Object storage is a flexible and highly available cloud storage solution designed for storing and accessing large amounts of unstructured data such as images, videos, and logs. Unlike traditional storage systems, object storage does not rely on a complex directory hierarchy. Instead, it uses a flat structure and can scale on demand. It also supports remote access via HTTP/HTTPS APIs, making it widely used for website static asset hosting, mobile app backends, backups, archival storage, and AI data lakes.
Today, we focus on cloud providers that offer free object storage plans, comparing their resource quotas, eligibility requirements, and practical use cases to help you identify the most cost-effective free storage solution.

Frequently Asked Questions (FAQ)
Q1: What is the difference between object storage and traditional file storage or cloud drives?
Object storage uses a key-value architecture without hierarchical directories. It is accessed via APIs and is better suited for automated systems and programmatic access, whereas traditional cloud drives are designed for manual user operations.
