In their own words
CAST AI
CAST AI is an Application Performance Automation platform for cloud-native operations and Kubernetes automation. It automates workload rightsizing, node scaling, GPU and Spot optimization, and issue remediation. Rightsizing adjusts CPU and memory requests, limits, and replicas in response to workload behavior. The platform says its engine can predict Spot interruptions up to 30 minutes ahead and migrate workloads before a slowdown. Agentic runbooks can address operational and security issues, with approval required for each change before it ships.
Teams can connect clusters in read-only mode without infrastructure changes. Listed environments include AWS, Google Cloud, Azure, Oracle Cloud, IBM Cloud, OpenShift, Rancher, VMware Tanzu, AliCloud, kOps, PostgreSQL, MySQL, and on-prem Kubernetes. Cost tools include allocation, spend forecasting, rightsizing guidance, and commitment management. CAST AI integrates with tools including Grafana, Terraform, Prometheus, Jira, and Pulumi. It is available on the web and as self-hosted software. Pricing is custom and available on request; a free trial is available.
Varcio Kubernetes Cost Management
Varcio Kubernetes Cost Management maps Kubernetes spending to namespaces, deployments, workloads, and teams for allocation and control. Its 14 detectors cover issues such as request-versus-usage drift, idle pods, spot candidates, bin-packing headroom, and orphaned volumes. Rightsizing recommendations use measured CPU and memory utilization. Clusters connect through Kubecost, OpenCost, the native Kubernetes API, or Varcio’s bundled in-cluster agent. The agent is available on Business and Enterprise plans, reads metrics-server data, sends metrics outbound, and has read-only access to pods, nodes, namespaces, and pod metrics. Write-back is optional, and requested changes require approval. Kubernetes costs appear alongside AWS, Azure, Google Cloud, and OCI spending, with 23 cross-cloud detectors. Findings and approvals can route to Slack or Microsoft Teams. The product lists forecasting, commitment optimization, budget alerts, and evidence export for controls across eight compliance frameworks. Explorer costs $49 a month; a 14-day trial is listed.
