State-of-the-art storage solutions

There are different types of storage in OpenStack: Ephemeral storage, Volume Storage and Object Storage. It’s important you understand the difference so you can best determine which type to use. This guide explains the differences between the two. It also describes two varieties of persistent storage you can use.

Ephemeral Storage

This type of storage is associated with a single unique instance (virtual machine). It exists only as long as the instance itself. It’s primarily used for the root filesystem and operating system of the instance. The size of ephemeral storage is determined by the flavor of the instance and the image used. Ephemeral storage persists as long as the instance isn’t deleted; it will not be lost and reset due to reboots.

If you take a snapshot of an instance based on ephemeral storage, this snapshot is saved as an image, in the image storage. The size of the created image will be the same as the used storage at the time of taking the snapshot.

Volume Storage (Block Storage)

Volume storage (also known as block storage) is manually created by the user. Upon creation, Its size can be determined by the user. You can use a volume as an external hard drive and it's to attach it to an instance. Please note that it can only be attached to a single instance at a time, although you can detach and reattach it to different instances.

Because every application and every platform is unique, we offer three different tiers so you can choose a storage solution that suits your needs. Our Low tier is the best solution for large amounts of data that do not require high I/O performance, such as backups. Our Regular tier uses HDD storage and can be used for most applications that do not require the highest performance possible. In case you are looking for the best, and fastest storage solution on the market, please select our High tier. It's extremely fast because of state-of-the-art SSD technology.

If you take a snapshot of a volume or an instance based on a bootable volume, this snapshot is stored on the same storage you use for the volume. The size of the snapshot is equal to the size of the allocated space of the volume you make a snapshot of.

Object Storage

With object storage, users can easily access files via an API or URL. It consists of clustered enterprise storage hardware and is designed to easily scale when using large amounts of data. Object storage is an inexpensive solution for storing, for example, images of instances, snapshots, photos, videos and backups.

Fuga Cloud allows you to create or upload images yourself. You can use an image as a template for your instance. You also have the option to use an image to create a bootable volume (which you can mount to an Instance).


A snapshot can be seen as an exact recording of a volume or Instance at a specific time, including all its data. Snapshots can be used to launch a new instance. Both images and snapshots use our highly available cluster and are stored completely redundantly (N+2).
