Which one of the following is not a characteristic of cloud computing?

1. Ubiquitous

2. Fixed

3. On-demand

4. Convenient

The correct answer is: Fixed

Cloud computing is fundamentally characterized by various attributes that enable its flexibility and scalability. One of the primary characteristics is its ubiquitous nature, allowing access to services and resources from virtually anywhere with an internet connection. Additionally, cloud computing is designed to be on-demand, meaning that users can provision and use resources as needed without significant lead time. This dynamic nature enhances the user experience by providing resources when required. Another significant attribute of cloud computing is its convenience, as it facilitates easy management and administration of resources without the need for extensive physical infrastructure or hardware maintenance by the end user. In contrast, the notion of being "fixed" does not align with the core principles of cloud computing. Cloud services are inherently designed to be elastic and adaptable, allowing organizations to scale up or down based on their evolving needs. The fixed nature implies a static allocation of resources, which is contrary to the inherent flexibility and dynamic provisioning that cloud computing offers. Therefore, the characteristic that does not fit the definition of cloud computing is indeed the fixed aspect.
