AWS Cost Attribution
Every AWS CUR line item traced to its owner
FinOpsVyn reads your Cost and Usage Report from S3 and maps each line item — EC2, RDS, NAT Gateway, EBS, data transfer — to the team that owns it. Tags resolve first. Terraform state and GitHub CODEOWNERS fill the gaps. Amortized Reserved Instance costs are distributed across the teams consuming the capacity. FinOpsVyn does not modify your AWS infrastructure.
What FinOpsVyn does for AWS
Attribution that survives inconsistent tagging
Most AWS environments with $1M+ spend have partial tag coverage — infrastructure deployed before tag policies existed, resources created by tools that don't propagate tags, and shared services that span multiple team budgets. FinOpsVyn fills those gaps using Terraform resource metadata and GitHub CODEOWNERS — so attribution coverage reaches 90%+ even before you fix a single missing tag.
Three-layer tag resolution
FinOpsVyn reads your existing cost allocation tags from CUR first. For resources with missing or stale tags, Terraform state maps the resource ARN to the module and workspace that declared it. GitHub CODEOWNERS resolves which team owns that infrastructure path. The cascade handles tag propagation gaps across EC2, RDS, ECS, Lambda, and all other AWS service types in the CUR.
CUR line-item attribution with amortized cost
We ingest your Cost and Usage Report directly from S3 and process every line item: EC2, RDS, S3, ECS, Lambda, NAT Gateway, data transfer, and support charges. Amortized Reserved Instance fees and Savings Plan commitments are distributed across the teams consuming the capacity in that billing period — not pooled as an unallocated savings line item. You see true allocated cost per team, not blended on-demand rates.
Cost anomaly alerts scoped to the team that owns the resource
When EC2 spend for the Data team crosses a 20% day-over-day threshold against the 14-day rolling baseline, the alert goes to the Data team's Slack channel — not a generic #cloud-costs channel that nobody watches. The alert surfaces the specific resource, yesterday's cost versus baseline, and which IAM principal last modified it. Budget alert thresholds are configurable per team in the FinOpsVyn dashboard.
Weekly squad cost digest in Slack
Every Tuesday morning, each team lead receives their squad's cost digest: top-5 spend drivers, week-over-week delta, Savings Plan and Reserved Instance coverage percentage for their workloads, and any unattributed spend that needs a tag review. Links drill into the FinOpsVyn dashboard for per-resource detail.
Setup in 4 steps
From CUR to team attribution in under an hour
-
01
Connect your AWS account
Create a read-only IAM role with billing read access and paste the ARN into FinOpsVyn. We verify access and begin pulling your Cost and Usage Report from S3.
-
02
Link your Terraform state
Connect your remote Terraform state (S3 bucket or Terraform Cloud workspace). FinOpsVyn reads resource metadata — who declared each resource and in which module.
-
03
Connect GitHub
Install the FinOpsVyn GitHub App (read-only). We read CODEOWNERS files to map infrastructure repo paths to team ownership. No write access required.
-
04
Attribution goes live
FinOpsVyn processes your CUR history and assigns owners. The attribution dashboard populates. Slack alerts activate for the teams you choose to notify.
From CUR to team attribution in under an hour
Connect your S3 CUR bucket with a read-only IAM role. Attribution goes live within 24 hours. No agents. No code changes. No write permissions requested.
