Understanding the storage types

Which storage technology will fit into your OpenStack cloud implementation? To answer this question, it is necessary to differentiate between different storage types, which will make sense of each use case of your further decision. The fact that OpenStack clouds can work in tandem with many other open source storage solutions might be an advantage, but on the other hand, it can be overwhelming.

Thus, you are tasked in the beginning as you have to decide what you need—persistent or ephemeral storage?

Ephemeral storage

For the sake of simplicity, we will start with the nonpersistent storage, which is called ephemeral storage. As its name suggests, a user who actively uses a virtual machine in the OpenStack environment will lose the associated disks once the VM is terminated.

Persistent storage

Persistent storage means that the storage resource is always available. Powering off the virtual machine does not affect the data. We can divide it into two persistent...
