System Design] Reliability vs. Availability

Software systems must provide users with reliable and continuous service . Two key concepts at the heart of this goal are Reliability and Availability . Many people confuse these terms or use them interchangeably. However, in system architecture, it is crucial to understand the difference and consider them separately . 1. Reliability How long does the system operate without failure? Definition Reliability refers to a system’s ability to operate continuously without errors . In other words, once the system starts, how long can it run without interruption or failure? Key Concepts MTBF (Mean Time Between Failures): The average time between two consecutive failures. Fault Tolerance: The system should continue to function even if one component fails. Example A server operates flawlessly for 180 out of 365 days , then experiences a critical failure and remains down for 2 days . → High reliability (long stable period), but low availability (long downtime when it fail...
