Transitioning from a self-hosted RabbitMQ cluster on EKS to a managed Amazon MQ setup, the organization aimed to alleviate the operational strain of managing complex messaging infrastructure and to focus more on core security feature development. The migration was driven by the need to eliminate RabbitMQ as a single point of failure and reduce the expertise required for troubleshooting. The process involved auditing existing services, mirroring configurations, and carefully orchestrating a "downstream-first" approach using Shovel plugins to ensure message continuity. Despite the challenges posed by over 50 service dependencies and zero-downtime requirements, the migration was executed without message loss, resulting in a more stable platform. The strategy emphasized the importance of comprehensive planning, visual mapping of dependencies, and maintaining parallel operations to manage risks effectively. The successful migration not only reduced the operational burden but also provided lessons in operational maturity and confidence in handling critical infrastructure transitions.
