Event-Driven Architecture

Event-driven architecture is a mechanism for services in a computer software system to communicate with each other in a seamless manner using messages, also known as events or triggers.

Events are fired as a way for services to execute a task and notify another service to enable a complex system to achieve the sequence of tasks it has in an established way. For this kind of architecture, usually, there has to be much planning around capacity and load for sizing, followed by determining the sequence and implementing it.

Messaging has always been present as part of the infrastructure for more asynchronous tasks, such as moving data from point A to point B, indexing for search, and passing messages in microservices.

However, in the current time and the era of data and scalability, we see a shift, and new tools are developed for achieving moving data at scale in a reliable and fast manner.

In this article, we discuss Kafka as an example of an open-source platform that enables people to implement an event-driven architecture. The idea here is continuous execution and implementation of a sequence of tasks reliably as quickly as possible. We will start by explaining some examples, terminologies,…
