Which service does AWS provide?

AWS, or Amazon Web Services, is a comprehensive cloud computing platform that offers a wide array of services beyond just web hosting. The correct answer highlights the secure cloud service aspect, emphasizing that AWS provides various functions, including but not limited to computing power, storage options, databases, machine learning, and networking. This versatility allows businesses and developers to build and manage applications effectively without the need for physical server infrastructure.

In contrast, the other options are limited in scope. While AWS does offer secure web hosting services, it encompasses much more than just that single service, making the first option too narrow. The third option mentions free public file storage, which could refer to other services but doesn't encapsulate the full range of AWS offerings. Finally, a personal computing solution is not a primary feature of AWS, as it primarily focuses on cloud-based infrastructure and services rather than individual computing devices.

Thus, identifying AWS as a secure cloud service with various functions accurately describes its role and capabilities in the tech landscape.
