Optimizing AWS Costs Through Intelligent Cloud Management
We knew we had a visibility issue, but Centizen made it measurable and actionable. Their team didn’t just implement tools—they helped us make smarter cloud decisions every month.

A Leading Retail Group
A fast-scaling retail enterprise, the client had grown through multiple acquisitions, resulting in an increasingly complex AWS footprint. With inconsistent tagging, siloed environments, and a lack of spend oversight, they needed a structured approach to regain visibility and drive cost efficiency across their cloud infrastructure.
The Challenge
A fragmented AWS setup with unclear resource ownership and unexpected cost spikes made cloud budgets hard to manage and justify to leadership.
The Solution
Centizen formed a dedicated cloud cost management team, standardized tagging practices, and automated cost reporting and alerts to bring real-time visibility and control.
The Outcome
Within 3 months, the client achieved 30% cost savings, full visibility into AWS spend by team and service, and automated governance that continues to evolve.
