Businesses in this modern era know the importance of being able to make better decisions in real-time. Event-driven architecture is helping organizations of all sizes better understand their inner workings. Also known as EDA, this software design pattern enables companies to detect important business moments and act on them in real-time. This is helping companies break away from the past “response-reply” system that required a waiting period before moving on to another task. Here are just some of the situations that call for event-driven architecture.
1. Password Resets
Events are defined as a state change of a key business system. Event-based architecture is a software platform that addresses a series of events that creates a message by being produced, published, detected, or consumed. In an event-driven architecture, an event will likely trigger one or more actions or processes in response to its occurrence. One of the common situations where EDA is present and you may not even realize is when a user sends a website a request to reset their password.
An event notification is sent to that user’s email, giving the customer a link to reset their password. With EDA, that request to reset does not halt the stream of events. Applications are able to move on to the next task in the event queue, not having to wait idly by for that customer to change their password as seen in a “response-reply” setting. Applications built around an event-driven architecture enable more agile, scalable, contextual, and responsive digital business for any application state.
2. Keeping Track of Inventory
One of the great benefits of event stream processing is the ability to take on any query in real-time or with the most immediacy possible. In the event-driven model, data is still important, but the events become the most important component. With EDA, the priority is to make sure you respond to events as they happen. This is bettering business logic when it comes to evaluating inventory. This architecture pattern tracks sales as they occur, allowing businesses to be able to keep track of trends and what’s driving their customer base.
With this type of event, organizations are able to monitor issues within the supply chain. For example, a retailer may see an influx in sales of certain appliances. And need to be sure that the manufacturer is able to keep up with the request. However, EDA allows the business to focus on other point integrations that are drawing in or hindering sales. This microservice architecture is able to handle a queue of specific tasks and complex events without having to wait on one issue to be addressed with a single vendor.
3. Monitoring Fraud
EDA affords organizations resiliency for event producers, event brokers, and event consumers alike. If you are a retailer, you might be collecting all of the purchases that are happening at all of your stores. Business users are feeding them into an EDA that is watching for fraud, sending them to credit card processors, or whatever actions need to happen next. In the financial sector, banks and other outlets can monitor accounts for unauthorized attempts to access funds. Locking the accounts and sending out notifications to customers to alert them to the issue.
With an event queue, a data architect is not hindered by any external sources or having to await a reply. This allows for constant monitoring for any potential fraud based on real-time information through stream processing. While these are just a few situations that call for EDA. There is much more EDA can accomplish for businesses of any size and in any industry.
