What Is Event-Driven Architecture?

Life has a certain ebb and flow to it. As humans, we usually function under the cause and effect mentality. If you do this thing, it will probably cause me to act in this certain way. If you ask a question, I’ll give you an answer. If you give me a hug, I’ll hug back, but if you insult me, I may start to cry. Cause-and-effect moments constitute your entire life and these are usually immediate responses. You don’t wait three to five business days for a response when you’re in the middle of a conversation. And you don’t need to request a certain thing happen to continue with what you’re doing. Now, shouldn’t that be how businesses operate too?

For years, business operating systems have revolved around request/response architecture pattern. A simple event would trigger a state change and then a long stream of events that happened in a precise, unchangeable order. But as the world evolves and people demand immediate service, isn’t it time for an event processor that can keep up? This is where event-driven architecture is changing the game in terms of real-time communication during the business process. In this article, let’s break down exactly what is event-driven architecture and how it can best serve you and your business.

Defining Event-Driven Architecture

Event-driven architecture is a software design where organizations detect event notifications and business moments in real-time so they can react to them immediately. Rather than waiting for data to be processed, you get a notification directly from the event source which will process a new order without waiting for other systems to process. This architecture pattern helps companies read data from external sources and broker them into new complex events without delay. This event flow is a significant change from previous iterations.

To truly understand this kind of event processor, you have to understand where it comes from. In previous workflow examples, movements would focus on resting data and analytics. The focus was on data and processors which took time and allowed your company to remain stagnant. Now, with event-based architecture, every event notification becomes the most important thing. Rather than sitting back and waiting for the data to process events and tell you your next step, you are reacting directly to the event queue. This allows companies to keep track of new events, data changes, and specific tasks as they are happening. Thanks to the law of diminishing returns, if you aren’t on top of a message broker or event stream, you are already behind and could lose customers. Event-based architecture puts you back on track to be the best vendor or mediator in any scenario.

Event Examples

Now, with this architecture pattern, the events aren’t what you would typically think of. We’re not talking about birthday parties and networking meetings. Business events refer to any number of moments that impact your business. Maybe the initial event is someone visiting your site for the first time. A complex event may be someone customizing an order for their own business. Any number of business transactions qualify for your event log. Whenever someone logs into your site, creates a new password, completes a purchase, or abandons their cart, you’ll get an event message. This will then set off a sequence of events that naturally follow the logic flow of any transaction.

Individuals Involved

As with any business entity, there are many players involved in daily transactions. With the event stream processing, you may encounter a seller, broker, and customer. Each category will use this software differently. Maybe you need to message topics to more potential clients or connect your customers to other channels. Whatever your needs, simpler event channels will help you get the job done.
