62% lower AWS spend. Same performance.

An infrastructure audit removed unused capacity and aligned resources with actual usage, reducing the monthly AWS bill without downtime.

01 Context

An AWS bill without a map.

The client ran its workloads on AWS across multiple accounts, and the environment had grown organically over time.

No one had a clear picture of what was running, what was still needed, and what was simply burning money. Idle instances, unattached storage and oversized compute were consuming budget without matching actual demand.

02 Challenge

An AWS estate without a clear inventory.

The client's Cloud environment had grown organically over time. No one had a clear picture of what was running, what was needed, and what was burning money.

Before

Idle instances, unattached storage and oversized compute were consuming budget.

After our work

Resources were right-sized to usage, with monitoring to prevent future drift.

The key decision: Optimize usage before adding capacity.

03 Approach

Audit, right-size and monitor infrastructure.

Optimize usage before adding capacity. The audit identified idle instances, unattached storage and oversized compute, allowing the work to focus on resources that were consuming budget without matching actual demand.

  1. Inventory everything

    A comprehensive audit of all cloud resources across accounts, so every cost had an owner and a purpose.

  2. Find the waste

    Identified idle instances, unattached storage, oversized compute and redundant services.

  3. Right-size to real usage

    Matched infrastructure to actual usage patterns instead of peak guesses, with zero downtime or performance impact.

  4. Keep it that way

    Implemented monitoring to catch drift early, so savings did not erode after the engagement.

04 How it works

From inventory to monitored, right-sized infrastructure.

The work moved in one direction: see everything, remove what is not needed, size what remains to demand, and watch for drift.

Conceptual resource audit: idle compute, unattached storage and oversized resources are reviewed, right-sized and monitored.

05 Results

Lower running costs. No service disruption.

62%

Monthly cost reduction

Reduction in monthly cloud costs after the infrastructure audit.

Operational outcome

Zero downtime or performance impact

The case reports no downtime or performance impact during the change.

Operational outcome

Ongoing drift monitoring post-engagement

Monitoring continued after the engagement to prevent infrastructure drift.

“We had no idea how much money we were leaving on the table. Software Sushi came in, audited everything, and within weeks we saw a 62% drop in our monthly AWS bill.”

06 What the client got

What we delivered.

  • Resource inventoryA complete view of what was running across accounts.
  • Waste findingsIdle instances, unattached storage, oversized compute and redundant services, ready to act on.
  • Right-sized infrastructureResources aligned with actual usage, with no downtime.
  • Drift monitoringOngoing monitoring that continued after the engagement.

08 Takeaway

You cannot optimize what you cannot see.

The largest savings came from visibility, not from new technology. An inventory first, then right-sizing, then monitoring keeps a cloud bill tied to the work it actually supports.
