The greatest security risk in this scenario is that data may be commingled with other tenants' data on the public cloud infrastructure. Data commingling occurs when data from different sources or customers are mixed together without proper segregation or encryption. This may result in data leakage, unauthorized access, or loss of confidentiality and integrity. Data commingling is a common challenge in public cloud environments, where multiple customers share the same physical resources and network. System downtime, infrastructure management, and cloud provider certification are also potential risks in this scenario, butthey are not as great as data commingling.
