What is S3-compatible storage?

In short

S3-compatible object storage lets existing tools, SDKs and migration scripts work against a provider's buckets without changes.

S3-compatible object storage means a bucket that answers the same API as Amazon's S3, so the tools, SDKs and migration scripts you already have keep working. It is the practical test for moving data between providers without rewriting anything. 4everland, AceCloud, Akamai Connected Cloud, Alibaba Cloud and Angani each offer an S3-compatible layer, so you can point an existing client somewhere else and keep the same commands.
