Resolving Redis concurrency failures during a legacy .NET banking application's microservices migration

Banking Technology Services Firm

AceMQ supported the integration of Redis as a modern caching layer during the migration of a legacy banking application from monolithic architecture to microservices, resolving concurrency and timeout issues during the transition.

Overview

A banking technology services firm was decomposing a 10–15 year old monolithic .NET banking application into microservices. Redis was introduced as the central caching layer, but the team encountered unexpected timeout and concurrency issues as load increased during the transition period.

Challenge

The legacy application's connection and concurrency patterns were not designed for Redis client-side resource management in a microservices context. As new microservices came online and branch onboarding increased load, Redis timeouts cascaded into service failures that threatened the modernization timeline.

Environment

Legacy .NET monolith being decomposed to microservices; Redis introduced as new caching layer; cloud deployment; banking client with branch onboarding timeline.

Approach

AceMQ reviewed the Redis integration patterns across the microservices, identified connection pool misconfiguration and synchronous blocking patterns as the primary failure modes, and delivered targeted configuration changes and code-level recommendations.

Solution

  1. Connection pool configuration correction for .NET Redis clients in microservices
  2. Synchronous-to-asynchronous Redis access pattern refactoring guidance
  3. Timeout and retry policy tuning for production reliability
  4. Load testing support to validate fixes before branch rollout
  5. Operational monitoring recommendations for the modernized application

Outcome

AceMQ resolved the Redis integration issues ahead of the next banking branch onboarding cycle, enabling the modernization project to proceed on schedule and establishing stable Redis usage patterns for the remaining microservices migration.
