In which scenario would a "public cloud" most likely be appropriate?

A public cloud is designed to provide scalable resources that can be accessed and used by anyone, making it most suitable for scenarios where organizations require flexibility and economic efficiency. The pay-as-you-go model allows businesses to pay only for the resources they use, which is ideal for organizations with fluctuating workloads or those that need to quickly scale their resources up or down based on demand. This flexibility supports innovation and enables companies to respond quickly to changing market conditions.

In contrast, scenarios that prioritize security and compliance, such as those dealing with sensitive data or where resources are limited to one organization, are better suited to private or hybrid cloud models that offer more control and protection over the infrastructure and data.
