At RebelCon 2024, one of the most pragmatic and actionable discussions focused on how engineering and finance teams can work together to optimise cloud costs without slowing down delivery.
Cloud platforms have made scaling faster and easier, but they’ve also introduced real challenges around cost control. As businesses mature, cloud spend often balloons unnoticed — until it becomes a problem.
The Speaker:
Fernando Munoz, VP of Technology Consulting at Zartis
Key insights from the session included:
🔹 Right-sizing is non-negotiable:
Teams often over-provision infrastructure “just in case.” Regular audits to match resources to actual usage are essential for sustainable cloud operations.
🔹 Leverage provider incentives:
Most major cloud providers offer substantial discounts for reserved instances, committed use, and spot instances. Smart commitment planning can cut costs significantly over time.
🔹 FinOps is becoming a must-have discipline:
Cost optimisation is no longer an ad-hoc task. Mature teams are integrating FinOps practices early — bringing together engineering, product, and finance to make cloud spending transparent and predictable.
🔹 Tooling matters:
Monitoring tools, cloud cost dashboards, and automated alerts for spend anomalies are crucial. Visibility is the first step toward action.
As organisations aim for efficiency and resilience, cloud cost optimisation is moving from a “nice to have” to a strategic imperative — and developers have a direct role to play in this shift.
