Protection from Disaster

In the event of a disaster, users can lose access to services that are critical to their jobs. As a result, these users cannot provide services to other users. The ability to restore access to services depends on the remote installation of CA CloudMinder at a site that is called the Disaster Recovery (DR) site.

The primary site and DR site run in a hot/warm configuration.

• All customer traffic goes to the primary site until a failure occurs. At that point, traffic is manually switched to the DR site.
• The DR site is a clone of the primary site with certain exceptions as described below. The DR site may or may not be internally redundant. This choice is made based on availability and cost considerations.

Server activity at the DR site varies by tier.

• In the data tier, CA Directory and the database are active to support data replication from the primary site.
• In the web tier and application tier, all functions are dormant except for CA IAM Connector Server. This dormant mode is necessary for applications that access the database (for reasons explained below). Although the web tier does not directly access the database, it cannot function without the application tier.
