Storage

Overview

Simple Object Storage (SOS) is an S3-compatible object storage to store your assets, files, and metadata. Furthermore, it is a cost-effective solution to support your application and backup or serve your data from any Exoscale zone with no hidden fees, using your existing S3-compatible tooling and a familiar API.

• Simple to use
• High-available, replicated 3 copies of each object
• URLs to files can be configured with ACLs
• ACLs (Access Control List) permission control:
  • private - only with API key accessible
  • public-read - everyone can read, e.g. for static files
  • public-read-write - everyone can read and write -> NOT RECOMMENDED
  • manual edit - grant specific permissions to other orgs
