What describes shared resources in cloud services?

Shared resources in cloud services refer to the concept where multiple customers utilize the same underlying physical infrastructure, such as servers, storage, and networking equipment. This model is integral to how cloud providers operate, allowing them to optimize resource usage, reduce costs, and improve scalability. By pooling resources, cloud services can provide flexible usage options, enabling customers to pay only for what they use, while benefiting from economies of scale.

This shared model allows various clients to run their applications on the same hardware, which can significantly enhance efficiency and reduce the overhead associated with maintaining individual servers for each customer. Virtualization technology plays a critical role here, allowing multiple environments to run on a single physical server.

In contrast, the other options focus on isolation or individual allocation of resources, which do not align with the concept of shared resources. Resources reserved for single customers represent dedicated infrastructure, while resources dedicated to high-security applications suggest a heightened level of isolation or security not characteristic of shared environments. Lastly, individual server storage allocated for specific users implies a physical segregation of resources, which deviates from the shared approach fundamental to cloud computing.
