KUBECOST-OPENCOST

Kubecost OpenCost Kubernetes cost allocation CNCF.

Définition

Kubecost / OpenCost concepts : (1) Cost Allocation : repartit couts cloud (compute EC2 + storage EBS + networking + load balancers) en pods Kubernetes via resource requests (CPU + memory + GPU + storage requested per pod), labels-based grouping (namespace, deployment, label app=, etc.). (2) Idle Costs : identifie unused capacity (cluster overprovisioning, idle pods, idle nodes), pourcentage waste reporting. (3) Optimization Recommendations : rightsizing pods (request vs usage gap), Spot instances + Reserved Instances + Savings Plans recommendations. (4) Multi-cluster + Multi-cloud : federation costs across multiple clusters EKS + AKS + GKE + on-prem. (5) Integrations : Prometheus (metrics source), Grafana (dashboards), Slack/Teams alerts. Pricing Kubecost commercial : free Open Source (Helm install kubecost/cost-analyzer chart), Free Tier limited 10 nodes, Business + Enterprise paid tiers $250/cluster/month+ multi-cluster federation + advanced features. OpenCost CNCF Sandbox 2022 : standalone OSS Apache 2.0, Helm chart kubecost/opencost, FOCUS spec adapter, ~50000+ installs production worldwide.
