Data leakage in cloud environments is a significant concern primarily due to multi-tenancy. In a multi-tenant architecture, multiple customers share the same physical infrastructure or resources without their data being isolated from each other. This shared environment increases the risk of unauthorized access, where one tenant could potentially access the data of another tenant, whether intentionally or due to a misconfiguration or vulnerability.

The nature of multi-tenancy means that security controls must be exceptionally strong to prevent data leakage. If not properly managed, gaps in security could be exploited, leading to data breaches that can result in sensitive information being exposed. The complexity of ensuring complete separation and robust security measures for each tenant contributes to this concern.

This is contrasted with single-tenancy, where each customer has their dedicated environment, substantially reducing the risk of data leakage as their data is not intermixed with that of other customers. Hybrid storage, while it has its own challenges, primarily deals with the integration of different storage types rather than the risk of leakage between users. Data redundancy involves storing duplicate data for reliability and availability, which does not inherently relate to the risk of leakage between tenants in a multi-tenant system.
