👉 A paying fluid, often seen in the context of cloud computing and software-as-a-service (SaaS) models, refers to a pricing structure where the cloud service provider charges based on the actual usage of resources consumed by the customer. This means that instead of paying a fixed monthly fee, the customer only pays for what they use—such as storage space, processing power, or data transfer. This model offers flexibility and cost efficiency, as customers only incur expenses proportional to their needs, making it particularly appealing for businesses with variable or unpredictable workloads.
