What is the main function of AWS Lambda?

The primary function of AWS Lambda is to enable serverless computing, which allows users to run code without the need to manage the underlying infrastructure. This means that developers can focus solely on writing the code for their applications without worrying about server provision, scaling, or maintenance. AWS Lambda automatically handles the execution of the code in response to events, automatically provisions the compute resources required for the specified runtime, and scales seamlessly as needed based on the volume of requests. This serverless model promotes cost efficiency, as you only pay for the compute time your code consumes, rather than for pre-allocated server capacity. This approach facilitates rapid development and simplifies deployment, making it an essential service for building modern applications.
