What is object storage?

Object storage is a type of storage where data is broken into smaller pieces called objects. Each object has an identifier. They are stored in a single repository called a container or a bucket. These objects can then be distributed across multiple nodes or servers.

Object storage is a relatively new model compared to traditional file storage or block storage. It's often called the storage of the cloud since it eliminates the scaling limits of traditional file systems. Unlike files in file storage, objects are stored in a flat structure. They don't follow any directory, folder, etc.

Besides a unique identifier, each object contains data, metadata, and attributes related to the metadata.
