The Most Expensive Mistakes in Cloud Infrastructure

Julia Lamenza
Consultant
Abstract

Cloud platforms make it incredibly easy to deploy infrastructure in minutes, but they also make it surprisingly easy to create costly mistakes that quietly inflate cloud bills and reduce system reliability. In this talk, I will explore some of the most common and expensive mistakes teams make when running cloud infrastructure at scale. Drawing from real-world SRE experience operating cloud-native systems, this session highlights practical examples of how these issues appear in production environments and how teams can identify and avoid them. Attendees will leave with a better understanding of the hidden pitfalls in cloud infrastructure and practical strategies to build systems that are not only reliable, but also cost-efficient.

Bio
