Atlan connects to Informatica Cloud Data Integration (CDI) through a secure REST API-based architecture that enables metadata discovery, lineage extraction, and asset cataloging.
Network connectivity
Atlan establishes secure connections to Informatica CDI through HTTPS protocols and standard web ports.
Connection architecture
Connection requirements
- Protocol: HTTPS (TLS 1.2 or higher)
- Port: 443 (standard HTTPS port)
- Domain format: Example
dmp-{region}.informaticacloud.com - Network access: HTTPS connections from Atlan infrastructure to Informatica Cloud
Firewall configuration
- Inbound rules: Enable HTTPS traffic from Atlan tenant
{orgname}.atlan.comto Informatica Cloud domain
Authentication and authorization
Atlan uses Informatica's native authentication system with role-based access control for secure data access.
Authentication method
- Type: Native authentication (username/password)
- Protocol: HTTPS-based credential exchange
- Session management: Token-based session handling
- Credential storage: Encrypted storage in Atlan's secure vault
Required permissions
| Role | Permissions | Purpose |
|---|---|---|
| Designer | Read access to projects, folders, and tasks | Metadata discovery and lineage extraction |
User account requirements
- Account type: Informatica Cloud user account
- Role assignment: Designer role minimum
- Access scope: Projects and folders containing target assets
Security considerations
- Credential encryption: All credentials encrypted at rest and in transit
- Token expiration: Automatic token refresh handling
- Audit logging: All authentication attempts logged
- Least privilege: Connector uses minimum required permissions
