Which of the following is an example of Amazon Lightsail?

Amazon Lightsail is best categorized as Infrastructure as a Service (IaaS). It provides developers with a simple and low-cost way to launch and manage virtual private servers, making it easier to deploy applications and services in the cloud. Lightsail bundles essential features like virtual machines, managed databases, and storage, enabling users to set up and maintain infrastructure without the complexity often associated with more extensive cloud offerings.

In contrast, the other options describe different service models that do not align with the primary focus of Amazon Lightsail. Platform as a Service (PaaS) would typically involve a managed platform for developing and deploying applications, which goes beyond the basic infrastructure services that Lightsail provides. Similarly, Software as a Service (SaaS) refers to fully functional and managed applications available over the internet, rather than the infrastructure components. Function as a Service (FaaS), also known as serverless computing, allows users to run code in response to events without managing servers directly, which again is not what Lightsail offers.
