Instance

PronunciationIN-stans

Definition

An instance is a single, running copy of a virtual server or a software application. It represents a specific, isolated environment where your code executes.

Where you hear it

In cloud infrastructure management, server deployment, and virtualization discussions.

Examples

  • We need to spin up a new instance to handle the increased traffic.
  • The application instance crashed due to an out-of-memory error.

Common mistake

Confusing an instance with the underlying physical hardware; an instance is a virtualized slice of resources, not the entire physical machine itself.
