This document discusses deploying the open source messaging platform Red Hat JBoss A-MQ in a high availability environment. It provides an overview of JBoss A-MQ's master/slave architecture using shared or replicated storage for fault tolerance. It also demonstrates configuring a fabric-based network of brokers for scalability and client-side load balancing and failover.

Agenda
● JBoss A-MQ High Availability Overview
● Demonstration of a fabric-based network of
fault-tolerant (master/slave) brokers

What is JBoss A-MQ?
Open
Scalable
Reliable
*assuming you already know it does reliable messaging

6. 6 RED HAT JBOSS A-MQ
JBoss A-MQ :: Open
● Open Source
– Apache Software License 2.0 licensed
– Based on very popular Apache ActiveMQ
● Open Protocol
– AMQP 1.0, MQTT, STOMP, OpenWire, …
● Open Language (Polyglot)
– Client native languages: Java (JMS), C/C++, .NET
– STOMP clients: Ruby, JavaScript, Perl, Python, PHP,
ActionScript, ...

7. 7 RED HAT JBOSS A-MQ
JBoss A-MQ :: Scalable
● Vertical Scaling
– Only limited by I/O, compute, and I/O resources, …
● Horizontal Scaling
– Network of Brokers (Clustering / Federation)
– Fuse Fabric (https://github.com/jboss-fuse)
● Central configuration management and provisioning
● Client-side discovery, load balancing, and failover

9. 9 RED HAT JBOSS A-MQ
JBoss A-MQ :: Reliable
● Persistent Messaging
– Store on File system or RDBMS
– Survive restart, and process failure
● Master / Slave
– Lock manager
– Shared Storage - SAN/GFS2 or NFS v4 or RDBMS
– Replicated - Block or RDBMS replication
● Managed
– Red Hat Cluster Suite
– Shared or Replicated storage

Client Connection URI
● Static
– tcp://<host>:<port>?<connection options>
– Simple, but no reconnection on failure
● Failover Transport
– failover:(tcp://<host>:<port>,tcp://<host>:<port>,...)
– Reconnect on failure
● Fabric Discovery
– discovery:(fabric://<group name>)
– Reconnect of failure
– Coordinates with Fabric Registry

15. 15 RED HAT JBOSS A-MQ
Red Hat High Availability Add-On
● Smarter failure management
– N+1 failover architecture
– Restart on node first, then failover to back node
– More sophisticated detection than just process failure
● RHEL only
● Complements JBoss A-MQ HA capabilities
