Which option is best for storing data with a flexible pay-per-use model?

  1. Cloud Drive

  2. Cloud Storage

  3. Cloud Computing

  4. None of the above

The correct answer is: Cloud Computing

The option representing the best choice for storing data with a flexible pay-per-use model is cloud storage. Cloud storage services, such as Amazon S3 (Simple Storage Service), provide scalability, flexibility, and a payment model where customers pay only for the storage and bandwidth they actually use. This allows users to store varying amounts of data without having to commit to a long-term contract or worry about underutilizing resources, which is a key benefit of cloud storage solutions. Cloud computing refers to various services that provide computing resources over the internet, which can include storage, processing power, and software applications. While it enables a pay-per-use model, it is broader and not specifically focused solely on data storage. In contrast, a cloud drive typically implies a consumer-level solution for personal storage, and it may not offer the same scalability or business-grade features as a dedicated cloud storage service. None of the other options encapsulates the specific focus on a flexible pay-per-use model for data storage as effectively as cloud storage does.
