In cloud-native environments, which persona is typically responsible for managing Service Level Agreements (SLAs), Service Level Indicators (SLIs), and Service Level Objectives (SLOs)?

• A. DevOps Engineer
• B. Site Reliability Engineer (SRE)
• C. Cloud Architect
• D. Platform Engineer

Answer: (B)

The responsibility for defining and maintaining SLAs, SLIs, and SLOs sits with the Site Reliability Engineer. SREs focus on reliability and the measurable targets that determine whether a service is meeting its commitments. An SLO is a target for a specific aspect of service performance (for example, uptime of 99.9% or a maximum p95 latency), an SLI is the metric used to measure that aspect (like availability or latency), and an SLA formalizes these expectations and any remedies if targets aren’t met. In cloud-native environments, SREs translate these targets into concrete monitoring, alerting, incident response, and capacity planning, using error budgets to balance reliability with delivery speed. Other roles play important parts, but their primary focus isn’t owning reliability targets in production. A DevOps engineer typically concentrates on automation and CI/CD pipelines; a cloud architect designs the overall cloud structure and governance; a platform engineer builds the internal platform to enable development. The SRE role uniquely centers on defining, measuring, and enforcing reliability targets across services, making it the best fit for SLAs, SLIs, and SLOs.
