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.

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.

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.

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.

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.

Special cases

On-premises SQL Server via the self-deployed runtime, Windows/NTLM and Entra ID authentication quirks, Azure SQL Managed Instance failover listeners, and estates with many environments and ports.

Troubleshooting SQL Server connectivity

Symptom-first troubleshooting for Microsoft SQL Server connectivity - HYT00 login timeouts, 08001 handshake resets, TCP failures and redirects, authentication errors, private link stalls, and agent hangs.
