This is an example of what Numinexus delivers after analysing an AWS account. All data is representative. Your report will be specific to your infrastructure.
Account: acme-production
Region: us-east-1
Analysis period: Feb 6 – Mar 8, 2026
Monthly spend: $12,400
Total savings found: $2,340/month (18.9%)
Recommendations: 5Service Monthly Spend % of Total
─────────────────────────────────────────────────
EC2 (instances) $4,200 33.9%
RDS $3,100 25.0%
S3 $1,800 14.5%
NAT Gateway $1,400 11.3%
EBS Volumes $900 7.3%
Lambda $420 3.4%
CloudFront $310 2.5%
Other $270 2.2%Recommendation #1 — High confidence
Downsize EC2 instance i-0a3b7f2e
Current: m5.xlarge (4 vCPU, 16 GB) — $312/month
Suggested: t3.medium (2 vCPU, 4 GB) — $60/month
30-day avg CPU: 2.1%
30-day avg memory: 18%
Peak CPU (p99): 12%
Network I/O: Low
Estimated saving: $252/month
Risk: Low — no CPU or memory pressure in 30 days
Action:
Stop instance → change instance type to t3.medium → start.
Consider using a change window during off-peak hours.
If burstable workload is a concern, t3.large ($120/month) is
a conservative middle option.Recommendation #2 — High confidence
Route S3 traffic through VPC endpoint to reduce NAT Gateway costs
NAT Gateway data processing: 1.8 TB/month
S3-bound traffic estimate: 1.2 TB/month (67%)
Current NAT cost for S3 traffic: $54/month (data processing)
+ $840/month (data transfer)
VPC endpoint cost: $0 (gateway endpoint, free)
Estimated saving: $894/month
Risk: Low — S3 gateway endpoints have no bandwidth limits
Action:
Create an S3 gateway endpoint in vpc-0f4a. Update route tables
for private subnets. S3 traffic will route through the endpoint
instead of the NAT gateway.Recommendation #3 — High confidence
Delete 6 unattached EBS volumes
Volumes: vol-0a1b, vol-0c2d, vol-0e3f, vol-0g4h, vol-0i5j, vol-0k6l
Types: 4x gp3 (500 GB each), 2x io1 (200 GB each)
Attached: None — detached for 45+ days
Snapshots: Recent snapshots exist for 4 of 6 volumes
Estimated saving: $312/month
Risk: Low — verify no active references before deleting
Action:
Confirm volumes are not referenced by any AMI or launch template.
Delete via console or CLI:
aws ec2 delete-volume --volume-id vol-0a1bRecommendation #4 — Medium confidence
Investigate idle RDS instance numinexus-staging-db
Instance class: db.r5.large
Monthly cost: $438/month
Connections (avg): 0.3/hour over 21 days
CPU (avg): 0.4%
Storage: 200 GB gp3
Estimated saving: $438/month (if decommissioned)
$290/month (if downsized to db.t3.medium)
Risk: Medium — confirm staging environment is not in use
Action:
Check with your team whether this staging database is still needed.
If active but underused, downsize to db.t3.medium.
If decommissioned, take a final snapshot and delete.Recommendation #5 — Medium confidence
Move infrequently accessed S3 objects to S3 Intelligent-Tiering
Bucket: acme-assets-prod
Total size: 4.2 TB
Objects accessed <1x in 90 days: 3.1 TB (74%)
Current class: S3 Standard
Estimated saving: $444/month
Risk: Low — Intelligent-Tiering has no retrieval fees
Action:
Create an S3 Lifecycle rule on acme-assets-prod to transition
objects to Intelligent-Tiering after 30 days. New uploads will
remain in Standard until the rule applies.Total estimated monthly savings: $2,340/month
Annualised savings: $28,080/year
Percentage of current spend: 18.9%
High confidence recommendations: 3 ($1,458/month)
Medium confidence recommendations: 2 ($882/month)
