  1. SLIs, SLOs, and SLAs in Modern Cloud-Native Systems (2025) Understanding the Role of Service Metrics in Cloud Operations +91-7032290546 www.visualpath.in

  2. Introduction to SLIs, SLOs, and SLAs • Definition: • SLI (Service Level Indicator): Quantitative measure of system performance (e.g., response time, error rate). • SLO (Service Level Objective): A target value or range for an SLI (e.g., 99.9% uptime). • SLA (Service Level Agreement): A formal contract specifying the SLOs between a service provider and customer. • Purpose: These are critical for monitoring and ensuring reliable service delivery. +91-7032290546 www.visualpath.in

  3. SLIs in Cloud-Native Systems • SLIs in Cloud Context: • Track specific metrics like latency, error rates, availability, throughput, and resource utilization. • Examples: • Request latency in an API. • 5xx errors in microservices. • Database query response times. • Tools Used: Prometheus, Datadog, Grafana, OpenTelemetry. +91-7032290546 www.visualpath.in

  4. SLOs in Cloud-Native Systems • SLOs Defined: • Service level objectives represent desired performance thresholds for SLIs. • Example: "Service should have an uptime of 99.95% over a month." • Importance of SLOs in Cloud: • Align engineering teams with reliability goals. • Helps prioritize reliability investments (e.g., scaling, failover strategies). • Should be based on user expectations and experience. • Example SLOs: • "API latency < 200ms 99% of the time." • "95% of transactions are processed successfully." +91-7032290546 www.visualpath.in

  5. SLAs in Cloud-Native Systems • SLAs Explained: • Legal agreements between customers and service providers. • Define penalties or remediation when SLOs are not met. • In 2025 Cloud Context: • Frequently associated with cloud providers (e.g., AWS, GCP, Azure). • Incorporates cloud-native architectures like containers, microservices, and serverless. • Importance: Ensures trust and reliability in service contracts. +91-7032290546 www.visualpath.in

  6. Relationship Between SLIs, SLOs, and SLAs • Diagram: A flowchart or Venn diagram linking SLI, SLO, and SLA: • SLI is the data you measure. • SLO is the goal or target for that data. • SLA is the formalized agreement outlining SLOs and penalties. • How They Interact in Cloud-Native Systems: • SLIs provide the data to evaluate if SLOs are being met. • SLAs formalize expectations with customers, backed by SLOs. +91-7032290546 www.visualpath.in

  7. SLIs, SLOs, and SLAs in Microservices and Serverless Environments • Microservices Impact: • Each service has its own SLIs and SLOs. • Communication between services can impact SLIs (e.g., inter-service latency). • Serverless Context: • SLOs for serverless applications are often related to invocation success rates, execution duration, and cold start times. • SLIs must adapt to the stateless, dynamic nature of serverless workloads. +91-7032290546 www.visualpath.in

  8. Challenges in Setting SLIs, SLOs, and SLAs • Challenges: • Defining Useful SLIs: Ensuring SLIs are aligned with actual user experience and business objectives. • Balancing SLOs: Too aggressive may lead to over-provisioning; too lenient may hurt customer satisfaction. • Monitoring & Observability: Continuous real-time monitoring with tools like Prometheus and Grafana to track SLIs. • Cloud-Specific Considerations: • Dynamically scaling environments can cause fluctuations in SLO compliance. • Global distributed architectures add complexity to measuring SLIs accurately. +91-7032290546 www.visualpath.in

  9. Best Practices for Implementing SLIs, SLOs, and SLAs in 2025 • Best Practices: • Define Clear User-Centric SLIs: Focus on metrics that matter to end users (e.g., load times, error rates). • Continuous Measurement & Alerting: Use automated tools for real-time monitoring (e.g., Prometheus, New Relic). • Iterate on SLOs: Review and adjust SLOs based on changing user expectations and system performance. • Maintain Transparency: Communicate failures and improvements with stakeholders through well-defined SLAs. • Cloud-Native Tools: Leverage cloud-native solutions (e.g., Kubernetes, service meshes) to automatically track and scale SLIs/SLOs. +91-7032290546 www.visualpath.in
