What type of file storage in cloud architecture often allows data to be transient and short-lived?

  1. Durable

  2. Nondurable

  3. RAID

  4. Ephemeral

The correct answer is: Ephemeral

In cloud architecture, ephemeral storage refers to a type of file storage designed for data that is transient and short-lived. This means that the data stored in ephemeral storage is often temporary and can be deleted when a virtual machine or instance is stopped or terminated. Ephemeral storage is typically used for tasks that require fast read and write access, such as temporary processing of data, caching, or session storage. This type of storage is well-suited for environments where the data does not need to persist beyond the lifecycle of the instance itself. Users leveraging ephemeral storage will find it ideal for applications where frequent data changes occur, as there's no need to retain the data after its immediate use. In contrast, durable and nondurable storage options focus on the longevity and resilience of the data stored, while RAID is a technology used for redundancy and performance improvement but does not specifically relate to the transient nature of the data.
