In this fast-paced digital world, organizations are relying on event-driven architecture (EDA) that facilitates real-time responses, flexibility, and scalability in their business systems.

To understand EDA is a software design practice that structures a system’s segments to respond to, produce, and process events. For instance, any event creates a significant change in state within a system that is further triggered by external characteristics, such as user activities, sensor inputs, and other systems.

The rise of microservices is one cause for the prompt adoption of event-driven API (EDAs) management. These EDAs are centralized to this architecture, allowing data exchange through different events that aid in optimizing performance, ensuring scalability, and maintaining seamless integration between various services and applications.

In this article, we will explore the top five EDAs that enable developers and businesses to stay ahead of the evolving landscape of real-time interactions.

Apache Kafka

The first event-driven API on our list is Apache Kafka, which is an open-source, distributed streaming solution that allows developers to publish, subscribe to, and process streams of events in real time. Kafka has excelled in handling large data sets in real-time, even in low latency, which makes it an ideal solution for messaging and event sourcing. This API is also known for its high fault tolerance via its distributed architecture, guaranteeing that even in the case of node failure, data is not lost. However, Kafka lacks built-in authorization for features such as message filtering or priority queues, which are essential in some event-driven use cases and can be a major drawback while setting up distributed systems. Even though Apache Kafka is open-source and free to use, it has a paid version, which is called Confluent Cloud, that offers a fully managed data transfer service with pricing starting at $0.10 per GB for storage.

Gravitee

Even though Gravitee is an open-source API management platform, it offers event-driven API capabilities that support synchronous and asynchronous API lifecycles and security. Gravitee is known for its user-friendly interface, which simplifies the API management process, allowing developers to deploy only the components they need and reducing unnecessary complexity. Apart from that, Gravitee reinforces event-driven protocols such as WebSockets and Server-Sent Events (SSE), making it an ideal choice for businesses transitioning into EDA. However, Gravitee struggles with performance issues, particularly with high-throughput events, which eventually lags in documentation. For additional enterprise editions, Gravitee charges $1,500 per month; however, the pricing may increase on add-on custom services and API traffic volume.
