Question
What is the definition of object-based storage?
A. Object storage is a method of storing files in individual blocks located on a hard drive.
B. Object storage is a method of storing files based on attributes and metadata.
C. Object storage is a method of storing files based on folders and subfolders.
D. Object storage is a method of storing data based on a hierarchical structure of directories and subdirectories.
Answer
B. Object storage is a method of storing files based on attributes and metadata.
Explanation
In object storage, files are stored as objects based on attributes and metadata. Each object consists of data, metadata, and an object key. The metadata has information about the data (object size, object purpose, and more), and the object key is the unique identifier of the object.
Object-based storage, also known as object storage, is a method of storing data as discrete units called objects. Each object contains the data itself, a variable amount of metadata, and a globally unique identifier. The metadata includes information about the object’s content, such as its creation date, owner, access control policies, and custom attributes defined by the user or application.
In object storage, data is not stored using a hierarchical structure of directories and subdirectories like in traditional file systems. Instead, objects are stored in a flat address space and organized based on their metadata attributes. Applications access objects through API calls using the object’s unique identifier rather than its file path.
This approach provides several advantages over traditional file systems:
- Scalability – Object storage can scale to massive amounts of data and objects without degrading performance.
- Flexibility – Rich metadata allows for more sophisticated data management, search, and analytics capabilities.
- Simplicity – Applications can store and retrieve data objects without needing to know their physical location or navigate complex directory structures.
- Durability – Object storage systems typically provide high levels of data durability through replication and erasure coding.
So in summary, object storage is a method of storing data based on attributes and metadata (B), not as individual blocks on a hard drive (A), using folders and subfolders (C), or in a hierarchical directory structure (D). It enables more scalable and flexible data storage and management compared to traditional file systems.
