| <title>Apache Synapse - The Lightweight ESB</title> |
| </properties> |
| <body> |
| <section name="Apache Synapse Enterprise Service Bus (ESB)"> |
| <p> |
| Apache Synapse is a lightweight and high-performance Enterprise Service Bus (ESB). |
| Powered by a fast and asynchronous mediation engine, Apache Synapse provides |
| exceptional support for XML, Web Services and REST. In addition to XML and SOAP, |
| Apache Synapse supports several other content interchange formats, such as plain |
| text, binary, Hessian and JSON. The wide range of transport adapters available for |
| Synapse, enables it to communicate over many application and transport layer |
| protocols. As of now, Apache Synapse supports HTTP/S, Mail (POP3, IMAP, SMTP), |
| JMS, TCP, UDP, VFS, SMS, XMPP and FIX. |
| </p> |
| <p> |
| Apache Synapse is free and open source software distributed under the |
| <a href="http://www.apache.org/licenses/LICENSE-2.0">Apache Software License 2.0</a>. |
| The latest version of Synaspe is <a href="download/2.1/download.cgi">v2.1</a>. |
| This release comes with a horde of new features, bug fixes, performance and |
| stability improvements. |

| <section name="High Level Architecture"> |
| <p> |
| Apache Synapse is designed to be lightweight and fast. The non-blocking HTTP |
| transport, the multi-threaded mediation engine and the streaming XML infoset combine |
| to ensure that Synapse can mediate very high volumes of messages through the service |
| bus with minimum delay and resource usage. Synapse also comes with comprehensive |
| logging capabilities, statistics collection and JMX monitoring support which are |
| crucial in production deployments. |
| </p> |

| <p> |
| Synapse uses Apache Axis2 as the underlying Web Services engine. Therefore it |
| has outstanding support for Web Services and related standards such as SOAP and |
| WSDL. Tried and tested Axis2 modules like Apache Rampart and Apache Sandesha2 can be |
| used with Synapse with no configuration overhead. Using such external modules, |
| Apache Synapse supports a range of Web Services standards including WS-Security and |
| WS-Reliable Messaging. Synapse also makes use of the Axis2 clustering framework to |
| provide enterprise grade clustering support. |
| </p> |
| <p> |
| Synapse is configured using a simple, XML-based configuration language. The |
| configuration language and the related functional components are designed with SOA |
| best practices in mind. It is trivial to store configuration fragments in an external |
| SOA registry and import them to the mediation engine on demand. Synapse ships with a |
| large collection of mediators that can be used to implement even the most complex |
| enterprise integration scenarios. If necessary, the mediation engine can be extended |
| by developing custom mediators using Java or your favorite scripting language. |
