AWS Lambda is a serverless computing service that allows you to run code without the need to provision or manage servers. This means that you can focus on writing your application code, while AWS takes care of the underlying infrastructure. When an event triggers your Lambda function, AWS automatically runs your code in response to that event, scaling the resources as needed and handling the execution environment.

The serverless architecture provided by Lambda allows developers to build applications that can scale easily and respond promptly to various triggers, such as changes in data or user requests, without the overhead of maintaining server instances. This efficiency is especially beneficial for developers looking to build microservices or automated workflows, as they can deploy their applications rapidly without worrying about server management tasks.

In contrast, provisioning databases, monitoring resource usage, and setting up network security pertain to different services offered by AWS. These actions are essential for managing cloud resources but do not align with the core functionality of AWS Lambda, which is specifically tailored for running code in a serverless environment.
