Which service provides event-driven serverless computing?

AWS Lambda is the service that provides event-driven serverless computing. It allows developers to run code in response to events, such as changes in data, system state, or user actions, without the need to provision or manage servers. This means you can focus on writing the code rather than worrying about the infrastructure required to run it.

With AWS Lambda, you can set up triggers from various AWS services, such as S3 (for file uploads), DynamoDB (for data updates), or API Gateway (for HTTP requests), enabling a highly scalable way to execute code in response to actual events. This serverless approach means you only pay for the compute time you use, making it a cost-effective solution for many use cases, such as data processing, IoT backends, and automated workflows.

In contrast, the other services offered in the options are not designed specifically for event-driven serverless computing. For instance, Amazon EC2 provides virtual servers for running applications but requires management of the underlying infrastructure. Amazon RDS offers managed relational database services, and while it can be part of an event-driven architecture, it does not inherently provide serverless capabilities. Amazon S3 is primarily a storage service and, while it can trigger events that could invoke Lambda functions
