The Site Reliability Engineering (SRE) Mindset: Reliability through Engineering and Culture
  Introduction Site Reliability Engineering (SRE) is a discipline that applies software engineering principles to IT operations in order to create highly stable and scalable systems. As Google’s Ben Treynor (who founded SRE at Google) famously described: “SRE is what happens when a software engineer is tasked with what used to be called operations.” In practice, this means approaching traditional ops work with an engineering mindset – building tools and automation to manage systems, measuring and treating reliability as a feature of the product, and continually improving processes. The SRE mindset shifts teams from reactive “firefighting” to proactive resilience engineering, making reliability a first-class concern rather than an afterthought in software services. This article explores the core principles of the SRE mindset and how they benefit developers, operations engineers, and technical managers alike. We will discuss why reliability is considered a feature of the product, how...
