Object storage is a data storage architecture for handling large amounts of unstructured data. Unlike traditional file systems that organize data in a file hierarchy, object storage systems manage data as distinct units, or objects. Each object includes the data itself, a variable amount of metadata, and a globally unique identifier. This structure is highly scalable and is used by many cloud-native applications.

Cloud object storage was developed to handle modern data management requirements. It offers an affordable storage solution with industry-standard data integrity, durability, and availability. Businesses use object storage for everything from data backup and disaster recovery to data analytics and machine learning. A key benefit of this data storage model is having the ability to use non-specialist hardware, which helps reduce the total storage costs for the customer.

However, choosing the right provider is important because each provider is different. The file sizes you can save vary dramatically (from 50 GB files to 5TB files). Also, factors like the provider’s pricing model, egress fees, performance, and integration with other services should be considered.
