What is SRE?
Site Reliability Engineering (SRE) is a modern discipline that blends software engineering, IT operations, and automation to make systems reliable, efficient, and scalable—especially for fast-changing technology businesses.
SRE is the application of engineering principles to operations and infrastructure tasks. It reduces manual work (“toil”) by automating monitoring, incident response, scaling, and deployment. SREs handle change management, performance tuning, capacity planning, and integrate reliability into every phase of the software lifecycle. They collaborate closely with development teams, manage error budgets, review post-incident reports, and drive improvements through data-driven processes.
SRE helps organizations deliver reliable digital services even as they grow quickly and release new features frequently. Adopting SRE reduces risk, limits costly outages, and increases customer satisfaction by ensuring systems are resilient and recover quickly from failures. SRE practices directly support business goals by optimizing resources, automating repetitive tasks for cost savings, planning for future growth, and orchestrating cross-team collaboration.
SRE is not only about avoiding downtime—it's about building a culture of reliability, accountability, and continuous improvement that benefits both technical and business stakeholders.
