AWS Technical Essentials Practice

A "Serverless" architecture is characterized by its ability to enable developers to build and run applications without the complexity of managing server infrastructure. This means that the provisioning, scaling, and maintenance of servers is handled by the cloud service provider, allowing developers to focus more on writing code and delivering functionality rather than worrying about the underlying hardware or infrastructure management. In a serverless model, resources are automatically scaled to meet demand, and users typically pay only for the compute time consumed.

The other options reflect different aspects of traditional computing models. For instance, requiring developers to manage server infrastructure is contrary to the essence of serverless architecture, which aims to eliminate that burden. Additionally, the notion that all server resources are located on-premises does not align with serverless paradigms, where resources are typically hosted in the cloud. Lastly, the concept of storing applications in a centralized server does not capture the dynamic and distributed nature of serverless computing, which can leverage multiple microservices and functions that operate independently and are event-driven.
