What term describes the concept of sharing resources with other cloud customers simultaneously?

The term that describes the concept of sharing resources with other cloud customers simultaneously is multitenancy. This architecture allows multiple users or tenants to share the same physical infrastructure and resources while keeping their data separate and secure. Multitenancy is a fundamental characteristic of cloud computing, as it enables efficient resource usage and cost savings for both cloud providers and customers. Each tenant operates in a logically isolated environment, ensuring that their individual applications and data remain private, even though they share the same underlying hardware and software resources. This model is crucial for SaaS (Software as a Service) applications, enabling providers to scale services rapidly while maintaining operational efficiency.

In contrast, virtualization refers to the technology that allows multiple virtual instances to run on a single physical machine, which is a component that can support multitenancy but does not directly describe the sharing of resources among multiple customers. Scalability refers to the ability to adjust resources according to demand, and segmentation typically refers to the practice of dividing networks or systems into smaller parts for management or security purposes, neither of which accurately captures the essence of sharing resources simultaneously among different customers.
