Disaster Recovery & Geo-Replication

In the world of real-time data, ensuring continuous operation is paramount. What happens if an entire datacenter hosting your Kafka cluster goes offline?

• Disaster Recovery (DR): A plan to recover from major outages and resume critical business functions.
• Geo-Replication: Replicating data across geographically distant locations to protect against regional disasters.
• The goal is to minimize data loss (Recovery Point Objective - RPO) and downtime (Recovery Time Objective - RTO).

You've learned that Kafka topics are replicated across multiple brokers within a single Kafka cluster. This built-in replication protects against individual broker failures.

However, if an entire datacenter experiences a catastrophic event (e.g., power outage, network failure, natural disaster), this internal replication won't protect your data or services. All replicas in that datacenter would be lost.
