Correct answer & explanation
✓
On-demand self-service
On-demand self-service enables users to provision resources automatically as needed, without requiring human interaction with the provider.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Measured service
Why it's wrong here
Measured service is a cloud characteristic that meters usage and provides transparency for both provider and consumer, typically enabling pay-per-use billing. However, it is not the key characteristic in this context because it focuses on cost attribution and resource monitoring rather than the consumer's ability to independently obtain and configure resources. While important, measured service supports the commercial model of cloud but does not define the user experience of immediate provisioning.
- ✗
Resource pooling
Why it's wrong here
Resource pooling allows a cloud provider to serve multiple consumers using a shared, multi-tenant infrastructure, dynamically assigning virtual and physical resources according to demand. This characteristic is more about the provider's operational efficiency and cost reduction than about the consumer's capability to request resources without delay. As such, resource pooling is a foundational aspect of cloud economics but not the central feature that the question highlights.
- ✓
On-demand self-service
Why this is correct
On-demand self-service is the essential characteristic where a consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service provider. This capability is the key differentiator because it directly enables the agility, elasticity, and perception of unlimited resources that organizations expect from cloud computing. It shifts control to the consumer, making it the defining trait in NIST's cloud model.
- ✗
Broad network access
Why it's wrong here
Broad network access describes the availability of cloud resources over the network through standard mechanisms and protocols, allowing access from heterogeneous client platforms like laptops, mobile phones, and workstations. While this is a necessary condition for cloud utility computing, it is not the key characteristic because it addresses reachability rather than the consumer's autonomy to provision and manage services. The question specifically targets the self-service nature of cloud, not just the communication pathway.
