A key benefit of using serverless architecture is its ability to streamline application deployment and scaling without the need for server management. In serverless computing, developers focus solely on writing code while the cloud provider handles the infrastructure. This approach reduces operational costs and increases development efficiency, as resources are allocated dynamically based on demand. Serverless architecture promotes a pay-as-you-go model, enabling businesses to scale applications seamlessly while optimizing performance. This flexibility is particularly advantageous for applications with variable workloads.
