Site Reliability Engineering (SRE) works hand-in-hand with Agile by keeping systems reliable while teams move fast. Practices like automation, monitoring, incident response, and setting service-level objectives (SLOs) help maintain performance without slowing development. By collaborating closely, sharing ownership, and using tools like Prometheus, Grafana, and Jira, SRE and Agile teams can balance speed, flexibility, and reliability, even while managing trade-offs between rapid delivery and system stability.
