Cost Optimization Tips for Cloud Infrastructure

Introduction

As more companies move workloads to the cloud, managing costs is becoming a strategic priority. In 2025, over 70% of organizations report cloud overspending by 20% or more (Flexera State of the Cloud Report). Yet, many IT teams are flying blind—without the visibility, tools, or policies needed to control ballooning bills.

Cloud infrastructure doesn’t have to be expensive. It just needs to be optimized. Whether you're a startup scaling fast or an enterprise managing hybrid environments, this guide breaks down real, quantitative cost-saving strategies— backed by industry data and actual use cases.

Understand Where the Money’s Going First

The first step toward cloud cost optimization is visibility. It’s surprising how many businesses still don’t know what they’re spending on cloud services day-to-day. According to Gartner, 45% of cloud resources go underutilized or completely unused, often because instances are provisioned but forgotten.

One mid-sized fintech company cut its AWS bill by 32% in under 90 days—just by identifying idle instances and downsizing over-provisioned VMs using a cloud cost intelligence tool like CloudHealth. The key takeaway: you can't optimize what you can't see.

Right-Sizing Resources Based on Actual Usage

A common issue is over-provisioning. Teams often spin up instances with far more CPU, memory, or storage than they need—just to be safe. But that buffer quickly adds up.

Cloud providers like AWS, Azure, and Google Cloud now offer built-in right sizing recommendations. When applied, companies have seen savings of up to 40% on EC2 costs alone, simply by switching from general-purpose to compute optimized instances or autoscaling based on real-time demand.
