Kubernetes GPU clusters often face inefficiencies with a few GPUs working at full capacity while others remain idle, leading to a mismatch between expenditure and value derived from GPU resources. This challenge is exacerbated by the complex and manual configurations required for GPU sharing and management, especially as AI workloads grow. Dynamic Resource Allocation (DRA) changes this landscape by shifting GPU management from static configurations to intent-based allocations, allowing workloads to specify resource needs through resource claims, thus decoupling workload requirements from infrastructure specifics. Cast AI enhances this process by automating the provisioning and scaling of GPU resources to match demand, optimizing costs through intelligent instance selection and spot capacity utilization, and ensuring seamless operation without manual intervention. This approach not only improves efficiency by aligning infrastructure with workload intent but also reduces GPU idle time, ultimately allowing teams to focus more on developing models and applications rather than managing infrastructure. DRA support is currently available for GKE and EKS on Kubernetes 1.34 and above, with AKS support anticipated soon.

OMNI Compute for AI is a platform designed to optimize AI workloads across multiple regions and cloud providers by managing scarce GPU and compute resources within a Kubernetes cluster. It enables AI teams to deploy workloads without needing to refactor applications or incur additional operational overhead, offering seamless access to GPU capacity and allowing workloads to be placed where capacity is available, regardless of location. With features like GPU sharing, dynamic resource allocation, and intelligent scaling, OMNI Compute maximizes GPU utilization by adapting to real-time demands while maintaining performance and isolation. The platform also provides real-time tracking of GPU usage and cost attribution to help organizations optimize their resources. Testimonials from companies like Akamai, Yotpo, and Bede Gaming highlight significant cloud savings and increased productivity achieved through the use of OMNI Compute, as it automates and optimizes resource allocation with minimal human intervention.

Cast AI enhances the capabilities of Karpenter, an open-source Kubernetes autoscaler, by adding enterprise-grade optimization that improves performance, reduces costs, and boosts stability. It integrates seamlessly with Karpenter to provide advanced features such as workload optimization, Spot instance adoption, continuous rightsizing, and real-time cost visibility without the need for extensive reconfiguration. Cast AI enables zero-downtime container live migration, smarter consolidation, and predictive Spot handling, thereby optimizing Kubernetes clusters efficiently. The tool is designed to work alongside Karpenter, automating actions like rightsizing and consolidation while maintaining user control over the level of automation applied. With simple onboarding, Cast AI allows for incremental adoption and demonstrates significant cost savings and operational efficiency, as evidenced by case studies from companies like Akamai, Yotpo, and Bede Gaming.
