Serverless & Event-Driven Architectures: Redefining Distributed System Design

Abstract

The rise of serverless and event-driven architectures is changing how we design and implement distributed systems. These approaches eliminate the need for server management and use event-based execution. They create systems that are more scalable, easy to deploy, resilient, and cost-effective. This paper looks at how serverless computing shifts the focus from managing infrastructure to focusing on application logic. At the same time, event-driven models improve responsiveness through asynchronous and independent communication. Together, they enhance the design of distributed systems by increasing fault tolerance, lowering operational costs, and supporting real-time, data-heavy applications. The discussion covers architectural principles, design choices, and new best practices that help integrate serverless and event-driven methods in current distributed computing. Ultimately, this study shows how these approaches lead to next-generation cloud-native systems that are flexible, quick, and tailored for changing workloads.
