Event Driven Architecture - MeshU - Ilya Grigorik - Presentation Transcript

  1. Event-Driven Architectures Ilya Grigorik CTO / AideRSS Event-Driven Architectures http://bit.ly/eda-mesh @igrigorik #meshu #eda
  2. Apr 7th launch: Bestest Blog discovery! Event-Driven Architectures http://bit.ly/eda-mesh @igrigorik #meshu #eda
  3. • Request, Response Cycle • Event Driven Architectures • Cloud Computing • Real-time Web! Fully buzzword • XMPP & AMQP compliant! • Example Questions & The slides… My blog Comments Event-Driven Architectures http://bit.ly/eda-mesh @igrigorik #meshu #eda
