System Requirements


When using Appian, your system must meet the following minimum requirements.

Operating Systems

This table lists the supported platforms for servers that host Appian.

Linux (Reference Platforms) Windows
Red Hat Enterprise Linux Windows Server 2012
CentOS Windows Server 2008
Ubuntu Windows 7


  • Due to the way file names and file paths are calculated for documents stored in Appian, the application server and engine servers must use the same type of operating system. Do not mix Windows and Linux.
  • Customers who wish to run VMware must use one of the platforms listed above as the guest operating system.
  • Only 64-bit operating systems running on x86-64 CPU architecture (sometimes referred to as x64) are supported.

Application Servers

The table below lists the supported application servers.

Supported Application Servers Supported JDK Comments
JBoss Enterprise Application Platform 6.4 (6.4.14 or later) Oracle Java JDK 1.8.0_x (update 92 or later) The latest minor version of JBoss EAP 6.4.x is required for production and recommended for non-production.
WebLogic Server 12c R2 (12.2.1.x) Oracle Java JDK 1.8.0_x (update 92 or later) WebLogic Server 12c R2 patch version or later is required in order to avoid a classloader bug that can prevent system startup.

Note: Due to the potential for unintended interactions and resource contention when deploying multiple enterprise application archives (EARs), Appian requires the Appian EAR be the only application (EAR or WAR) deployed on the production application server.

Hardware Requirements

The table below describes the recommended minimum physical system requirements. The RAM and hard disk requirements are in addition to any system memory used by other applications and by the operating system.

Systems RAM (GB) Hard Disk (GB) Processor Cores or CPUs
Client workstations 2 Web Browser 1
Appian Designer client workstations 4 Web Browser 1
Machines hosting the application server 4 50 2
Machines hosting Appian engines 4 50 2

Your actual requirements may vary. Given that Appian utilizes an in-memory database, use the sizing script to help project the RAM that will be required for your installation.

Cloud Infrastructure as a Service

For customers who wish to run Appian from cloud infrastructure as a service, Appian will run on any that support the operating systems, application servers, and minimum hardware requirements as listed in this article.

The following major providers of cloud infrastructure as a service are known to be compatible with Appian:


The following relational database management systems (RDBMS) are supported as the Appian data source data source and as business data sources.

RDBMS Driver
MySQL 5.7.x (on latest patch) with InnoDB engine Connector/J 5.1.x (on latest patch)
MySQL 5.6.x with InnoDB engine (deprecated) Connector/J 5.1.41 (or later)
Oracle 12c R1 Oracle Thin JDBC Driver for 12c R1
(with patch for Oracle bug 19632480)
Oracle 11g R2 Oracle Thin JDBC Driver for 11g R2
Microsoft SQL Server 2014 Microsoft JDBC SQL Server Driver 4.2 (or later)
Microsoft SQL Server 2012 Microsoft JDBC SQL Server Driver 4.2 (or later)
Microsoft SQL Server 2008 Microsoft JDBC SQL Server Driver 2.0 and 4.2 (or later)
IBM DB2 UDB v9.7 for Linux, UNIX, and Windows IBM DB2 JDBC Driver version 4.9.78

In addition to these databases, other databases not listed here are also supported for use with the Query Database Smart Service, as long as the database provides a JDBC compliant database driver.

Note: Appian recommends a round-trip time for TCP communications between the application server and database of less than 10 milliseconds with an upper bound of 25 milliseconds for acceptable performance. Network latency outside of these bounds will result in degraded system performance.

Web Browsers

The supported Web browsers are listed in the table below. Use the Appian for Mobile Devices application for iOS and Android instead of mobile browsers. See Mobile Devices for more information.

Web browsers must allow cookies. If a user's browser is not configured to allow cookies, then Appian displays an alert stating that cookies must be enabled in order to log in.

Browser Comments
Microsoft Edge Microsoft Edge is only supported on Windows 10 operating systems.
Microsoft Internet Explorer 11

Microsoft Internet Explorer 11 is supported on Windows operating systems.

Microsoft Internet Explorer 11 is supported on Windows 8.x tablet.

Running Internet Explorer in Enterprise or Document Mode to emulate older browser versions is not supported.

Mozilla Firefox Mozilla Firefox updates automatically. Appian supports the most recent stable version of Mozilla Firefox.
Google Chrome Google Chrome updates automatically. Appian supports the most recent stable version of Google Chrome.
Apple Safari Safari is only supported on Mac operating systems.

Note: Appian does not support browsers that are no longer supported by their vendor. Use the latest supported browser version and always apply all available security updates.

Web browsers for Appian Cloud users should be configured to allow TLS version 1.1 and/or 1.2 as Appian Cloud sites will drop support for TLS 1.0 in a future release. See KB-1064 for more detail.

Appian Feature Support by Browser

The table below lists browser compatibility by feature. Certain features in Appian, such as the Process Modeler, have their own browser configuration requirements. See Web Browser Configuration for more information.
