multiguest

Multiguest is a term used to describe a design approach or system architecture intended to support multiple independent guest entities within a single shared environment. The term does not refer to a single standard specification and its exact meaning varies across domains. In general, multiguest emphasizes isolation, coordination, and scalable accommodation of multiple guests or tenants.

In computing, multiguest commonly appears in virtualization, containerization, and multi-tenant software. It describes environments that host several isolated guest environments—such as virtual machines, containers, or sandboxed services—on a common host. The goal is to enable concurrent operation, controlled resource allocation, and secure boundaries between guests. Techniques include virtualization with hypervisors, orchestration of containers, and resource schedulers that enforce quotas and prioritization. Key concerns include security isolation, performance interference, and management complexity as the number of guests grows.

In hospitality and service platforms, multiguest may describe arrangements that accommodate multiple guests under a single booking or account, or software features that manage shared accommodations, group reservations, or co-lodging. In software as a service, it can refer to multi-tenant architectures where separate guest accounts share a common data model while remaining isolated.

Usage of the term is informal and context-dependent; there is no widely adopted standard definition. When encountered, it generally signals a focus on supporting several independent guest entities and their interactions within one system.
