In IT operations, the acronym SRE stands for which term?

• A. System Reliability Engineering
• B. Site Resilience Engineering
• C. Site Reliability Engineering
• D. Service Reliability Engineering

Answer: (C)

Site Reliability Engineering is the established term for the discipline that applies software engineering practices to operations to build scalable, reliable services. It focuses on reliability through measurable goals like SLOs and SLIs, uses error budgets to balance new features with stability, and relies on automation, robust monitoring, incident response, and capacity planning. This approach treats reliability as a product and aims to reduce toil while improving service resilience.

The other phrases are plausible but not the widely recognized term for this discipline, so the best answer is Site Reliability Engineering.
