Service discovery plays a crucial role in architecturally resilient systems. It allows different components of the system to find and communicate with each other dynamically, without hard-coding IP addresses or other specific details. In a resilient system, service discovery enables automatic failover and load balancing, as well as the ability to scale up or down by dynamically adding or removing services. In addition, service discovery ensures that the system can adapt to changes in the underlying infrastructure, such as new servers or network topology changes, without requiring manual intervention or downtime. Overall, service discovery is an essential component of an architecturally resilient system that provides the flexibility and adaptability required to handle unexpected failures and maintain high availability.
