How many categories of storage devices broadly exist in cloud?

There are three main categories of storage devices broadly exist in cloud: object storage, block storage, and file storage.

• Object storage is a type of cloud storage that stores data as objects. Objects are self-contained units of data that can be any size, and they are accessed using a unique identifier. Object storage is often used for storing unstructured data, such as images, videos, and documents.
• Block storage is a type of cloud storage that stores data as blocks. Blocks are fixed-size units of data, and they are accessed using a block device name. Block storage is often used for storing structured data, such as databases and virtual machines.
• File storage is a type of cloud storage that stores data as files. Files are named units of data, and they are accessed using a file system. File storage is often used for storing data that needs to be accessed by multiple users, such as shared documents and applications.

The best type of storage for a particular application depends on the type of data being stored, the access patterns, and the performance requirements.
