What is Site Reliability Engineering?

Site Reliability Engineering is a discipline that applies software engineering to IT operations. Traditional system administration relies on manual server management. SRE treats infrastructure as a software problem.

Reliability means your system works correctly when users need it. Availability measures the total uptime of your service. Performance tracks how fast your system responds to requests. Monitoring lets teams watch system metrics in real time. Automation replaces manual tasks with reliable scripts and code.

Production systems require careful planning to prevent outages. Incident response helps teams fix unexpected failures quickly. For example, an SRE team might write a script to restart a failing service automatically instead of waking up an engineer at night.

What Does an SRE Engineer Do?

An SRE Engineer focuses on making production systems stable and scalable. Daily tasks depend on the specific organization and its tech stack.

Common responsibilities include:

• Monitoring live services and analyzing performance metrics.
• Managing alerts to reduce unnecessary notifications.
• Troubleshooting complex system failures during outages.
