The risk that a cloud provider might go out of business and the cloud customer might not be able to recover data is known as:

The correct answer is vendor closure. This term refers to the risk associated with a cloud service provider (CSP) going out of business, which can leave customers without access to their data. In the cloud computing environment, customers typically store their data with a third-party provider, meaning that if the provider ceases operations or faces financial difficulties, the customer may struggle to retrieve their data.

Understanding this risk is crucial for organizations that depend on cloud services for data storage and management. Data governance strategies typically include contingency planning for such events, including considering service level agreements and conducting due diligence on a provider's financial health.

Vendor lock-out and vendor lock-in refer to phenomena related to the difficulty of migrating away from a particular provider due to proprietary technologies or contractual obligations. These concepts relate to the challenges of maintaining flexibility and competitiveness in choosing service providers but do not specifically address the risk of the provider going out of business. Vending route is not a recognized term in the context of cloud security and therefore would not apply to this scenario.
