High Availability for Appian Cloud

Appian Cloud offers the ability to run in a high-availability (HA) configuration. An HA configuration protects your Appian instance from downtime in the event of a service failure (a software component of Appian fails), a server failure (the hardware that Appian runs on fails), or an AWS availability zone failure (the data center that Appian runs in fails).

This is achieved by replicating data across three AWS availability zones.

When running in a high availability configuration, an Appian Cloud site has a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 15 minutes. This means that in the event of a system failure, your Appian instance will be back online and available to your users in less than 15 minutes, having lost no more than the last 15 minutes worth of data.

The high availability configuration is available in the Frankfurt, Ireland, Ohio, Oregon, Sydney and Virginia regions.

To change your Appian Cloud instance to an HA configuration, contact your account executive.
