Site Reliability Engineering (SRE) is a practice that uses software to automate tasks traditionally carried out by operations teams, such as managing systems and solving problems. SRE helps development teams accelerate reliable software delivery by reducing duplication of effort, providing feedback loops for measuring operations, and automating tasks. An SRE team can be used for change management, application monitoring, emergency response, and site reliability. The ideal SRE is a proactive problem solver with an investigative nature, experience finding problems in software, and confident coding skills. SRE focuses on automation, reducing manual work, and providing feedback loops to measure operations through consistent processes. By employing SRE, teams can improve collaboration, customer experience, efficiency, security, and deployment timing, while also executing tests at the right time, resolving issues quickly, and managing risk visibility across the software development lifecycle.
