CAST AI's Instant Rebalancing feature automates the process of optimizing Kubernetes cluster configurations for cost efficiency, reducing compute costs by 50% or more within minutes. The platform uses advanced algorithms to rightsize clusters and keep them in an optimized state without human effort. With recent updates, users can now partially rebalance their clusters, giving them more control over infrastructure management. Instant Rebalancing also enables teams to benefit from cost-efficient spot instances offered at discounted rates across various cloud providers.
