Non-Functional Requirements For The Win!

In today’s fast-paced world of distributed applications and cloud-native architectures, ensuring system stability goes beyond just writing good code—it requires a strong focus on Non-Functional Requirements (NFRs). This session explores the role of NFRs in delivering reliable, performant, and scalable systems, with a deep dive into the critical trio of Service Level Indicators (SLIs), Service Level Objectives (SLOs), and Service Level Agreements (SLAs).

We will discuss how well-defined SLOs drive operational excellence, enabling teams to proactively manage system performance, latency, and availability. You’ll learn how to set realistic SLOs, measure against SLIs, and balance trade-offs between reliability and agility. Whether you’re responsible for a single application or an enterprise-wide platform, mastering NFRs will set you up for long-term success.

This talk also provides real-world examples of how teams transition from reactive SLAs to proactive SLOs, ensuring their systems meet customer expectations while optimizing infrastructure costs.
