What is FinOps and how do dedicated FinOps tools differ from AWS Cost Explorer?

FinOps (Financial Operations) is a practice for managing cloud costs with accountability across engineering, finance, and product teams. Dedicated FinOps tools like Apptio Cloudability and CloudHealth add showback (allocating costs to teams), chargeback (billing internal teams), unit economics (cost per customer/transaction), anomaly detection, and optimization recommendations beyond Cost Explorer's visualization. For enterprises with multiple teams consuming cloud resources, FinOps platforms provide the governance layer Cost Explorer lacks.

What is Infracost and how does it prevent cloud cost surprises?

Infracost is an open-source CLI and CI/CD integration that parses Terraform plans and estimates the monthly cost impact of infrastructure changes before they're applied. When a developer proposes adding an RDS instance or increasing an EC2 type in a pull request, Infracost comments the estimated cost delta automatically. This shifts cost visibility left into the development workflow, preventing expensive infrastructure mistakes from reaching production unnoticed.

When should I use CAST AI instead of AWS Cost Explorer for Kubernetes cost optimization?

CAST AI specializes in automated Kubernetes cost optimization, right-sizing pod resource requests, automatically selecting optimal instance types, replacing On-Demand nodes with Spot instances, and bin-packing workloads to reduce wasted cluster capacity. AWS Cost Explorer provides general rightsizing recommendations but doesn't automate Kubernetes-specific optimizations. For teams spending significantly on EKS with variable workloads, CAST AI typically reduces Kubernetes infrastructure costs by 50-70% through automation.
