Why Event-Based Architecture Works: The Value of Event Notifications

As we continue hurtling through the process of digital transformation, responding to requests in real-time is becoming more and more important. Whether you look at company needs or the use between individuals, it is clear that event-based styles are preferred over others. We’ve already discussed the overall shift from RESTful to event-based and why this has taken place.

Notification patterns are generally liked because they are comparatively easy to include in an existing RESTful system and provide a number of choices for execution as well as consumption. This article examines the simplest of the four event styles: event notifications and sees how it can improve RESTful processes.

What Does an Event Notification Consist Of?

To put things very simply, event notifications are alerts from a system. They are usually simple threads that announce actions or events in the domain. They are general messages you see on your phone or desktop every day. These include notifications like “The device memory is almost filled”. Or the one you’ve been ignoring for weeks now: “Your system requires several updates”.

Event notifications used in machine-to-machine API interactions typically carry a simple message. One that a person or another device wants to know about or is tasked with dealing with. That’s one of the main elements of ENs: they have a target audience.

Furthermore, these notifications don’t carry too much information. They are short and simple without any details. To get around this, event notifications often include links that provide more detailed information. So, along with a descriptive string, they usually contain a link to another source. 

Last but not the least, event notifications can also contain a date-time stamp to add some background to the message. This helps if, for example, you have to collect or store the messages for later. 

Why Are They Useful to Businesses?

Although event notifications are pretty simple, they can have a major effect on your software architecture. This goes for both the client-side and server-side applications. Anyone who owns a device has been on the receiving end of these notifications. Take online banking; you are notified whenever any money is added to or removed from your account. 

A solid example of client-side event notification is the use of desktop and mobile pop-up or push notifications. These are short messages that remind you to check your email, notify you about someone’s birthday, or read an article that you’ve been saving up.

On the client-side, they are frequently used as nudges that promote user interaction and engagement. Adding them to your own client-side applications can improve user experience without adding too much strain on your system.

On the other hand, the most common instance of server-side notifications is the use of tracking and logging messages for your services. Most platforms have some system of collecting key actions within services such as user logins, shopping cart check-outs, and submitted forms. 

These actions can help you scope out the conditions of your business. A shopping cart that has been checked out can tell you that business is going well.  Many event notifications like these are alerts and can be displayed on live dashboards at certain places within the company to monitor the health and welfare of the IT side of the business in near-real-time.

Server-side alerts and client-side nudges are great ways to encourage the client and business to engage with each other. This tends to mutually benefit both parties without exerting the system or creating the need for restructuring everything. It is also serving as a gentle reminder to the client without annoying them. 

Best of all, you can sometimes treat server-side alerts as an add-on to existing systems without having to rewrite the code. Client-side event notifications usually need additional coding so that the client apps can listen to and respond to the messages as soon as they show up. 

Wrapping Up

As you continue to enhance additional support for Event-based interactions to your platform, event notifications are a good place to begin. They often need limited investment and can give you the necessary business feedback. Because event notifications are mostly just alerts and nudges, you can add them to your infrastructure with minimal tweaking without demanding huge changes to your data models, program interfaces, or workflow processes. 

So if you are looking for better ways to engage with your clients, consider adding event notifications to your services. They are a great way to observe the state of the business without needing many resources. And your customers may just love the little reminders and interactions this will give them!
