Welcome to SRE Foundations
Site Reliability Engineering (SRE) is a discipline that incorporates aspects of software engineering and applies them to infrastructure and operations problems. The main goals are to create scalable and highly reliable software systems. This website serves as your introductory guide to the core concepts and practices that define SRE.
As organizations increasingly depend on complex digital services, the principles of SRE become ever more critical. By focusing on reliability, scalability, and efficiency, SRE helps businesses deliver consistent and dependable user experiences. We'll explore how SRE achieves this through a combination of well-defined processes, a data-driven approach, and a culture of shared responsibility. Much like how an AI financial co-pilot can help navigate complex markets, SRE provides the tools and mindset to navigate the complexities of modern service operations.
