Presentation Transcript

  1. What Is ActiveMQ ? ● An Open Source Message Broker ● Written in Java ● Apache 2 License ● Implements a full JMS client ● Scales via a Network of Brokers ● Supports Message Persistence via disk or database

  2. ActiveMQ Protocols Supported ● AMQP ● RSS and Atom ● AUTO ● Stomp ● MQTT ● WSIF ● OpenWire ● WS Notification ● REST ● XMPP Binary protocols like OpenWire are faster than text based protocols like Stomp.

  3. ActiveMQ Containers ● OSGi Integration ● Axis and CXF Support ● Resource Adapter ● BlazeDS ● SJSAS with GenericJMSRA ● Geronimo ● Spring Support ● Glassfish ● Sun JNDI ● JBoss ● Tomcat ● J2EE ● WebLogic Integration ● JCA Container ● zOS ● JNDI Support

  4. ActiveMQ Libraries ● Node.js ● .NET ● Perl 5 ● C++ ● Pike ● Erlang ● Python ● Go ● Racket ● Haskell ● Ruby on Rails ● Jekejeke Prolog ● Tcl/Tk ● NetLogo See the following page – activemq.apache.org/cross-language-clients For a huge list of code samples

  5. ActiveMQ AJAX ● Asynchronous Javascript And Xml Mechanism ● Used for real time web applications ● Uses an AMQ AjaxServlet ● Currently uses three adapters for comms – jQuery, Prototype, and Dojo ● Can filter received messages via use of selector

  6. ActiveMQ Artemis ● A set of Plain Old Java Objects ( POJO ) ● Ultra high performance persistent journal ● Currently two API's – Core client API , JMS 2.0 client API ● Offers protocols – AMQP ,OpenWire ,MQTT ,STOMP ,HornetQ ,Core

  7. ActiveMQ Artemis Architecture

  8. ActiveMQ JMS to JMS Bridge ● Allows bridging to other JMS providers ● Needs JMS 1.0.2 + ● Bridge locally or remotely ● Should consider Apache Camel First ! – Enables flexibility – Content based routing – Allows alternatives to JMS

  9. ActiveMQ WebSockets ● From v5.4.0 ActiveMQ supports HTML5 WebSockets ● Browser to Broker asynchronous messaging ● Use Stomp for text or JSON ● Use MQTT ( v5.9.0 ) for binary ● Broker must be on same host as web client

  10. Available Books ● See “Big Data Made Easy” Apress Jan 2015 – ●See “Mastering Apache Spark” Packt Oct 2015 – ●See “Complete Guide to Open Source Big Data Stack “Apress Jan 2018” – – ● Find the author on Amazon www.amazon.com/Michael-Frampton/e/B00NIQDOOM/ – ●Connect on LinkedIn www.linkedin.com/in/mike-frampton-38563020 –
