The service that allows you to run code as functions without the necessity of server management is indeed AWS Lambda. This serverless computing service enables developers to execute their code in response to specific events such as changes to data, HTTP requests, or messages from other services. With AWS Lambda, you simply upload your code, define the triggers for when it should run, and AWS takes care of all the infrastructure concerns, including scaling, patching, and managing servers.

This approach allows you to focus on writing your code while AWS handles the complexity of the underlying infrastructure, which is ideal for applications that need to scale or handle sporadic workloads. Moreover, AWS Lambda operates on a pay-as-you-go model, where you only pay for the compute time consumed, making it cost-effective for various applications.

In contrast, services like AWS Elastic Beanstalk involve some server management, allowing developers to deploy applications but requiring them to manage the underlying resources to some extent. Similarly, Amazon EC2 provides virtual servers in the cloud but requires users to manage instances, load balancing, and scaling, which is not the case with Lambda. Amazon Lightsail offers a simplified virtual server setup but does not provide the serverless capabilities that Lambda offers, as it still requires users to handle server
