Explanation

In cloud environments, customers typically do not have physical access to the underlying storage media, making traditional disposal methods like physical destruction or degaussing impractical. Cryptoshredding (also called crypto-erasure) solves this by destroying the encryption keys used to protect the data, rendering the encrypted data permanently unreadable. Overwriting may not be feasible on cloud storage due to distributed and virtualized architectures. Cold fusion and melting are physical destruction methods inapplicable in cloud contexts.
