-Uncover the critical aspects of system availability, from key metrics and failure analysis to design strategies that ensure reliability and uptime.
+In this article, we provide a bird's eye view of designing for system availability. We'll cover the essentials: from understanding availability metrics and dissecting failure modes to applying core design principles. This overview offers a foundational understanding of how to achieve and maintain high system reliability and uptime.
 
 ## Availability Metrics
 Availability metrics are crucial in system design, serving as benchmarks for reliability and uptime. These metrics, often expressed as percentages, indicate the proportion of time a system remains operational under normal conditions. The gold standard is the 'five nines' - 99.999% availability, translating to just over five minutes of downtime per year. By regularly monitoring these metrics, engineers can identify trends, predict potential downtimes, and implement proactive measures to enhance system resilience.
