CAST AI introduces scheduled rebalancing, a new feature that helps users protect their cloud savings from spot instance pricing changes. Spot instances can be cost-efficient but are subject to price hikes due to market supply and demand. The scheduled rebalancer allows users to set criteria for when more cost-effective spot instances become available, mitigating the negative effects of price hikes. This feature enables teams to create cloud cost optimization plans that cover different use cases and automatically execute them based on preferences. CAST AI clients save an average of 63% on their Kubernetes bills with this technology.
