# Hosting and storage

## Hosting environment

Imengine runs using a Docker image and the service is connected to one *Open Content*.

## Storage

When using Open Content, images are stored by uuid. Imengine also stores the processed image on it's own. For that it uses Amazon S3 as standard.

### Filename hash (by uuid)

All unique API requests will generate a file in the storage. For filename a **hash** is used in combination with crop details. 

### Using external images (imgsrc)

In the case of an external image we use a decoded version of the url instead.
