Reliability Engineering: SLIs, SLOs and Error Budgets Overview
The Reliability Engineering: SLIs, SLOs and Error Budgets Training Course is a practical, hands-on program designed for IT operations, Site Reliability Engineering (SRE), DevOps, cloud, and software engineering professionals who are responsible for ensuring the reliability, availability, and performance of modern digital services. The course introduces the core principles of Site Reliability Engineering (SRE) and demonstrates how Service Level Indicators (SLIs), Service Level Objectives (SLOs), and Error Budgets are used to balance system reliability with the pace of innovation.
Participants will learn how to define meaningful service reliability metrics, establish measurable reliability objectives, monitor service health, manage operational risks, and use error budgets to guide deployment decisions and continuous improvement. Through real-world case studies, practical workshops, and hands-on exercises, participants will gain the skills required to implement reliability engineering practices across cloud-native, distributed, and enterprise IT environments.
Duration 3 Days – 21 hrs.
