10 SRE Fundamentals — SLIs, SLOs & Error Budgets

Description

Welcome to the SRE section — one of the most important parts of the exam. This video covers the core framework that Google invented for balancing reliability with innovation. You'll learn how to define Service Level Indicators (SLIs), set meaningful Service Level Objectives (SLOs), understand the legal weight of SLAs, and use error budgets to make data-driven decisions about when to ship features vs. when to focus on stability. This is the theory that underpins everything else in SRE. 🎯 What you'll learn: SRE philosophy: "what happens when software engineers run operations" Service Level Indicators (SLIs): choosing the right metrics Service Level Objectives (SLOs): setting realistic targets SLAs vs. SLOs: the business and legal distinction Error budgets: calculation, burn rate, and decision-making Error budget policies and stakeholder alignment The four golden signals: latency, traffic, errors, saturation 📚 This is Video 10 of 15 in the GCP Professional Cloud DevOps Engineer certification series. 🔬 Hands-On Lab Resources: Google Cloud Skills Boost — DevOps Engineer Learning Path: https://www.cloudskillsboost.google/paths/20 Coursera — SRE & DevOps Engineer Certificate: https://www.coursera.org/professional-certificates/sre-devops-engineer-google-cloud Google SRE Book (Free Online): https://sre.google/sre-book/table-of-contents/ SLO Generator Tool (GitHub): https://github.com/google/slo-generator #GoogleCloud #GCP #SRE #SLI #SLO #ErrorBudget #SiteReliability #Monitoring #DevOps
