According to the storage ladder protocol, which of the following statements is true?
You should not use cloud storage for mission critical data, but you can use it to store non-mission critical files. What is the Storage Ladder Protocol? The “Storage Ladder” concept was first introduced by David A. Patterson of UC Berkeley and Garth Gibson from Carnegie Mellon University in a 1993 paper called “A Case For Redundant Arrays Of Inexpensive Disks (RAID)”.
They described how an organization’s storage needs evolve over time: The three stages are: Diskettes – These were used in the 1980s when they cost $400 per megabyte and had no capacity greater than 50MB. Tape libraries – This became popular with organizations that needed more space than diskettes offered; Organizations moved from diskettes to tape libraries because they were cheaper than hard drives. They could store more data and, as a result, organizations had less of a need for frequent backups. Hard disks – Organizations that grew out of their capacity with tape libraries can now use external or internal storage arrays that offer better performance and reliability at the cost of higher upfront costs per megabyte (e.g., $400 vs. $0).
