CAST AI vs. Zesty at a glance

Automated Kubernetes cost management, monitoring, and container security for the three major clouds. 
  • The platform delivers average savings of 63% thanks to multiple automated optimization features like spot instance automation, bin packing, and autoscaling.
  • It requires little configuration effort to bring long-lasting results for your infrastructure – and cut your bills for good. 
Limited cloud cost optimization features for teams using Amazon EC2 Reserved Instances.  
  • Zesty’s automated prediction and management of EC2 commitments promise to reduce costs by up to 60% without human intervention.
  • However, it doesn’t solve the root cause of waste – so unoptimized infrastructure will still haunt you in the long term.

Cloud Cost Transparency, Control, and Saving $3M on Amazon EKS

“When you start talking about those numbers, leadership cares, finance cares, they start building it into their cost projections and estimates. Even 1 or 3% of a massive AWS bill is significant. So when you say numbers like 20% people are losing their minds. And our total possible savings take that 20% closer to 60 or 70%, which translates to $3-4 million per year.”
