Which of the following is a key feature of HPE GreenLake?

The pay-per-use model is a key feature of HPE GreenLake, as it aligns with the consumption-based IT philosophy that many organizations are increasingly adopting. This model allows businesses to only pay for the resources they actually use rather than investing heavily in upfront capital expenditures. Such flexibility enables organizations to scale their IT resources according to their needs and adjust costs accordingly, providing financial predictability and efficiency. This approach supports a cloud-like experience for users while still allowing on-premises infrastructure, making it particularly appealing to businesses looking to control costs and optimize their IT budgets.

In contrast to this model, perpetual licensing typically involves a one-time upfront payment for software, which does not offer the same level of flexibility as a consumption-based model. On-premise only solutions suggest limited deployment options, which is not reflective of GreenLake's hybrid nature. Furthermore, while open-source compatibility may be an attractive feature in some contexts, it is not a defining characteristic of HPE GreenLake specifically, which focuses on providing a managed service experience that combines cloud services with on-premises resources.
