Which factor is crucial when changing to cloud-based services regarding cost?

The shift to cloud-based services often involves a subscription model, which is a fundamental aspect of their cost structure. This means businesses typically pay a recurring fee to access the software rather than making a large upfront investment in one-time purchases. Subscriptions can allow for better cash flow management, as they spread costs over time, which makes budgeting easier for companies.

Many cloud services also offer a pay-as-you-go model, which can help organizations scale their expenses according to their needs. Additionally, businesses benefit from regular updates and access to the latest features without the need for significant upgrades or additional purchases, further contributing to their overall cost-effectiveness.

The other provided options do not accurately reflect the nature of cloud-based services. For instance, while ownership may be a concern, it is not as relevant to the immediate cost implications as understanding that most cloud services operate on a subscription basis.
