Costs will become predominantly fixed as the cloud provider requires a constant fee for the maintained infrastructure, independent of the enterprise's sales cycle or application usage.

Fixed costs will increase due to the necessity of higher upfront investment in cloud services, while variable costs will remain marginal depending on the data transfer rates.

While quarterly costs will become more predictable, they will be composed of both fixed subscription fees for cloud services and variable costs from unforeseen spikes in application use.

The quarterly costs would oscillate in direct proportion to the enterprise's application usage, exhibiting a variable cost structure aligned with their cyclical business trends.
