Event-Driven Architecture (EDA) and APIs (Application Programming Interfaces) offer distinct approaches to system design. EDA uses asynchronous communication where components emit and react to events, making it highly scalable and suitable for real-time applications like IoT and financial transactions, though it can be complex to manage. In contrast, APIs typically use synchronous communication with a request-response model, resulting in tighter coupling but easier implementation, ideal for CRUD operations and microservices. While EDA excels in scenarios requiring real-time processing and scalability, APIs are better suited for web services and applications needing straightforward, synchronous interactions. Understanding these differences can help you choose the right architecture for your project’s specific needs. In this talk I will highlight how EDA’s real-time processing can revolutionize industries by enabling instant data analysis and decision-making. Imagine the power of a system that can react to events as they happen, driving innovations in fields like IoT and financial services. You will learn the simplicity and ease of use of APIs, which can significantly speed up development and integration processes, allowing businesses to bring new features to market faster than ever before. I will share real-world examples to make these concepts tangible: how EDA powers high frequency trading platforms, ensuring transactions are executed in milliseconds, or how APIs streamline interactions in popular web services, making our daily digital experiences seamless. When I illustrate these practical applications, you’ll not only informed but also take inspired actions and learn transformative potential of choosing the right architecture for your projects.”
