| h2. Introducing ActiveMQ |
| |
| Apache ActiveMQ is the most popular and powerful open source messaging and Integration Patterns provider. |
| Apache ActiveMQ is fast, supports many Cross Language Clients and Protocols |
| and many advanced features while fully supporting JMS 1.1 and J2EE 1.4. Apache ActiveMQ is released under the Apache 2.0 License |

| h3. Using ActiveMQ from ServiceMix |
| |
| To start using ActiveMQ from your code, simply get a hold of the connection pool declared in the activemq-broker.xml file. |
| If you want to use ActiveMQ as a JBI component, configure servicemix-jms. You can also utilize ActiveMQ from Camel via the |
| camel-jms component. |
| |
| h3. When should I use ActiveMQ? |
| Whenever you have a unit of work or payload that you could process asynchronously, you would like to have multiple recipients, |
| concurrent competing recipients to scale or leverage multiple processing units. If you want to spread load across multiple |
| system boundaries. You want to cluster or provide fail over and messaging security, you have long running flows. |
| |
| In any of these instances it would be strongly suggested you evaluate what a scalable and secure messaging solution can bring to the table. |
| |
| h3. Common use cases |
| Integration with other systems, since you can pass messages in and out of ActiveMQ from pretty much any programming language |
| it is very simple to start integrating heterogeneous environments. |
| |
| Providing an event driven architecture. You can develop your solutions based on actions as opposed to looking for data or |
| relying on completely synchronous behaviour. |
| |
| Providing infrastructure for messaging across large distances, leverage the network connectors and broker networks to integrate |
| for example geographically different data centres. |
