How Ksolves Enables Cross-Cloud Kafka Replication for Real-Time Data Resilience
A leading telecom client required uninterrupted, real-time data streaming across geographically distributed systems while ensuring disaster recovery and business continuity. To fulfill this need, Ksolves engineered a cross-cloud Kafka architecture leveraging Apache Kafka MirrorMaker 2, deploying Kafka clusters across AWS and Azure. This bidirectional replication setup ensures seamless data flow, high availability, and robust disaster tolerance, even in the event of regional or cloud-level disruptions.
During the project, our team faced several challenges while setting up cross-cloud Kafka replication:-
- Ensure real-time synchronization of data between Kafka clusters across two major cloud platforms.
- Maintain data consistency and availability in the event of partial or full cloud service disruptions.
- Minimize the latency and overhead introduced by replication processes.
- Secure cross-cloud communication without exposing services to vulnerabilities.
- Design an active-active architecture while avoiding replication loops or data conflicts.
- Design a disaster-tolerant Kafka infrastructure spanning multiple clouds.
To address these challenges effectively, our team implemented the following strategic solutions:
- Cluster Deployment: Set up Kafka Cluster-1 on AWS and Cluster-2 on Azure with configurations optimized for their respective environments.
- Bidirectional Replication: Used Kafka MirrorMaker 2 for real-time, bidirectional topic replication.
- Selective Topic Mirroring: Focused on key business topics (Topic-A, Topic-B, Topic-X, and Topic-Y) for replication to prioritize DR-critical data.
- Disaster Recovery Ready: Enabled cross-cloud failover, allowing consumer/producer redirection to the healthy cluster during outages.
- Replication Control: Applied granular replication filters and transformations to optimize performance and reduce unnecessary replication overhead.
- Security: Implemented secure communication and authentication across environments using TLS and access policies.
- Failure Testing: Conducted simulated cloud outages, network partitions, and broker failures to validate recovery time objectives (RTO) and data integrity.
- Achieved near-zero RTO and RPO, ensuring real-time failover without data loss.
- Delivered active-active Kafka architecture across AWS and Azure.
- Ensured data consistency, security, and availability under stress.
- Enabled real-time resilience for mission-critical telecom applications.
This active-active, cross-cloud Kafka deployment with MirrorMaker 2 established a robust DR strategy with near-zero RTO and RPO. The architecture supports seamless failover between AWS and Azure, maintains real-time data consistency, and ensures business continuity during infrastructure failures. It now serves as a resilient foundation for mission-critical applications, combining real-time streaming capabilities with enterprise-grade disaster recovery.
