In 2023, the software landscape is increasingly complex, with distributed teams, large codebases, and elaborate test suites, all of which are managed using Continuous Integration and Continuous Deployment (CI/CD) systems that promise reliable and frequent code delivery. However, issues such as flaky tests and slow build times often undermine confidence in these systems. To address these challenges, Site Reliability Engineering (SRE) principles, which emphasize reliability through measurement and observability, can be applied to CI/CD processes. By utilizing Service Level Objectives (SLOs), Service Level Indicators (SLIs), and Error Budgets, teams can set clear expectations and metrics for system reliability, allowing for improved focus and reduced developer frustration. These tools help prioritize the maintenance of key systems, ensuring they are reliable enough to meet user needs without striving for unattainable 100% reliability. Implementing these practices can restore trust in CI/CD systems, allowing for smoother operations and enabling teams to confidently deploy changes, even on a Friday afternoon.
