Question

In OpenStack, ephemeral storage is managed by
a. Swift
b. Keystone
c. Nova
d. Cinder

Answer 1

Answer:

c. NOVA

Explanation:

In OpenStack, ephemeral storage is managed by NOVA.

The disks associated with VMs are ephemeral  by NOVA, meaning that from the user’s point of view they disappear when a virtual machine is terminated.

Other option of storage is Persistent storage. There are three types of persistent storage: Object Storage, Block Storage, and File-based storage.

Answer 2

In OpenStack, ephemeral storage is managed by Nova out of Swift, Keystone, Nova and Cinder.

It is a core project of OpenStack that implements libraries associated with services to self-serviced access to computing resources on a huge scale when requested.

When Nova is used, the user does not have access to persistent storage. The disks in Virtual machines are ephemeral or temporary.
