It’s Not Just Request/Response: Understanding Event-driven Microservices - Seguridad Mania.com - España y América Latina

Why all of the recent buzz around event-driven architectures? Software solutions have implemented event-driven patterns for some time, using message brokers such as RabbitMQ or ActiveMQ. Use of these message brokers is so ubiquitous that every J2EE platform such as WebSphere or WebLogic embeds one. What is new is that we are reexamining event-driven approaches in the microservices context. On the one hand, microservices don’t change things too much—the scenarios that called for message queuing in the past remain. Where eventing gets really interesting is when we start applying it where we used to use a request/response model. We can turn the processing on its head by propagating events through a network of microservices. Doing so can yield more autonomous microservices and more resilient systems. In this session Cornelia Davis, Sr. Director of Technology at Pivotal will examine this approach, describing the architectural tenets and analyzing the benefits and tradeoffs. At the conclusion participants will have some very concrete techniques that they can immediately put into practice.
