Observability
Ability to understand how systems behave, why they behave that way, and what impacts their performance based on the outputs it produces.
Observability has become a critical discipline in modern software engineering, representing the ability to understand the internal state of a system based on the external outputs it produces. As applications have evolved from monolithic architectures to complex, distributed microservices running across cloud environments, traditional monitoring approaches have proven insufficient for understanding system behavior and diagnosing issues.
True observability goes beyond simple monitoring and logging—it provides comprehensive insight into how systems behave, why they behave that way, and what impacts their performance. This depth of understanding is essential for maintaining reliable, performant applications in today's complex technological landscape.
