Combination Active/Active High Availability + Disaster Recovery Site

While our active/active high availability (HA) patterns protect against node or availability zone outages, combining this pattern with a disaster recovery (DR) site can also help protect against a regional outage.

In this pattern, an active/active HA cluster handles the primary load in the primary data center or spreads across AZs in one region.

Then, at a DR site with a second data center or in a second region, you stand by ready to set up another active/active HA cluster in the event of a regional outage.

Combines With

• This pattern combines the Disaster Recovery Site and On-Prem Active/Active High Availability or Cloud Active/Active High Availability patterns.
• You can also combine this pattern with Federated Repositories as illustrated in Combination Active/Active High Availability + Disaster Recovery Site + Federated Repositories.
• Ensure you have perfected the Backup/Same-Site Restore pattern before combining it with more advanced patterns like this one.

Problems Addressed

• Data loss
• Data corruption
• DR across data centers
• DR across cloud regions
• Scalability
• Provides HA
