SRE teams focus on automating manual tasks, monitoring system health, managing incidents, and improving service uptime. They use metrics like Service Level Indicators (SLIs), Service Level Objectives (SLOs), and Error Budgets to maintain a balance between innovation and system stability.

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