss EAP 6 servers?
Ideally, a cluster of JBoss EAP 6 servers is viewed as a single EAP 6 instance and the redundancy and replication is transparent to the caller. www.redhat.com 4 [email protected]
How does JBoss Enterprise Application Platform work?
The configuration script used in the last section, JBoss Enterprise Application Platform, contacts the domain controller of each of the domains and issues a large number of CLI instructions from a Java interface. The result is that the required server profiles are created and configured as appropriate for the cluster.
How do I cluster a JBoss web server for ha?
The web server itself can be clustered for HA, using one of several compatible load balancing mechanisms. The most flexible is mod_cluster connector, which is tightly integrated with the JBoss Enterprise Application Platform’s container. Other choices include Apache mod_jk or mod_proxy connectors, or the ISAPI and NSAPI connectors.
What is the use of JBoss-CLI-client in EAP 6?
JBoss EAP 6 provides a Java library, packaged in the jboss-cli-client.jarfile, to enable configuration and management of EAP 6 instances through Java. This library is intended for general and broad use and as such, it is fairly low-level and does not add much abstraction on top of native CLI.
