Executive Architecture Summary

Cloud waste is ubiquitous in scaling enterprises: idle non-production environments, unoptimized EBS volumes, over-provisioned Kubernetes nodes, and non-tiered object storage. i26 conducts rapid, forensic FinOps audits and implements automated IaC policies that reduce monthly cloud expenditure by 45–60% without compromising reliability.

The Enterprise Challenge & Cost Liabilities

Rapid engineering expansion inevitably leads to unmonitored cloud sprawl: - Static node groups running 24/7 at 15–20% average CPU/memory utilization. - Thousands of gigabytes of cold logs and snapshots accumulating on premium gp3/io2 volumes without lifecycle expiration policies. - Lack of cost allocation tagging, making it impossible to attribute cloud spend to specific business units or products.

The i26 Engineering Solution & Blueprint

- Deploy **Karpenter** on EKS/GKE to replace rigid cluster autoscalers with just-in-time, heterogenous Spot and On-Demand instance provisioning. - Implement automated non-production cluster scheduling (scale down to zero outside engineering hours). - Migrate S3/GCS buckets to Intelligent-Tiering and automated cold glacier archival. - Establish OpenCost and Grafana FinOps dashboards for unit-metric accountability (cost per transaction, cost per active user).
