What identity Atlan presents to your AWS account, which values are tenant-specific, and exactly what to request from support in a single ticket. For how tenant-specific values work across all connectors and clouds, see [Atlan Network Details](https://docs.atlan.com/llms/governance/administration/atlan-network-details/llms.txt).

## Why there is no IP allowlist page for Glue

Atlan's Glue traffic goes to AWS's public Glue API endpoints (`glue.<region>.amazonaws.com`) over TLS. Access control happens entirely through AWS IAM - your side never receives an inbound connection, so there is nothing to open in a firewall and no Atlan IPs to allowlist for this connector.

If your organization restricts *which identities* may call your AWS account (service control policies, IAM boundaries), the values below are what your security team asks about.

## Which value applies to me?

| Your setup | The Atlan-side identity involved | Where to get it |
|---|---|---|
| IAM access keys | None - the IAM user lives in *your* account; Atlan only stores its keys (encrypted) | Nothing needed from Atlan |
| Cross-account IAM role | **Node instance role ARN** - Atlan's per-tenant AWS identity that assumes your role | Support ticket ([role guide, Phase 1](https://docs.atlan.com/llms/connectors/aws-glue/connect-with-a-cross-account-iam-role/llms.txt)) |
| Self-deployed agent | Agent runs with credentials you manage in your own network | [Self-deployed runtime docs](https://docs.atlan.com/llms/platform/self-deployed-runtime/llms.txt) |

## Node instance role - tenant-specific, via support

> **Info: Tenant-specific value - raise a support ticket**
>
>
> Each Atlan tenant has its **own** node instance role. A common mistake in multi-environment setups is reusing the dev tenant's ARN in the prod trust policy - the ARNs differ per tenant even for the same organization.
>
> [Raise one support request](https://docs.atlan.com/llms/platform/submit-request/submit-request/llms.txt) from within Atlan stating:
>
> - Your **tenant URL** for every environment you're connecting (for example, `example-corp-dev.atlan.com`, `example-corp.atlan.com`)
> - That you're setting up **AWS Glue with role delegation** and need the **node instance role ARN per tenant**
> - (If already known) the **role name and 12-digit AWS account ID** you'll create for each environment - support can then complete the Atlan-side allowlisting in the same ticket instead of a second round-trip
>

The ARN support returns looks like this (illustrative):

```
arn:aws:iam::444455556666:role/example-tenant-nodeinstance-role
```

## Where Atlan's Glue traffic goes

| Destination | Purpose | Direction |
|---|---|---|
| `sts.amazonaws.com` / regional STS endpoints | Assuming your cross-account role (role method only) | Atlan → AWS |
| `glue.<region>.amazonaws.com` | Read-only Glue Data Catalog API calls (`GetDatabases`, `GetTables`, …) | Atlan → AWS |

All traffic is TLS-encrypted and initiated by Atlan. Nothing connects inbound to your network, and no table *data* is read - only catalog metadata.

## When values change

- The node instance role ARN is stable for the life of your tenant. It can change during a major infrastructure migration - Atlan announces this to tenant admins in advance, and your trust policies need updating.
- If you rename or recreate *your* IAM role, the Atlan-side allowlist must be updated too - the allowlist names your exact role ARN. Raise a ticket with the new ARN (this also applies when adding roles for new AWS accounts).
