A business distributes its IT workload across multiple cloud providers to prevent reliance on a single vendor. Which type of deployment model is this?

An on-premises deployment model involves hosting IT infrastructure and services within the physical confines of the organization’s facilities. This model does not utilize external cloud providers, thus contradicting the premise of distributing workloads across multiple vendors.

The hybrid cloud model combines on-premises resources with cloud services, allowing for a mix of public and private cloud solutions. However, it does not inherently imply the use of multiple cloud providers. Instead, it primarily focuses on integrating both local and cloud-based resources, which does not meet the criteria of the question.

A public cloud deployment involves services offered by third-party providers over the internet, accessible to multiple organizations. While it represents a cloud-based solution, it does not address the aspect of utilizing multiple vendors, which is central to the multicloud model.
