Amazon Lightsail is not a serverless computing service. Amazon Lightsail allows users to manage and control virtual private servers (VPS). The user needs to provision, maintain, and manage these servers. On the other hand, serverless computing, such as AWS Lambda, allows users to run code without provisioning or managing servers. Instead, they can focus solely on their application code as the cloud provider handles the infrastructure management. Therefore, while Lightsail provides a simpler, more streamlined cloud computing solution, it does not offer the serverless capabilities associated with services like AWS Lambda.
