Whether you're building a new application or adding new features to an existing application, it is worthwhile to reflect on the structure and design of what you're building. Not only does app architecture make the difference between a good app and an excellent app, but it can also either contribute to technical debt or mitigate it.
Moreover, since your application's architecture will affect how you will be able to adapt and update your application in the future, this decision carries long-term implications and strategic significance.
That is why we want to discuss event-driven architecture in this blog post. Specifically, what makes this architecture model unique, how it works, and what advantages and opportunities it provides. Finally, we want to explain why the cloud computing industry is so excited about pairing this architecture model with serverless technology.
As the name suggests, event-driven architecture makes your whole application design event-centric.
Event-driven architecture is best understood as the composition of loosely-coupled services that handle events in real-time.
There are three defining components to event-driven architecture:
Event-driven architecture is an excellent model for creating robust and resilient apps. This model provides developers a great level of flexibility when testing and creating new services and apps. Moreover, by processing events as they occur, this architecture aligns your app with the real-world, which improves your user experience and increases your competitive edge.
Serverless computing and event-driven architecture are on the rise. These concurrent trends are propelling developers and businesses forward as they enable developers to focus on improving their application’s flexibility and performance all while dramatically optimizing a firm’s IT costs and the application’s time-to-market.
In event-driven architectures, events trigger applications. Adopting serverless simplifies app management, which results in signifiant cost and complexity reduction when using event-driven architecture. Since your IT teams are no longer burdened with managing and scaling your underlying infrastructure, they are able to redirect their focus to work on more critical tasks to developing and improving your business. By eliminating this operational complexity, your business gains significant competitive advantage.
An additional benefit to this pairing worth mentioning is scaling. The decentralized and loosely-coupled nature of modern event-driven architectures makes it easier than ever to scale your app, and since serverless platforms are autoscaling by design, your teams will never have to worry about scaling again.
With serverless platforms, you are only charged for the computing time and power your application uses. By combining the event-driven model with serverless platforms, you optimize your cloud budget by only paying for the resources that are necessary to meet your application’s demand.
Overall, pairing serverless technology with event-driven architecture offers businesses a way to optimize their cloud costs without compromising on performance and lets developers no longer worry about maintaining or scaling the underlying infrastructure that powers their apps.
