OutSystems Event-Driven Architecture: Say bye to brittle

Traditional architectures are built of tightly-coupled services, which means that a single point of failure can disrupt an entire system. This impedes reliability and responsiveness, while also making it harder to scale or adapt to changing business needs.

In a conventional system, actions are driven by client requests that require a response from the server. As requests increase, server response time decreases. In an EDA-based system, however, actions are driven by events that are processed independently of each other and in parallel, making it easier for the system to handle high volumes of activity.

When building complex workflows within monolithic structures, there is no way to avoid intricate dependencies. EDA breaks down complex workflows into modular, independently deployable services, eliminating dependencies and making way for less brittle, more resilient logic.

In conventional request-driven models, actions only occur after a response is requested and then received from a server, which makes both near real-time and asynchronous communication difficult. In EDA, actions occur automatically based on detected events, which can be any significant occurrence or change in state.

Developers using traditional approaches to EDA have to write complex custom code for event-related tasks, which takes longer, requires expertise, and leaves room for error. With OutSystems, your dev teams are given the unified tool they need to easily take advantage of all the benefits EDA has to offer.
