Azure Files

Azure Files is a fully managed cloud file share service from Microsoft Azure that provides hosted SMB and NFS file shares accessible from cloud and on-premises clients using standard file system protocols and the FileREST HTTPS API. It supports identity-based authentication via Active Directory and Microsoft Entra ID, snapshots, soft delete, and Azure File Sync for hybrid scenarios. The FileREST data-plane API uses shared key, shared access signatures (SAS), or Microsoft Entra ID OAuth 2.0 bearer tokens for authentication, while the control plane uses Azure Resource Manager.

Azure Files publishes 7 APIs on the APIs.io network, including Account API, Directories API, and 5 more. Tagged areas include Storage, File Storage, File Shares, NFS, and Cloud.

Azure Files’ developer surface includes developer portal, support, authentication, documentation, pricing, signup flow, engineering blog, and 8 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/azure-file-storage: open an issue to ask a question, or submit a pull request to add artifacts.
