Storage Provisioning

A method performed by an encryption node for provisioning storage in a system, wherein the encryption node is associated with an application node and the application node is configured to run at least part of one or more applications, the method comprising:

• in response to an unencrypted storage volume becoming available to the encryption node from a storage provisioning node of the system, generating an encrypted storage volume from the unencrypted storage volume and initiating provisioning of the encrypted storage volume to make the encrypted storage volume available at a compute node of the system for use by the application node.

An encryption node comprising:

• processing circuitry configured to, in response to an unencrypted storage volume becoming available to the encryption node from a storage provisioning node of a system, generating an encrypted storage volume from the unencrypted storage volume and initiating provisioning of the encrypted storage volume to make the encrypted storage volume available at a compute node of the system for use by an application node with which the encryption node is associated, wherein the application node is configured to run at least part of one or more applications.

A storage provisioning node of a system for provisioning storage in the system, the storage provisioning node comprising:

• processing circuitry configured to, in response to a first request for an unencrypted storage volume, initiate provisioning of the unencrypted storage volume to make the unencrypted storage volume available at a compute node of the system to an encryption node for the encryption node to use in the generation of an encrypted storage volume to be made available at the compute node for use by an application node, wherein the application node is configured to run at least part of one or more applications and the encryption node is associated with the application node.
