Savings Plans & RI modeling
Compare Compute SP, EC2 Instance SP, Standard RIs and Convertible RIs against your past 90 days. See break-even, lock-in risk and unused-coverage exposure.
AWS cost optimization
Cut AWS spend 25–40%. With a single read-only IAM Role.
Savings Plans & RI modeling, EC2/EKS rightsizing, RDS optimization, S3 lifecycle gaps and NAT Gateway egress traps — all from a single IAM Role.
IAM Role
Read-only, no keys
CUR-based
Cost & Usage Report
All regions
Multi-account aware
AWS pricing is a 700-page PDF. Lumicost reads your Cost & Usage Report (CUR), joins it with CloudWatch metrics and Trusted Advisor signals, and produces ranked recommendations: Savings Plans coverage, EC2/EKS rightsizing, RDS class downgrades, S3 storage class moves, NAT Gateway alternatives. One IAM Role across all accounts via AWS Organizations.
How Lumicost delivers AWS cost optimization
EC2 & EKS rightsizing
Right-size by family generation, with Graviton (arm64) migration scoring. EKS pod-level allocation across managed node groups, Fargate and Karpenter.
RDS, Aurora & DynamoDB
Detect over-provisioned RDS classes, idle read replicas, oversized Aurora I/O Optimized clusters and DynamoDB on-demand vs provisioned arbitrage.
S3, EBS, EFS & data transfer
Spot S3 buckets without lifecycle policies, idle EBS volumes, oversized EFS, and the silent killer: cross-AZ + NAT Gateway egress.
Multi-account via AWS Organizations
Onboard at the management account; we automatically enumerate member accounts via the Organizations API and CUR.
Frequently asked questions
What permissions does Lumicost need on AWS?+
A single read-only IAM Role with ce:Get*, cur:Describe*, ec2:Describe*, eks:Describe*, rds:Describe* and s3:Get*/List* (no Object access). Full policy is published and reviewable.
Do I need the Cost & Usage Report enabled?+
Yes — it's the only billing source granular enough for accurate optimization. We provide a CloudFormation template that enables CUR and grants the necessary permissions.
Does it support AWS Organizations?+
Yes. Onboard at the management account; we discover and analyze all member accounts via a single role assumption.
How is this different from AWS Cost Explorer?+
Cost Explorer shows what you spent. Lumicost tells you exactly what to change, ranks it by USD impact, and ships a remediation plan (Terraform / PR-ready). Plus multi-cloud and Kubernetes-native.
