What does it really take to turn cloud cost chaos into a sustainable FinOps practice, and why do most organizations get it wrong from the start?

In this episode of FinOps in Action, I sit down with Loic Fournier, Senior Technical Account Manager at AWS and 2025 AWS Technical Field Community Legend. With over 25 years in technology, from mainframes to modern cloud, Loic has become one of the most recognized voices in AWS cost optimization.

Loic shared how the biggest mistake organizations make is treating FinOps as a one-time project rather than an ongoing practice, and what it actually takes to build governance that sticks across people, processes, and technology.

We also covered the AWS native tools available to every organization for free, the link between cost optimization and sustainability, and how AI workloads are reshaping FinOps priorities heading into 2026.

Here’s what we talked about:

• Why FinOps fails when treated as a project
• The three pillars of FinOps governance
• How to get executive buy-in
• AWS free tools you should activate today
• The hidden savings hiding in your EBS volumes
• FinOps as a proxy for sustainability
• Managing AI costs before they spiral
