Final answer:
Multi-tenancy in cloud computing raises concerns about security and privacy, including concerns about isolation between tenants and the proper implementation of access controls.
Step-by-step explanation:
Multi-tenancy in cloud computing refers to the practice of multiple customers or users sharing the same resources and infrastructure of a cloud service provider. While multi-tenancy offers cost efficiency and scalability, it raises concerns about security and privacy.
One major concern is the isolation between tenants. In a multi-tenant environment, there is a risk that one tenant's data or activities could be accessed or compromised by another tenant. This can be a serious issue, especially when dealing with sensitive or confidential data.
Another concern is the proper implementation of access controls. Each tenant should have their own set of permissions and access rights to ensure that they can only access their own data and not that of other tenants. Improper access controls can result in data breaches and unauthorized access.
