Disaster Recovery deployment model
The Disaster Recovery (DR) deployment model uses high availability (HA) clusters distributed over a geographic area.
Disaster Recovery (DR) is a method where two high availability (HA) data center configurations are separated geographically. The extra benefit here from a single location HA configuration is that in the event of a localized disaster, the physically removed data center resumes functions with minimum downtime.
Prerequisites
- Enable the inbound and outbound ports.
- Add all the hostnames in the host file entries for all the nodes.
- Ensure that the primary and secondary databases are in sync.
- Automation Anywhere Control Room and IQ Bot must be installed on both primary (active) and secondary (passive) DR sites.
- While switching between the primary and secondary servers, ensure the
following:
- If the secondary database has read-only permission, the primary database has read/write permission.
- If the secondary database has read/write permission, the primary database has read-only permission.
The following diagram shows the IQ Bot DR setup:
In this example, all the servers have redundancy.
- Multiple users have access the IQ Bot cluster through their web browsers. The web browsers communicate to the IQ Bot clusters through the load balancers.
- Multiple Bot Runners communicate to their IQ Bot cluster through the load balancer.
- The server message block (SMB) file share and the Microsoft SQL Server store data from their IQ Bot cluster. Both servers are asynchronously replicated to the backup disaster recovery site.
- Microsoft SQL Server uses redundancy through replication syncing to the clustered Microsoft SQL Server on the primary disaster recovery site.
For disaster recovery in IQ Bot environment.
-
Deploy a second IQ Bot HA cluster in an additional data center that is in a separate geographic location.
-
In the event of a primary site failure, do the disaster recovery manually. See Disaster recovery failover steps overview.
Note: When a failover to a backup site occurs, it is possible that very recent changes made on the primary site are lost.
- Pros
- Provides business continuity when faced with data center outage or loss.
- Cons
- Increased operational burden.
