Moving from "Guessing" to SAVING ft. Loic Fournier, AWS
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
Quote of the Show:
“FinOps is a proxy for sustainability. When you help a customer perform better in FinOps, you are also helping save the world a little bit.”- Loic Fournier

In this episode of FinOps in Action, Loic Fournier shares how his decades of experience across infrastructure, cloud, and customer advisory roles have shaped his perspective on cost optimization, and what he’s learned after working with organizations that treat FinOps as a one-time project instead of a long-term practice. He explains why sustainable cost optimization starts with governance built on people, processes, and technology, how visibility and cost allocation are foundational to any FinOps journey, and why organizations must invest in education and accountability to scale their efforts. The conversation explores how teams can evolve from reactive cost-cutting to proactive cost management, the role of native cloud tooling in identifying and operationalizing savings, and why celebrating wins is critical to driving cultural adoption. Loic also dives into the growing impact of AI on cloud spend, highlighting the importance of early governance, thoughtful model selection, and efficiency-focused experimentation, while emphasizing that effective FinOps not only reduces cost but also supports broader sustainability goals.
