Microsoft Azure Database Integration with Appian Cloud

This page describes integrating a Microsoft Azure Database with Appian Cloud.

Supported options

Appian Cloud customers have the ability to connect to specific database options available in Microsoft Azure.

For Azure's SQL Database Managed Instances and SQL Server on Virtual Machines database options, customers must establish a private connectivity option when integrating with their Appian Cloud instance. You can use IPSec VPN Tunnels or Cloud Secure Link.

For Azure's fully managed databases, customers can integrate with any database compatible with the jdbc drivers listed in the supported data sources, for instance Azure SQL Database which runs with Microsoft SQL Server. Connectivity to this particular database must be established over the internet and customers can configure the data source in the Admin Console. Customers need to configure rules on their Azure Server Firewall to allow Appian Cloud IPs. As per Azure documentation, in-transit traffic to the database is encrypted using TLS.

Architecture

The diagram below shows three Appian Cloud instances integrating with Azure database resources using different connectivity options. Appian Cloud Instance A connects to an Azure SQL Database over the internet with TLS encryption. Appian Cloud Instance B connects to an Azure SQL Managed Instance over an IPSec VPN tunnel. Appian Cloud Instance C connects to an Azure SQL Managed Instance through Cloud Secure Link, which uses an mTLS-encrypted reverse tunnel and requires no inbound firewall ports on the customer side.
