Cloud Infrastructure Cost Optimisation at Scale

The Cost Creep Problem

Cloud bills have a habit of growing faster than product usage. Teams spin up resources to test a feature, forget to tear them down, and three months later they're paying for idle infrastructure. Without visibility and governance, cloud costs can quietly become a significant drag on your margins.

Right-Sizing Your Resources

The most common source of wasted cloud spend is over-provisioned instances. Teams size servers for peak load and leave them running at 10% utilisation the rest of the time. Auto-scaling groups, spot instances, and serverless architectures are modern tools for matching resource consumption to actual demand.

Tagging and Cost Allocation

You can't optimise what you can't attribute. Implementing a rigorous resource tagging strategy — by team, product, environment, and customer — gives you the visibility to understand where money is going and make informed decisions about cost reduction.

FinOps as a Practice

The best cloud-native companies treat cloud cost management (often called FinOps) as an ongoing practice, not a one-time project. Regular cost reviews, automated alerts for anomalies, and engineering team accountability for their own infrastructure budgets are the hallmarks of a mature cloud operation. Spilneo helps clients build this operating model as part of our cloud infrastructure engagements.
