# Compute Image

A Compute Image is a type of storage where the internal data is immutable. It is primarily used as a source for launching Compute Instances and for backup purposes.

To draw a comparison with a PC, a Compute Image is like a write-once CD-R; its data cannot be modified. It is commonly used to store an operating system for booting a new PC or to archive files that will not be changed in the future. The main difference is that a physical CD-R has a fixed storage limit, whereas Compute Images on the cloud do not have a size limit for the data you can store.

Furthermore, the data within a Compute Image is replicated across all Availability Zones. This prevents data loss and ensures that the image can be accessed and used quickly from any Availability Zone.
