Case study 2 · 2025
Cloud platform modernization and cost optimization for a European organization - a very significant reduction in operating costs through rightsizing, resource optimization and architecture review, with Terraform IaC and process automation for lasting efficiency.
Operating cost reduction
Architecture reviewed
The challenge
A European organization's cloud operating costs had grown faster than the value they returned. Spend lacked clear ownership, rightsizing and financial governance, and leadership wanted a controlled, sustainable reduction rather than a one-off cut.
The goal was a real program, not another report: lower operating costs significantly while keeping reliability intact, and modernize the platform along the way.
Our approach
We defined and executed initiatives for operational, financial and technological optimization. First came visibility into where the money actually went, then a prioritized set of optimizations across rightsizing, idle and wasted resources, and architecture.
Rightsizing and resource optimization ran alongside an architecture review that removed structural cost drivers. We implemented Infrastructure as Code in Terraform and automated processes to raise consistency and operational efficiency.
FinOps cost-control practices, cost allocation and guardrails were put in place so the savings would hold, with continuous modernization and ongoing support for the improvements the client asked for.
The outcome
A very significant reduction in cloud operating costs, achieved through rightsizing, resource optimization and architecture review, without compromising reliability.
Terraform IaC and process automation made the platform more consistent and efficient, and continuous modernization kept it current.
Beyond the immediate saving, the organization gained FinOps cost-control practices that keep spend transparent and under control as it grows.
