Event Driven Architecture (EDA) is a modern software architecture paradigm that has evolved from microservices architecture. It is gaining popularity due to its platform-agnostic nature and scalability, making it suitable for a wide range of applications. EDA is particularly effective in building highly scalable systems, as it allows for asynchronous communication between components through events.

In EDA, events are used to trigger actions and facilitate interactions among various services. This architecture supports the implementation of events that span multiple services, providing eventual consistency and enabling applications to maintain materialized views. The architecture can be organized into different topologies, such as the Mediator and Broker topologies, which help in orchestrating events and managing communication between components effectively ¹⁴⁵.

Overall, EDA is a powerful approach for developing applications that require high scalability and responsiveness, making it a popular choice in today’s software development landscape.
