The primary advantage of using serverless computing in applications is the reduced operational overhead. With serverless architectures, developers can focus on writing code instead of managing infrastructure. This model allows for automatic scaling based on demand, meaning applications can handle varying traffic without manual intervention. Additionally, it results in cost savings since you only pay for the resources consumed during execution, leading to efficient resource management. Furthermore, serverless computing can accelerate deployment times, enhancing overall development agility and enabling rapid iteration to meet evolving market needs.
