Which AWS service would you use for serverless computing?

AWS Lambda is the appropriate choice for serverless computing because it allows developers to run code without provisioning or managing servers. With Lambda, you can execute functions in response to various events, such as HTTP requests, changes in data, or messages from other AWS services, which simplifies the process of building scalable applications. This service automatically manages the underlying infrastructure, scaling the compute power as needed based on the volume of requests, thus enabling users to focus on writing application code rather than worrying about server maintenance or capacity planning.

In contrast, Amazon EC2 provides virtual servers for computing needs but requires management of the underlying instances, making it a more traditional computing model rather than serverless. Amazon RDS is a managed relational database service which handles database tasks but does not align with serverless principles. Lastly, Amazon CloudFront is a content delivery network service that speeds up the distribution of web content and does not directly relate to serverless computing. Therefore, AWS Lambda stands out as the definitive service designed explicitly for serverless applications.
