Why SLOs are so important?
- Improve software quality SLOs help define an acceptable level of downtime for a service or a particular issue. SLOs can help on issues that fall short of a full-blown incident, but also don’t fully meet expectations. Using SLOs can help to figure out the balance between innovating (which could result in downtime) and delivering (which ensures users are happy).
- Help with decision-making SLOs can be a great way for DevOps and infrastructure teams to use data and performance expectations to make decisions. Why are SLO’s important ?
- Promote automation Stable, well-calibrated SLOs pave the way for teams to automate more processes and testing throughout the software delivery life cycle (SDLC). With reliable SLOs, it is possible to set up automation to monitor and measure SLIs and set alerts if certain indicators are trending toward violation. This consistency enables teams to calibrate performance during development and detect issues before SLOs are actually violated.
- Avoid downtime It is inevitable that software can break. SLOs allow DevOps teams to predict the problems before they occur and especially before they impact customers. By shifting production-level SLOs left into development, it is possible to design apps to meet production SLOs to increase resilience and reliability far before there is actual downtime. This trains teams to be proactive in maintaining software quality and saves money by avoiding downtime.
