Block Storage
Block storage is one of the infrastructure platform storage primitives exposed to the upper layer and usually dynamically managed through APIs.
Block Device
A block device is a storage device that moves data in sequences of bytes or bits (blocks). These devices provide random access to fixes-size blocks of data and generally use buffered I/O. Examples include hard disks, CD-ROM drives, and flash drives. A block device can be physically attached to a computer or accessed remotely as if it were physically attached to the computer.
Examples: Amazon Elastic Block Store (ESB) volumes.
Object Storage
Object storage blobs: immutable, unstructured data such as images, videos and documents.
Examples: Amazon S3 service, Google Cloud Storage service, Azure Blob Storage.
