Answer Description

The security team is referencing Resource Pooling. Cloud vendors use resource pooling to maximize efficiency and minimize the cost of their infrastructure. Instead of buying lots of small servers and giving customers access, they create pools of infrastructure using large servers. Using virtualization the large servers are divided up into smaller chunks and assigned to customers based on their computing requirements. This means it is likely that in a public cloud you have your own virtual resources, but those virtual resources are sharing the same physical resources as other customers of the cloud vendor.
