Are Your Cloud Costs Increasing Without Clear Explanation?
Context
This SaaS scale-up was experiencing strong growth in its business and cloud usage. Its product platform, test environments, and data services relied on an AWS infrastructure that had become strategic to support performance and delivery speed.
However, as the organization grew, the cloud bill also increased, without sufficient visibility to precisely understand where the spending was going, who was responsible for it, or which levers to activate first.
Challenge
The client faced several simultaneous challenges:
Continuously Rising Cloud Bill
Expenses increased month after month, with growing difficulty in identifying the real causes of drift.
Lack of Visibility by Team and Environment
Costs were poorly legible across production, non-production, product teams, and technical usage, making arbitration difficult.
Ad-hoc Optimizations, but No Sustainable Framework
Some actions had already been initiated, but without clear governance or recurring oversight. Savings were therefore neither structured nor sustainable.
Need to Align Finance, Product, and Engineering
The topic of cloud costs remained primarily handled by the technical side, without a true common language with management functions.
Solution
Leonys supported the client with a pragmatic FinOps approach, focused on rapid impact and sustainability.
1. Comprehensive Cloud Spend Diagnostic
Our teams conducted a detailed analysis of costs by service, environment, team, and usage to identify the main areas of inefficiency.
2. Identification and Activation of Quick Wins
The highest-value levers were prioritized: unused resources, oversized environments, unoptimized storage, snapshots, and unmanaged usage.
3. Structuring Simple FinOps Governance
Leonys implemented a lightweight but effective management framework, with clarified responsibilities, clear indicators, and regular rituals between the teams involved.
4. Recommendations on Cloud Commitments
A review of consumption models identified relevant opportunities around Savings Plans and Reserved Instances, to improve economic performance without compromising agility.
5. Implementation of Decision-Making Reporting
Clear dashboards were built to allow decision-makers to track costs, understand discrepancies, prioritize actions, and secure the budgetary trajectory.
Results
In just a few months, the client was able to transform its cloud cost management into a true steering lever.
22% Reduction in Cloud Costs in 4 Months
Savings achieved through a combination of technical and organizational actions, prioritized according to their impact.
100% of Critical Spending Attributed
Major cost items could be linked to identified teams, products, or environments.
Improved Budget Predictability
The client gained in anticipation capacity and reliability in its exchanges between financial and technical management.
Sustainable Governance
Beyond immediate savings, the implemented structure helped limit the return of cost overruns and establish a logic of continuous improvement.
What This Case Illustrates
With Leonys, FinOps is not limited to reducing a bill. It restores visibility, accountability, and methodology to cloud management, creating sustainable savings without slowing down teams.
