Tight coupling occurs when upstream changes, such as bug fixes or new releases, directly affect downstream systems, leading to instability and integration challenges.
EMTECH recommends maintaining clear Service Level Agreements (SLAs) to ensure consistent uptime and predictable service continuity. Providers should also decouple transactional and reporting logic to prevent disruptions in one system from affecting another.
For example, service providers can publish transaction events to RabbitMQ, allowing subscriber services to handle reporting asynchronously. Alternatively, they can schedule periodic jobs that batch transactions over a defined reporting period and send them in aggregate, reducing dependency on real-time synchronization and improving overall system resilience.
