Becoming event-driven sounds like the logical next step: real-time visibility, faster response, tighter integration. The promise is appealing, no? But turning that vision into reality is another story. Where do you start, with technology, operating model, or mindset?
Many soon discover that event-driven design reshapes everything. Data ownership becomes decentralised, monitoring grows complex, and governance feels like chasing a moving target. Scaling up amplifies both the benefits and, if poorly governed, the costs as well. The question then becomes: what is the return on all that investment? Does the model actually reduce cost over time, or simply move it elsewhere? And when does ROI start showing, during scaling or only once operations stabilise?
The goal remains clear: systems that react faster, stay reliable, and create measurable value at speed. But the path there is not. Let’s explore what it means to build event-driven architectures, what challenges surface at scale, and what financial outcomes they truly achieve. A closed conversation for those aiming to prove that responsiveness can also be sustainable.
