Microservices offer numerous advantages, such as language flexibility, scalability, and system robustness, making them an attractive architectural choice for software development. Each service can operate independently, allowing for easy replacement and scaling without affecting other services. However, if not managed properly, microservices can lead to significant issues, as illustrated by a scenario where a bug in a microservice causes slow processing and failure in auto-discovery, leading to an uncontrolled increase in service instances until system resources are exhausted. This highlights the importance of implementing robust logging and monitoring practices to detect issues early, such as periodic health checks and resource limits, to prevent such problems and maintain system efficiency and stability.
