Disk zeroing in the cloud
Netapp disk initialize
As far as I’m aware, “disk sanitization” is a licensed function that is used to permanently erase data from a disk or collection of disks. Why can’t we do this with “zero disk,” which isn’t a licensed feature?
@Eswar, how are you today?
Disk sanitization is a much more systematic method of deleting data on the disk(s) by repeatedly overwriting the blocks with random data or a particular pattern to obliterate any possibility of data recovery.
Disk zeroing is the process of writing zeros to the disk twice.
The latter isn’t regarded as stable since it could potentially still be retrieved.
Despite the fact that there is still some controversy about this, the US government continues to believe that multiple overwrites are a positive thing for securely erasing the disk.
I hope this information is useful.

Thick vs thin disk provisioning
Can anyone recommend a cloud service that requires no prior knowledge and does not have a file size limit? To be frank, the lack of a file size cap is more significant to me than the lack of expertise, since I’ll be encrypting my files before uploading (although zero knowledge would be very nice). I don’t want to use something from a failing business that could go bankrupt at any time, so a semi-popular service is much safer. Sync.com caught my eye; it’s located in Canada and costs $8 a month for 2 TB of data.

Expand a thin provisioned virtual disk
Some multi-tenant public cloud providers have “dirty disks” that are not completely wiped clean after each usage by a customer, leaving potentially confidential data accessible to other users, according to a forensic IT study conducted by a UK security consultancy.

Context Information Security officials conducted a review last year to see whether they could access data from other customers inside four public cloud environments. “We were pleasantly shocked,” says Michael Jordan, Context’s research and development manager. “We were able to access data that had been there for a long time using a very simple test.” Do you know where your cloud data is?

Thick versus thin disk provisioning basics in vmware
I tried a lot of different combinations and was only able to boot from openstack blockstorage volume v3 with my image’s image id package. However, after installation, this configuration forces me to boot from this volume and does not allow me to boot from the target volume.
I also tried setting boot index=0 on a blank block device and boot index=1 on a volume generated from an iso image, so that the vm would verify that the first device isn’t bootable and run the machine from the second volume (as in a standard PC), but this failed with an error saying “No bootable device.”
