Enhanced Business Continuity for Appian Cloud

Enhanced Business Continuity is available for purchase only to customers that are on Advanced or Enterprise Support and their environment is located in a US commercial or GovCloud region. This feature needs to be purchased separately to Advanced or Enterprise Support.

Overview

When Enhanced Business Continuity is enabled, Appian stores backups of your Appian Cloud production environment in a secondary geographical region, within the US, for disaster recovery purposes. This feature is in addition to the standard Appian Cloud backup policy.

With this feature you have a guaranteed recovery point objective (RPO) in the event of a region-wide failure where your environment is located. In such an event, the environment will be restored using backups in the secondary region.

For example, if your environment is located in Northern Virginia you can choose to store additional backups in the Ohio region or vice versa.

Service level agreements

When Enhanced Business Continuity is enabled, you have a guaranteed recovery point objective (RPO) of 4 hours in the event of a region-wide failure where your environment is located.

Prerequisites

  • Your environment must be located in a US commercial or GovCloud region.
  • You must have purchased Advanced or Enterprise Support.
  • You must have a purchase order for Enhanced Business Continuity. Note this feature needs to be purchased separately to Advanced or Enterprise Support.
  • Your Appian Cloud environment must not use Bring Your Own Key (BYOK) with AWS KMS since BYOK with KMS depends on region-specific resources hosted in the same region as your environment.

    Appian supports BYOK with AWS CloudHSM with Enhanced Business Continuity. However, you are responsible for providing a backup of the HSM located in another region. The HSM backup must be available in the event of a region-wide failure where your environment is located.

Available regions

Your environment must be located in a US commercial or GovCloud region. See Appian Cloud Exclusive Feature Support for more information about these regions and the Appian Cloud features that they support.

Commercial regions

For environments located in a US commercial region, backups are stored in a different US commercial region than where the main environment is located. The US commercial regions are:

  • Northern Virginia
  • Ohio
  • Oregon
  • Northern California*

*High Availability customers cannot use Northern California as the backup region.

For improved recovery time, we recommend locating your main environment in Ohio, Oregon, or Northern California.

GovCloud regions

For environments located in a US GovCloud region, backups are stored in the region that the main environment is not in. The US GovCloud regions are:

  • GovCloud (US East)
  • GovCloud (US West)

For a full view of all Appian Cloud regions and other information, visit the Appian Trust Center.

Steps

Once the prerequisites have been completed, follow these steps to enable Enhanced Business Continuity for your Appian Cloud environment:

  1. Work with Appian Support via a Support case to enable this configuration in your Appian Cloud environment.
  2. Provide the preferred secondary backup region to Appian Support via the Support case.
  3. Appian Support will enable Enhanced Business Continuity for your production environment.

Recovery procedure

In the event of a region-wide failure where your environment is located, Appian Support will restore the environment in the secondary region where the backups are located.

When an environment is restored in the secondary region, integration points between the environment and any resources or services external to Appian Cloud will need to be updated if the integrations use region-specific resources. Integration points which use region-specific resources include:

Appian Support will work with you to update the configurations for any integration points that are affected.

FAQ

Why is Enhanced Business Continuity only available in US regions?

Currently the US is the only country with multiple Appian Cloud commercial and GovCloud regions. Therefore, it is the only location where backups to a secondary region are possible, while ensuring your data remains in the same country.

What is the Recovery Time Objective (RTO) for Enhanced Business Continuity?

Currently there is no guaranteed RTO for this feature.

Does Enhanced Business Continuity cover all of my Appian Cloud environments?

This feature is available for purchase on a per-environment basis.

What is the difference between High Availability (HA) and Enhanced Business Continuity?

Appian Cloud HA reduces the risk of an unplanned outage due to a hardware failure or due to an incident affecting an entire AWS availability zone, however all data is still stored in the same geographical region. Enhanced Business Continuity stores additional backups in a secondary region, reducing the risk of business disruption due to a region-wide failure.
