Cloud Cost Optimisation (CCO): control and reduce your Cloud costs without compromising performance

CCO is a structured approach to analyzing, managing and reducing the costs associated with the use of Cloud services. It is based on principles derived from FinOps and Green IT, combining performance, governance and digital sobriety. In concrete terms, it helps to avoid wasting resources, detect unnecessary subscriptions, better size services and adjust budgets according to actual needs. IT Systèmes supports companies in this approach, transforming the Cloud into a sustainable economic lever rather than an uncontrolled cost center.

Cloud environments are characterized by their agility: a single click is all it takes to deploy a new machine or service. This ease of access often leads to over-consumption. In practice, the most frequent causes are oversized instances, the absence of an automatic shutdown policy, lack of visibility on cross-billing between teams, and the multiplication of SaaS subscriptions. Without centralized governance, these expenses silently accumulate. IT Systèmes' CCO approach makes it possible to introduce financial safeguards, usage policies and automatic alerts to keep these excesses under control over the long term.

FinOps is the global discipline of Cloud financial management. It encompasses the culture, governance and processes that enable teams to take responsibility for their Cloud costs. CCO is the operational component, focusing on analyzing, rationalizing and automating savings. FinOps structures, CCO executes. Together, they enable the company to combine profitability, agility and security. IT Systèmes puts these two dimensions in place to guarantee measurable and sustainable optimization.

The main levers identified concern:- resizing resources (rightsizing VMs and databases),- eliminating inactive environments,- pooling resources between teams,- rationalizing software licenses,- and negotiating long-term reservation plans.These actions often lead to savings of between 20% and 40% of annual costs. We also support our customers in setting up alerts and management tools to maintain these gains over time.

The benefits are financial, technical and strategic. From a financial point of view, the reduction in expenditure is immediate and measurable. On the technical side, optimization improves service performance and availability. From a strategic point of view, CCO provides visibility, facilitates budget planning and strengthens collaboration between IT and finance departments. Finally, this approach contributes to greater environmental responsibility by reducing unnecessary energy consumption.

The first results usually appear within 4 to 6 weeks of the initial audit. Rapid savings often involve the removal of inactive resources and the resizing of instances. Over a period of 3 to 6 months, gains become structural thanks to the implementation of FinOps governance and ongoing monitoring. IT Systèmes makes sure that this dynamic is anchored in the long term through regular dashboards and steering meetings.

We use the native tools of Cloud providers: Azure Cost Management, AWS Cost Explorer, GCP Billing Reports, combined with customized dashboards in Power BI or Grafana. We automate controls via PowerShell scripts, APIs and Power Automate connectors.

Yes, systematically. Financial optimization must never compromise security. We integrate RGPD, ISO 27001, NIS2 and DORA compliance checks into every recommendation. For example, deleting a resource can only be considered if it complies with data backup and confidentiality obligations. IT Systèmes ensures that each economy is compatible with the legal and contractual requirements of your sector.

Yes, Cloud Cost Optimization is also part of a Green IT approach. By reducing unused resources and superfluous activity cycles, companies can reduce their digital carbon footprint. We measure the energy gains associated with optimizations, and can integrate CSR indicators into your dashboards. This approach reconciles economic efficiency and ecological responsibility, an increasingly important issue for general and financial management.
