Allowing Atlan IPs in Databricks

Add Atlan's addresses to your Databricks workspace IP access list (or a corporate firewall in the path) so crawlers and miners can connect.

Allowlists and firewalls

Everything IP- and firewall-related for dbt - dbt Cloud's IP restrictions feature, and storage-side firewalls for dbt Core buckets.

Allowlists, firewalls & WAFs

The three gatekeepers that can sit between Atlan and Tableau - Tableau Cloud's IP allowlist, your firewall, and WAF content rules - and how to open each.

Atlan identity & network details

What identity Atlan presents to your AWS account for AWS Glue, which values are tenant-specific, and exactly what to request from support in a single ticket.

Atlan identity details

The Atlan-side values an Amazon S3 role setup needs, what each is for, and how to get them in a single support ticket.

Learn about the network identities Atlan presents to your data sources—public egress IPs, private CIDR ranges, and endpoint identities for AWS, Azure, and GCP tenants.

Choose how Atlan connects to Amazon Redshift

Compare the three ways Atlan can reach your Amazon Redshift cluster or Serverless workgroup - public IP allowlisting, the AWS private network link, and the self-deployed agent.

Choose how Atlan connects to dbt

Compare the two ways Atlan can read your dbt metadata - the dbt Cloud API with a token, or dbt output files in a cloud storage bucket for dbt Core.

Pick the network path and authentication method Atlan uses to reach Google BigQuery - public API endpoint or Private Service Connect, service account key or Workload Identity Federation.

Choose how Atlan connects to PostgreSQL

Compare the three ways Atlan can reach your PostgreSQL database - internet with IP allowlisting, private connectivity, or a self-deployed agent - and pick the right one before touching any firewall.

Compare the three ways Atlan can reach your Snowflake account—public IP allowlisting, Private Link, and the self-deployed agent—and pick the right one before you touch any cloud configuration.

Choose how Atlan connects to SQL Server

Compare the three ways Atlan can reach your Microsoft SQL Server - direct with IP allowlisting, a private network link, or the self-deployed runtime - and pick the right one before you touch any firewall.

Choose how Atlan connects to Tableau

Compare the four ways Atlan can reach your Tableau environment - direct, direct with IP allowlisting, AWS PrivateLink, and the self-deployed agent.

Connect directly with IP allowlisting

Connect Atlan to a SQL Server that is reachable from the internet - including Azure SQL Database with "Selected networks" enabled. Four phases, each labeled with who performs it.

Connect over the internet with IP allowlisting

The fastest path to connect Atlan to PostgreSQL - Atlan connects to your database's public endpoint over TLS, and you allowlist Atlan's fixed egress IPs. Five phases, each labeled with who performs it.

Connect through self-deployed runtime

Connect Atlan to a private AlloyDB for PostgreSQL instance with the self-deployed runtime - a small service in your network that reads AlloyDB locally and sends metadata out over outbound-only HTTPS.

Databricks connectivity

Troubleshoot Databricks connectivity, covering network and private-link issues, authentication, permissions, extraction, and metadata questions.

Firewall & IP allowlisting

Allow Atlan's fixed source IPs through your security group so crawlers and miners can connect to publicly accessible Amazon Redshift clusters and workgroups.

Firewalls and allowlists

SQL Server traffic from Atlan usually crosses several firewalls, owned by different teams. Every layer, which Atlan value belongs in each, and the mistakes that generate the most support tickets.

Firewalls, pg_hba.conf, and SSL

The reference for gates 1 and 2 - what to allowlist where, how pg_hba.conf decides, and how to keep the SSL settings on both ends consistent. Applies to every connectivity method.

How AlloyDB connectivity works

Learn why AlloyDB for PostgreSQL is hard to reach from outside, and what each of the three connection paths - self-deployed runtime, Private Service Connect, and public IP - actually does.

How Atlan connects to Databricks

Understand the three connectivity paths between Atlan and Databricks—public, Private Link, and site-to-site VPN—and what determines which one applies to your workspace.

How Atlan connects to Tableau

Learn the two Tableau APIs Atlan uses, how sign-in works with PATs and Connected Apps, and where Tableau connections typically get blocked.

How BigQuery connectivity works

Learn how Atlan reaches Google BigQuery, why there are no IP addresses to allowlist on the main path, and the four traffic hops that matter.

How Cloud SQL connectivity works

Learn the three traffic paths between Atlan and your Cloud SQL for PostgreSQL instance, who owns each piece, and why connectivity is not authentication.

How cross-account access works

Learn how Atlan reads your AWS Glue Data Catalog - the traffic path, the two ways of proving identity, and the two-key door that makes role-based access safe.

How cross-account access works

Learn how Atlan reads Amazon S3 - IAM roles, trust policies, External IDs, and the four AWS doors every crawl must pass through.

How database connectivity works

A plain-language explanation of the journey a connection makes from Atlan to your PostgreSQL database - the three gates it must pass, the three paths it can take, and SSL in one minute.

How dbt connectivity works

Learn the three traffic paths between your dbt setup and Atlan - the dbt Cloud API pull, the storage-bucket read, and your own upload pipeline.

How IAM role delegation works

Learn how Atlan borrows an identity in your AWS account for Amazon Athena, why there are two halves to set up, and the four traffic paths a healthy connection uses.

How private connectivity works

A plain-language explanation of what a private link to Databricks is, who builds which half, and the three traffic paths between Atlan and Databricks.

How private connectivity works

Learn what a private link is, who is responsible for each part of the setup, and the three traffic paths between Atlan and Snowflake.

How private network links work

Learn how Redshift-managed VPC endpoints work, who builds which half, and the three traffic paths between Atlan and Amazon Redshift.

How SQL Server connectivity works

A plain-language explanation of where Atlan's crawler actually runs, the three traffic paths to your SQL Server, and how authentication rides on top of the network path.

Network Connectivity Glossary

Definitions of the connectivity and identity terms used across Atlan's connector setup guides—endpoints, endpoint services, CIDR ranges, service principals, tenant settings, and more.

Private network links to Microsoft SQL Server

Connect Atlan to a SQL Server that has no public access, over AWS PrivateLink or Azure Private Link - one common five-phase pattern covering EC2, RDS, Azure VM, and Azure SQL Database / Managed Instance.

Private Service Connect to Cloud SQL

Keep traffic between your GCP-hosted Atlan tenant and your Cloud SQL for PostgreSQL instance entirely on Google's internal network with Private Service Connect.

PrivateLink connectivity

Understand how AWS PrivateLink ensures all metadata traffic between Atlan and AWS SageMaker Unified Studio stays within the AWS private network.

Set up Azure private connectivity to PostgreSQL

Private connectivity from Atlan to Azure Database for PostgreSQL is a support-assisted VNet peering setup - what to ask for, what you configure yourself, and the caveats to insist on before signing off.

Set up GCP private connectivity to PostgreSQL

Private connectivity to PostgreSQL on Google Cloud depends on what the database is - Cloud SQL and AlloyDB have Private Service Connect paths under their own connectors; self-managed Postgres uses the self-deployed agent.

Set up Google Private Service Connect

Keep Atlan's BigQuery API traffic off the public internet with Google Private Service Connect - Atlan builds the private endpoint; you paste one DNS name.

Set up Private Service Connect to AlloyDB

Let Atlan's SaaS reach your AlloyDB for PostgreSQL privately over Google's internal network - no public IP, nothing deployed on your side beyond a service attachment.
