Why is SRE Critical for High-Availability Systems in 2026?
Site Reliability Engineering is a practice that combines software engineering and IT operations to build, run, and maintain scalable and reliable systems. Originally developed to address the growing complexity of large-scale infrastructures, SRE focuses on automating operational tasks, improving system observability, and reducing downtime.
Rather than reacting to incidents after they occur, SRE teams proactively identify risks, optimize performance, and ensure that applications meet predefined reliability targets.
