Implementing circuit breakers ensures critical interventions are possible during system slowdowns, preventing cascading failures across systems. To enhance resilience, decouple critical systems so they operate independently, mitigating the risk of a single point of failure affecting the entire architecture. Using queuing systems, such as RabbitMQ or ZeroMQ, can effectively manage data flow between these decoupled systems, allowing them to function without overwhelming each other and providing a buffer through which they can communicate efficiently.
