Kubecost Cloud Architecture Overview

Kubecost Cloud uses an agent to gather metrics and send them to an S3 bucket.

The agent requires two pods and an optional daemonSet:

1. Kubecost Agent Pod
   1. Cost-model: Provides cost allocation calculations and metrics, reads from and scraped by Prometheus server
2. Prometheus Server Pod
   1. Prometheus server: Short-term time-series data store (14 days or less)
   2. Thanos sidecar: Ships metrics to Kubecost Cloud S3 bucket every 3 hours
   3. ConfigMap-Reload: Updates prometheus when changes are made. Learn more here.
3. Network costs Daemonset
   1. (Optional) Used to allocate costs to the workload responsible for egress costs. Learn more here.
