We are all creatures of convenience. So just think, which package delivery company you would give a favorable review: the one that, though providing package tracking, informs you on what day and within what time frame you’re supposed to expect your delivery to arrive (and even that ends up incorrect due to, say, traffic delays), or the one that actively notifies you that your package is now ‘this many’ stops away from you?
The demand for real-time applications and services is undoubtedly increasing. If your business app or service is customer-oriented, be aware that customers will probably expect a more immediate, real-time experience. And with that, the topic of event-driven architecture increasingly gains strategic importance and hence the interest from companies of all sizes.
