Cloud computing promised to eliminate fixed infrastructure costs and provide infinite agility. But for most CFOs and CTOs, the reality has become unpredictable AWS or Azure bills and a total lack of visibility into the real return on investment.
The real problem with the cloud is not the price of machines, but the speed at which money can be spent uncontrollably. In the traditional model, buying a server required approvals, budgets, and months of planning. In the cloud, an engineer can spin up an oversized Kubernetes cluster with a single line of code, multiplying costs in a matter of minutes.
This is where**FinOps (Financial Operations)**comes in: an operational and cultural discipline that aligns financial, business, and technology teams so that the cloud stops being an uncontrolled cost center and becomes an engine of efficient growth.
The Cloud Paradox: From Agility to Waste
According to estimates from analysts like Gartner,over 30% of total cloud spend is systematically wasted[2]. This is not due to poor service from providers, but to a lack of internal governance policies.
Engineering and Finance have historically spoken different languages:
-Engineeringprioritizes performance, deployment speed, and availability (uptime). Their approach is: “Make it work always, just in case.”
-**Financial Engineering (Finance)**prioritizes predictability, cash flow control, and justifying return on investment (ROI). Their approach is: “Why did the AWS bill go up 20% this month?”
FinOps does not seek to cut costs at all costs (which could slow down innovation or compromise product quality), but rather tomaximize the value of every euro invested. It is the conversation that allows the company to consciously decide whether it prefers to spend more to grow faster, or consolidate resources to improve margins.
The Reactive Approach
Spend is detected when the bill arrives at the end of the month.
Scapegoats are sought among development teams.
Emergency cuts are made that damage performance.
Total lack of visibility on which component generates the spend.
The FinOps Approach
Real-time anomaly monitoring and alerts.
Shared responsibility: engineers see the cost of their code.
Continuous optimization without compromising speed or resilience.
Costs allocated to business metrics (e.g., cost per active user).
The 3 phases of the FinOps cycle
FinOps implementation is not a one-time project, but a continuous cycle structured in three well-defined phases:
1. Inform (Visibility and Allocation)
It is impossible to optimize what is not measured. The first step is to achieve 100% visibility into cloud spend. This involves creating a strict resource tagging strategy to allocate costs to specific products, departments, or clients, allowing for clear unit economics calculations.
2. Optimize (Efficiency and Rates)
Once the spend is identified, inefficiencies are sought. This covers Rightsizing (adjusting machine sizes to actual usage), scheduling shutdowns for development environments unused at night, and strategic purchasing of compute reservations (Savings Plans or Reserved Instances) to aggressively reduce rates.
3. Operate (Culture and Automation)
The ultimate phase is integrating FinOps into day-to-day operations. It consists of defining shared financial KPIs, automating governance policies so inefficient resources are shut down automatically, and ensuring the development team assumes financial cost as another quality metric, just as relevant as security or latency.
Why the CFO and CTO must lead this together
FinOps is not an isolated technical role nor a software you buy and forget. It is ajoint operating model.
When the CTO and CFO collaborate under a FinOps framework, decision-making accelerates. Instead of arguing about “exceeded budgets,” they discuss “marginal efficiency.” If the cost of processing a transaction on your platform drops from €0.10 to €0.04 thanks to architectural optimization, the company gains direct margin to lower prices or reinvest in marketing.
“Every euro you save on cloud waste goes directly to your organization’s EBITDA and cash flow. Optimizing the cloud is not just a technical goal; it is a direct competitive advantage.”
How to start today with no risk?
For most companies, starting FinOps internally is difficult because it requires specialized profiles (FinOps Certified Practitioners) who understand both cloud accounting and infrastructure (Kubernetes, databases, networks).
AtNubyron, we solve this directly and in a results-oriented manner:
The service pays for itself from month one
We audit your cloud infrastructure at no cost to you. We identify the real and potential savings of your environment, and our implementation fee is based exclusively on a percentage of the actual savings generated.
This way, Nubyron requires no additional budget or CapEx: we pay ourselves with the capital we recover directly from your AWS or Azure bill.
