In a cloud environment, what does multi-tenancy refer to?

1. Sharing of physical resources among multiple users

2. Single use of applications by one organization

3. Dedicated network paths for each organization

4. Collaborative use of storage

The correct answer is: Sharing of physical resources among multiple users

Multi-tenancy in a cloud environment refers to the architecture where multiple users, or tenants, share the same physical resources while maintaining data isolation and privacy. This architecture is a key characteristic of cloud computing models, as it allows for efficient use of resources, leading to cost savings and improved scalability. In a multi-tenant environment, multiple customers can use the same infrastructure, such as servers and storage systems, effectively sharing the hardware and software resources. Each tenant has its own data space, which is securely isolated from that of other tenants, ensuring confidentiality and security. This sharing of physical resources is what allows cloud service providers to offer services at competitive prices, as they can optimize their infrastructure to support many users simultaneously. The other options focus on different concepts that do not align with the definition of multi-tenancy. For example, a single use of applications by one organization implies a dedicated environment rather than a shared one; dedicated network paths suggest isolated infrastructure rather than shared resources. Collaborative use of storage can imply multiple users accessing resources but does not necessarily involve the isolated and secure handling of data characteristic of multi-tenancy.
