A snag can happen at any time for any business of any size. However, organizations can find ways to comb through these difficulties with greater ease to better their inner workings and their customer relations. This is thanks in part to new technologies that allow for companies to address these issues. This is known as event architecture, allowing businesses to take notifications from various event sources to make better business decisions and assist all parties along a supply chain. Let’s take a closer look at this architecture and some of its examples.

What is an event?


In order to better understand the inner workings of this framework, you must first understand what makes an event. An event is defined as a specific task or change of state within architecture. Any event type can trigger a message that is produced, published, or consumed. The event is the actual occurrence, while the message is the notification that relays the occurrence from an architecture pattern. Wherever the issues arise, they trigger one or more actions in response to the new event.

With proper architect design, a company is able to demonstrate resiliency in the face of any litany of events in any order. When an event notification is sent, the system captures the state change to send a reply to wherever the request came from. The application form within the framework receives the alert from a message queue allowing users to either respond or wait to respond until a message is read. With proper event architecture, an organization of any size can handle an endless stream of events.

Understanding Event Architecture


Handling event messages and application state is all part of a controlled and scalable event-driven architecture. Also known as EDA, this is a software design pattern that allows companies of any size to handle even a complex event. This architecture detects important business moments and acts on an event queue with information from historical and real-time data. This framework replaces the traditional “request/response” architecture, needing a reply before moving on to the next step through logic flow. EDA logs data and takes snapshots of situations from various event sources.

Event architecture allows for a virtual connection between past and present while offering security and scalability to protect both the user and the company alike in a variety of scenarios. Event-centric architecture acts as a nervous system in the mechanism that it sends out messages. EDA carries messages throughout the business, no matter the type of event or the specific task that is being asked through a query. By having this form of event stream processing, organizations can expedite certain processes and make decisions with a better understanding of the here and now.

Examples of EDA


EDA components are broken down into three parts: producer, consumer, and a broker. The broker can be optional, particularly when you have a single producer and a single consumer that are in direct communication throughout different events. For example, a producer that is sending only to a database or event store for analysis needs the producer-consumer interaction as the only way to interact through an event architecture. Most commonly in an enterprise, you have multiple data sources sending out all types of events with one or more consumers interested.

For example, a clothing retailer may collect all of their purchases at stores nationwide into one database to check for fraudulent charges. The company evaluating security and fraud cases will have to act as a broker between the retailer and the credit card company that is processing these charges. This EDA technology is also crucial to evaluate all assets within a supply chain for a manufacturer. This helps businesses to schedule maintenance for equipment while focusing on unnecessary downtime in production and customer service queries.
