CAST AI is an Application Performance Automation (APA) platform for Kubernetes that automates cost optimization, autoscaling, workload rightsizing, GPU/LLM workload placement, spot instance selection, and security posture analysis. The platform works across AWS, GCP, Azure, Oracle Cloud, IBM Cloud, AliCloud and on-premises distributions (EKS, GKE, AKS, OpenShift, Rancher, kOps). Everything available in the console UI is also accessible via the REST API at api.cast.ai.
