Why Being Reactive is Good

Published October 22, 2015 in Programming

One of the more difficult aspects of systems architecture is finding concrete terms to describe desirable characteristics that everyone understands. Reactive was one of those terms until two years ago, when the Reactive Manifesto was released. Today, over 12,000 people have signed the online document and participated in its evolution. But what does it mean, and how do the principles described by it help developers engineer systems that are elastic, resilient and responsive to users in the face of bursty load and random/unknown failures? We will discuss these topics, as well as clearly discuss the concepts of asynchronous tasks, non-blocking threads, concurrency issues and parallelism.

The goal of this talk is to frame the term reactive in a positive light, because when it comes to building real-time systems, being reactive is good.
