What Are the Components of Event Based Architecture?

Businesses, no matter how big or small, can run into hurdles at any point in the day. However, more companies are recognizing that there are ways to take information from the past and present and fit them to each scenario accordingly. This is because of new technology referred to as event-driven architecture, which allows businesses to take notifications over time to make better business decisions and better assist vendors and customers alike.

Event-Driven Architecture

It’s important to have a proper event channel in place that allows for companies of any size to deal with any series of events throughout a given time span. That’s where event based architecture comes into play. This is a software design pattern that enables an organization to detect important business moments and act on an event queue with information from historical data and an event log, as well as real-time data. Event-driven architecture replaces the traditional “request/response” architecture, needing a reply before moving on to the next task.

Also known as EDA, this software logs data and takes snapshots of current situations from various event sources. This event-driven architecture allows for a true connection between past and present. Event-centric architectures essentially act as a nervous system in the mechanism that it sends out messages. This is carrying messages throughout the business, no matter the type of event or specific task. This form of event stream processing can help to expedite certain processes and make decisions with a better understanding of the why.

Taking Architecture to Task

Event-driven platforms are broken down into access through effectively three roles: event producer, event consumer, and event broker. In certain cases, a single event producer and a single event consumer can work directly through the event stream. This is usually brought on by multiple data sources sending out all types of events with one or more consumers interested in specific tasks or even just simple events in a queue. This only happens successfully with the proper framework to understand even the most complex events.

Events can vary depending on the change of state brought on by either sender, mediator, or vendor. One example is resetting a password on a website, triggering an event message through automation that sends an e-mail to a user to change up the password. This event-based technology can also be used to track packages for delivery. Event logs can monitor the where and when of each package with each new order that comes in for an online retailer. Online banking applications may even use this to monitor unauthorized access to prevent fraud in certain circumstances.

Understanding Events

An event is defined as a change of state within an architectural pattern. This is a situation that can pop up throughout an event channel, which will, in turn, trigger a message by being produced, published, detected, or consumed. The event is the actual occurrence, while the message is the traveling notification that relays the occurrence through an EDA platform. Wherever the issue arises, it will likely trigger one or more actions or processes in response to that new event. With proper design by an architect, the company will be able to demonstrate resiliency against any magnitude of events.

When an event notification is sent, the system captures an instance occurring, like a state change, sending the reply to wherever the request came from. The application form within the architecture that received that alert from the message queue can either respond or wait to respond until the message is read or a change occurs. With proper event-driven architecture, your business will be able to handle an endless stream of events, and brace for growth along the way.
