Cloud and AI Cost Optimisation

Cloud and AI bills you can explain, with savings that hold after the first review.

Why It Matters

Cloud bills often grow faster than usage, as teams share accounts and tags go missing.

Nobody can say which service caused the rise. AI adds a line that is harder to see, because agent workflows can call a large model at every step.

What We Do

  • Each line of spend has an owner and a trend against the baseline, so you can see which team or feature changed it.

  • Model calls and accelerators grouped by feature, with caching and smaller models lowering the bill without lowering the quality bar.

  • Workloads matched to real demand and commitments bought against stable use, with the risk shown before you commit.

  • Work sized and scheduled with its power use in view, and reports that give your sustainability team the figures it needs.

What Changes for You

  1. Each line of spend has an owner and a trend, so you can see which team or feature changed it.

  2. Waste is removed, workloads fit their demand and commitments match use, with savings measured against a recorded baseline.

  3. Teams get targets, reports and a routine review, so the saving survives after the first clean-up.

What We Run and Watch

We look at what you spend and what drives it. The scope names each account and each team that owns a line.

  • Cloud Spend

    Accounts, services and data transfer are measured by team and workload. Shared costs are split by a rule your finance team accepts.

  • Workloads

    Each workload is compared with its demand. Idle capacity, oversized machines and unused storage are listed with a fix.

  • AI Usage

    Usage is grouped by feature, not only by account. Caching and smaller models are tested against a quality bar.

  • Commitments

    Reserved capacity and savings plans are matched to stable use. We show the risk before you commit.

Onboarding

The work starts with the bill and ends with a change your team owns. Each stage produces evidence you can check.

  1. Collect the Data

    We connect billing exports, tags and usage records. You give us access to each account and name the owner of each tag.

  2. Set the Baseline

    We record current spend, usage and performance for each workload. You confirm the baseline before we count any saving.

  3. Find the Waste

    We list idle capacity, oversized machines, unused storage and model calls that add nothing. You decide which items to fix first.

  4. Make the Change

    We resize, remove, cache or route one item at a time. You approve each change and its route back before it is applied.

  5. Review and Repeat

    We compare the new bill with the baseline and report what worked. You agree the next round from that result.

Reporting

You see the spend, the change and the evidence behind both. Reports use the same figures your finance team already keeps.

  • A Monthly Report

    Spend by team, service and AI feature, with the change against the baseline. Every line has an owner.

  • A Forecast

    Expected spend for the coming months, with the assumptions written down. You see the effect of each planned change.

  • A Board Summary

    Leaders see the trend, the savings and the choices ahead. Detailed tables follow in an appendix.

Platforms and Technologies

We work inside Amazon Web Services (AWS), where most of the spend is visible. Kubernetes shows how workloads use their capacity. OpenTelemetry, Prometheus and Grafana supply the usage and performance data behind each change.

How We Run the Estate

Insights

Questions

What finance and technology leaders ask before they start.

How much can you save?

It depends on the waste we find and how fast your team can change. We estimate each item first and report the result against the baseline.

When will we see a lower bill?

The first changes show in the next billing cycle. Larger commitments take longer and need your finance team's approval.

What does the work cost?

The scope, the accounts and your tagging set the effort. You receive a proposal with the stages and the effort before work starts.

Do we need to change how teams work?

Teams get a monthly figure and a target for the lines they own. A short review keeps the saving from drifting back.

Does this cover AI costs as well as cloud bills?

Yes. We measure model calls, tokens and accelerator use by feature. Caching and smaller models are tested before they go live.
