Title: Key Principles of SRE

• Service Level Objectives (SLOs): SRE focuses on defining and measuring specific targets for reliability, performance, and other critical aspects of a service. SLOs provide a shared understanding between developers and operations teams about acceptable levels of service quality.
• Automation: SRE emphasizes automation to reduce manual toil, minimize human error, and improve operational efficiency. Automating repetitive tasks enables teams to focus on higher-value work and innovation.
• Incident Response: SRE teams are responsible for monitoring and responding to incidents in a systematic and proactive manner. Incident management processes, such as post-incident reviews (PIRs), help identify and mitigate underlying issues to prevent future incidents.
