Frequently asked questions
Quick answers.
What is object storage?
Object storage keeps data as objects, each with its data, metadata and an identifier, in a flat namespace accessed over HTTP APIs such as S3. It scales to billions of objects and suits unstructured data.
What does S3-compatible mean?
The service supports the same API as Amazon S3, so applications and tools written for S3 can use it with little change. Check support for features such as versioning and object lock.
Object, file or block storage?
Object storage suits large unstructured data and backups. File storage suits shared files and directories. Block storage suits databases and virtual machines that need low-latency volumes.
What affects object storage cost?
Capacity, storage class, request counts and especially egress charges for data leaving the provider. Some services waive or reduce egress fees.
Can object storage run on premises?
Yes. Software such as MinIO, Ceph and Cloudian, and appliances from several vendors, provide S3-compatible object storage in your own data centre.
