Site Reliability Engineering (SRE) is an increasingly critical discipline in the modern DevOps environment. Originated at Google in 2003, this methodology proposes treating operations as if they were software problems. According to a recent article published by IBM, there are seven fundamental principles that guide teams toward operational success.

It is important to highlight that, according to the authors of Google’s SRE guide, between 40% and 90% of the total costs of a system are incurred after its creation. Therefore, SRE focuses on maximizing the utility and stability of the product throughout its lifespan.
