Predicting and budgeting cloud costs: how to keep control of every euro with FinOps
The cloud is flexible. The cloud is scalable. But if you're not careful, the cloud can also be unpredictably expensive. Anyone working in the cloud today is all too familiar with the tension between technological freedom and financial control. In the public cloud in particular, it's often a matter of finding ways to keep control of budgets that can spiral out of control. The traditional way of budgeting no longer works. So what does? FinOps offers an answer.
A recent Gartner report stated that 40% of the companies surveyed were considering slowing down their cloud adoption due to unpredictable rising cloud costs. These figures show how great the need is for more control and predictability in cloud consumption, without organizations having to question their strategy.
From investment budget to consumption budget
In a traditional IT environment, you work with capital expenditures (CAPEX): you purchase servers, storage, and licenses, and depreciate them over several years. In the cloud, everything revolves around operating expenditures (OPEX): you pay for what you use.
This may seem efficient, but it also poses a fundamental problem: your consumption can suddenly increase. An extra test environment here, a forgotten service there, a spike in data traffic due to a marketing campaign... and your budget goes off the rails.
In the public cloud, this can even happen outside of IT. Think of a developer who starts up an expensive service with a credit card but forgets to stop it. A month and a half later, an invoice for thousands of euros arrives, without anyone knowing who or what caused it.
Why you need FinOps
FinOps — a contraction of “financial” and “operations”— is an approach to controlling that unpredictability. It is not a tool that you install, but rather a collection of principles and processes that help your organization make cloud costs transparent, predictable, and controllable.
This means, among other things:
- Creating visibility: who consumes what, and why?
- Linking costs to teams or projects: via showback (visibility) or chargeback (invoicing)
- Discovering patterns in consumption: using historical data for forecasting
- Warning of deviations: with alerts, ceilings, and approval flows
- Encouraging collaboration between IT, finance, and business: cloud costs are not just an IT issue
Public cloud: freedom within limits
In a public cloud environment, self-service is often an advantage, but also a risk. Developers can create, scale up, or shut down resources themselves. Without supervision, however, these freedoms can lead to unpleasant surprises.
That is why it is essential to provide guardrails. Dashboards and alerts give you insight into the costs per team or project, and you can automatically generate warnings if there are any deviations. You can set limits for specific environments or roles and only allow certain actions (such as creating expensive resources) after explicit approval. This allows you to enjoy the speed and flexibility of the cloud without the risk of spiraling costs.
Private cloud: predictability and control
In a private cloud environment, such as AXI Cloud, the situation is different. Here, you typically build a stable environment with predictable workloads. The costs are also more stable and easier to plan. But that does not mean that FinOps does not play a role here. In fact, transparency and cost allocation are also crucial in private clouds. A customer who provides IT services for different departments or business units wants to know who is using what.
AXI, for example, offers solutions that allow customers to pass on costs to internal departments at the VM level. This can be done on the basis of an allocation key, whereby certain VMs are assigned to specific entities. In addition, overarching costs can be distributed proportionally. The result is greater insight into costs and a considerable degree of accountability.
Smart budgeting in a cloud environment
How do you approach cloud budgeting in concrete terms?
Here are some proven FinOps practices:
- Scenario planning: work with multiple scenarios (growth, innovation, worst-case) in your budgeting.
- Behavior-based forecasting: use historical data and recognizable patterns to estimate future consumption.
- Commitment planning: for predictable workloads, you can work with reserved instances or commitment-based models.
- Dashboards and reporting: provide real-time visibility of consumption to all relevant stakeholders.
- Work with cost ownership: give teams responsibility for their own cloud costs. This increases engagement and ensures conscious consumption.
Think like a CFO: what are the benefits?
An important aspect that is often overlooked in the cloud cost debate is: what are the benefits? An organization that opts for a cloud strategy does so not only to save costs, but also to innovate faster and become more agile.
In a cloud model, you only pay for what you need, when you need it. You don't have to make large IT investments that may only pay off later. This allows you to focus your budget more on things that deliver immediate value to your business, such as product development or innovation.
The concept of Net Present Value (NPV) explains why this is beneficial: a dollar that you can invest in growth today is usually worth more than a dollar that is tied up in IT equipment for years. By spreading IT expenditure across OPEX, more capital remains available to gain an edge over your competitors.
In other words, FinOps is not just about saving money. It's about investing wisely.
Want to control your cloud costs? Start here.
Keeping cloud budgets under control requires more than a spreadsheet and an estimate. It requires a different mindset.
FinOps offers the processes and culture to make that shift, both in public and private clouds. Whether you opt for predictability and control (private) or speed and scalability (public), it's all about finding the right balance between freedom and responsibility.
Set up your processes, work with clear agreements, and give people the right insights. Then the cloud will become a strategic tool rather than a cost item.
