Site Reliability Engineering (SRE)

Overview

What if you could measure reliability like a software feature? Site Reliability Engineering, or SRE, is the practice that bridges operations and development, ensuring systems are both highly available and scalable. Used by companies managing complex, high-traffic services, SRE focuses on defining and meeting service-level objectives through automation, monitoring, and continuous improvement. Visualizing SRE often includes a diagram showing the balance between reliability and speed, with error budgets guiding decisions. To apply SRE, teams set clear goals, automate operations, and foster a culture of ownership and collaboration. In a world where downtime is costly, SRE turns reliability into a measurable, achievable target.
