An instance is created from a template and can be independently configured and managed. In cloud computing, instances allow users to run applications and services on-demand without the need for physical hardware. Each instance operates in isolation, meaning that the performance or behavior of one instance does not affect others. Instances can vary in size and configuration based on the resources allocated, such as CPU, memory, and storage.
Instance Example
For example, when a user launches a new virtual server on a cloud platform like Amazon Web Services (AWS), they create an instance of a virtual machine that can run applications just like a physical server.
