Cloud object storage stores data as objects. Each object usually contains the data itself, metadata, and a unique identifier. It is built for large-scale unstructured storage.
Where object storage is used
Object storage is common for backups, media files, logs, data lakes, static websites, archives, and application assets. It can scale to very large amounts of data.
Object storage versus block storage
Block storage is usually attached to a server like a disk. Object storage is accessed through APIs and is better for files and large collections of data.
Object storage is the cloud storage choice when scale, durability, and API access matter most.
