CAST AI vs Harness Cloud Cost Management

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.

Harness Cloud Cost Management is a web service for tracking and managing spending across AWS, Azure, and Google Cloud Platform. It provides cost allocation, budget alerts, spend forecasting, rightsizing guidance, and commitment management. The billing model is based on tracked cloud spend. The Free Plan costs nothing and includes community support. The paid Cloud Cost Management plan has pricing on request, with fees charged as percentages of tracked spend: Cloud Cost Insights is 1% of total tracked cloud spend; Commitment Orchestrator and Autostopping are 1.25% for specified spend; and Cluster Orchestrator is 2% of tracked Kubernetes cloud spend. Harness was founded in 2017 and is headquartered in San Francisco, California. The service is offered on the web and uses a freemium pricing model, so organizations can begin with the free tier before requesting paid pricing for broader cost-management capabilities.
