A federated ai registry links model catalogs across separate cloud accounts or teams. You set it up by sharing metadata indexes while keeping model weights local. Most engineering teams start with a single central model bucket for all apps. That setup breaks down when separate units own their own cloud accounts. Teams often respond by granting broad cross-account roles to shared storage buckets. Overly broad roles expose private training data and allow untracked model changes.
How a federated ai registry works in practice
In a federated ai registry, each team runs its own local model store. A central catalog service reads model metadata from each local store. The metadata includes model names, version tags, owner teams, and evaluation scores. The large model files and training sets stay inside the local cloud account. Teams use cross-account identity roles to link each local store to the catalog. Each local store grants a read-only metadata role to the central index. Build pipelines push new model versions to the local store first. The local store then sends an event to update the central index. Developers search the central catalog to find approved models across the whole company. When a developer picks a model, they request a role for that store. Identity providers check group membership before granting a token for that model store.
What native federation solves and what keeps the session active
This native architecture solves model discovery across separate cloud accounts and regions. Teams do not need to copy massive weight files into one central bucket. Local data owners keep control over their own storage buckets and KMS keys. Cross-account identity roles also stop random users from deleting production model files. Still, registry federation only controls who can pull a model artifact at deploy time. It does not check what a running model or agent does in flight. Once an app loads a model or gets a database role, the registry steps back. The registry cannot see if an agent runs a destructive database query. It also cannot rewrite sensitive fields like emails or phone numbers in query results. A shared service role still gives the running app full access to downstream data. Teams need runtime checks on every query and command, not just artifact storage rules.
Managing permissions across local model stores
To keep local stores safe, split human roles from automated pipeline roles. Build pipelines need write permissions to push new model versions and metadata tags. Human engineers only need read permissions to view metadata and test evaluation metrics. Production apps should only pull model versions that carry an approved stage tag. You can enforce this rule using tag-based conditions on your cloud storage roles. Never share a single static storage key across multiple teams or model runners. Instead, map each workload identity to the specific model path it requires. Review cross-account role trust policies every quarter to remove old project accounts. Log every model download event in your central security log for audit checks. Pair these storage rules with runtime data masking for card numbers and national IDs.

Add runtime guardrails and masking beside your databases and APIs
Login rules, role grants, and CI checks govern who connects to your stack. Yet any allowed script, engineer, or AI agent still runs commands with the full scope of its role. For workloads on Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes, SSH, or internal HTTP services, hoop.dev sits beside the service as an open-source proxy, a sidecar for your database or API.
Before a query runs, hoop.dev guardrails check the statement against your rules. An AI Analyzer you configure can score intent or hold risky calls for human review. Next, hoop.dev data masking rewrites sensitive fields in responses, and each verdict is logged per listener. Explore the MIT-licensed project on GitHub.
Frequently asked questions
How does a federated registry differ from a central model registry?
A central registry stores all model files and metadata in one shared account. A federated setup keeps model files in local accounts and only shares metadata.
Do teams need to copy model weights across cloud regions?
No, model weights stay in the local storage bucket where the team trained them. Workloads pull the files directly from the local store after checking the catalog.
Does a model registry filter sensitive data during model inference?
No, a model registry only tracks version files and storage permissions before deployment. It does not inspect live database queries or mask emails and card numbers.
