• Site Reliability Engineering (SRE) has three foundational pillars: Availability & Reliability, Incident Response, and Observability.
• Availability & Reliability are about ensuring a system is functioning well and meeting customer expectations.
• Incident Response involves well-defined processes to manage system failures and learning from them to prevent repetitive issues.
• Observability is critical for SREs as it underpins the other pillars; SREs need to be expert users of observability platforms to understand key metrics, interpret data, and integrate this knowledge into their work.
• These pillars may vary across organizations, but they form the core skills and goals for all SREs.
