Cloud Storage Concepts

Storage is a core part of cloud computing. It is used to store data such as files, images, databases, and application data. In cloud, storage is mainly divided into three types

• Object Storage
• Block Storage
• File Storage

Each type is used for different purposes.

1. Object Storage

Object storage stores data as objects instead of traditional files or blocks.

Each object contains

• Data
• Metadata information about the data
• A unique identifier

Examples:

• Amazon Web Services S3
• Google Cloud Cloud Storage

Example:

• If you upload images for your wallpaper website, they are usually stored in object storage.

Why use object storage

• Highly scalable
• Can store huge amounts of data
• Best for unstructured data like images, videos, backups

You access data using a URL or API, not like a normal file system

2. Block Storage

Block storage divides data into small blocks and stores them separately. These blocks are combined to act like a disk attached to a server.

Examples:

• Amazon Web Services EBS
• Microsoft Azure Managed Disks

Example:

• If you run a database or install an operating system on a cloud server, it uses block storage.

Why use block storage

• High performance
• Low latency
• Best for databases and operating systems

It behaves like a hard drive attached to your server

3. File Storage

File storage stores data in a hierarchical structure like folders and files. It works similar to your computer file system.

Examples:

• Amazon Web Services EFS
• Google Cloud Filestore

Example:

• If multiple servers need to access the same files like shared documents, file storage is used.

Why use file storage

• Easy to use
• Shared access across multiple systems
• Familiar file system structure

Data is organized in directories and accessed using file paths

4. Object vs Block vs File Storage

Object Storage

• Stores data as objects
• Best for images, videos, backups
• Highly scalable

Block Storage

• Stores data in blocks
• Best for databases and OS
• High performance

File Storage

• Stores data in files and folders
• Best for shared access
• Easy to manage

• Object storage is used for large scale unstructured data
• Block storage is used for high performance applications like databases
• File storage is used for shared file systems
• Understanding these storage types helps you choose the right storage solution based on performance, scalability, and use case.
