Reliability and SRE Concepts
Learn the principles that keep systems running smoothly in production. You'll understand SLOs, error budgets, incident response, and building resilient systems.
6 lessons
What Is Site Reliability Engineering?
Site Reliability Engineering applies software engineering principles to operations, balancing system reliability with development velocity.
SLIs, SLOs, and SLAs
Learn how Service Level Indicators, Objectives, and Agreements work together to define and measure system reliability.
Error Budgets
Error budgets quantify acceptable unreliability, helping teams balance shipping features against maintaining stability.
Incident Management
Learn how to respond effectively when things go wrong, with clear roles, processes, and communication strategies.
Postmortems and Learning
Blameless postmortems turn incidents into learning opportunities, preventing the same problems from recurring.
Building Reliability Culture
Sustainable reliability requires cultural practices that make it everyone's responsibility, not just the operations team's job.
