- 3. Introduction SRE foundation certification Site Reliability Engineering (SRE) is a discipline that combines software engineering and IT operations to ensure high reliability, availability, and performance of large-scale systems.
- 4. Embrace Risk Use Error Budgets Define Service Level Indicators Start by identifying key performance metrics (e.g., latency, availability, error rate) that reflect user experience. Prioritize Reliability nitor Continuously Set Realistic SLOs Foster a Blameless Culture Calculate the acceptable margin of failure (e.g., 0.1% downtime for 99.9% availability). This "error budget" helps teams balance reliability with innovation When error budgets are consumed, shift focus from releasing new features to improving system stability. Establish Service Level Objectives as specific targets for your SLIs (e.g., 99.9% uptime). These should align with business goals and customer expectations. Track performance data in real time to ensure systems are within the defined SLOs. Use SLO breaches as learning opportunities rather than reasons for blame, encouraging collaboration and continuous improvement.
- 5. LOGGING TOOLS Jenkins, GitLab CI, CircleCI – Automate code integration, testing, and deployment. TOOLS COMMONLY USED IN (SRE) ELK Stack (Elasticsearch, Logstash, Kibana), Fluentd, Splunk – Collect, process, and analyze logs to identify system issues. CI/CD PIPELINES Istio, Linkerd – Manage service-to-service communication, security, and observability in microservices. SERVICE MESH
