What is the term used to describe the simultaneous sharing of resources with other cloud customers?

The term that describes the simultaneous sharing of resources among multiple cloud customers is multitenancy. In a multitenant architecture, a single instance of a software application serves multiple customers, or tenants. Each tenant's data and configurations are kept secure and separate while utilizing the same shared infrastructure, such as servers, storage, and databases. This approach enhances resource utilization and efficiency while reducing costs, as it allows providers to optimize their resources and scale services dynamically.

Multitenancy is a fundamental characteristic of many cloud services, particularly in Software as a Service (SaaS) offerings, as it enables providers to serve a larger customer base with fewer resources. This contrasts with single tenancy, where each customer has their own dedicated instance, leading to higher costs and fewer efficiencies.

Resource pooling refers to the cloud provider's capabilities to manage and allocate resources dynamically as needed but does not specifically focus on the sharing aspect that multitenancy emphasizes. Virtualization is a technology that allows multiple virtual instances to run on a single physical machine but is not synonymous with multitenancy.
