Serverless architectures streamline application development by eliminating the need for server management. This approach allows developers to focus on code rather than infrastructure, reducing operational costs and increasing scalability. Cloud providers handle automatic scaling, which means that application resources can adjust in real-time based on demand. With built-in features for authentication and data storage, serverless frameworks enable faster prototyping and deployment. As a result, teams can iterate quickly, delivering features to users without being hindered by the complexities of managing servers or cloud infrastructure.
