Business continuity through resilient messaging architecture

Overview

Mission-critical messaging systems require careful high availability and disaster recovery planning to ensure business continuity during infrastructure failures.

Challenge

HA/DR challenges include network partition handling strategy selection, quorum queue replication tuning, cross-AZ latency impact, backup/restore procedures, and federation/shovel-based replication between clusters.

Environment

Any RabbitMQ deployment requiring HA/DR capabilities — single-site, multi-AZ, or multi-region.

Approach

AceMQ designs HA/DR architectures tailored to specific RTO/RPO requirements, including cluster topology, partition handling strategy, backup procedures, and failover testing.

Solution

• Cluster topology design for target availability levels
• Partition handling strategy selection (pause_minority vs. autoheal)
• Quorum queue replication configuration for data durability
• Backup and restore procedures with metadata and message considerations
• Federation and shovel configuration for cross-cluster replication
• DR testing procedures and runbooks
