Sr.Devops engineer at Scaler

Automated cost controls have cut cloud waste and free our team to focus on new projects

CAST AI can be improved in that automation policies require careful tuning. Sometimes it can be confusing for non-technical people or managers who are not familiar with technical details. However, it is good for technical people who are already into DevOps or cloud engineering. Spot strategies may need adjustment for sensitive workloads. The reporting and UI part can be somewhat better. Technical support can also be improved. Documentation is somewhat unclear sometimes, but not everywhere. There are many pros here, including easy onboarding, simple deployment, and excellent Kubernetes visibility, strong spot instance automation, and automated right-sizing. These features are very good for our organization because they reduce a lot of cost and reduce a lot of manual effort. However, some things can be improved, such as automation policies that require careful tuning and may need somewhat more help. Spot strategies can be improved, and some UI and documentation can also be improved.

Director at Zensa Technologies

Managing complex onboarding has been challenging but automated cost optimization delivers strong savings

Zesty is a good solution; however, the learning curve can be complex for new users without a solid tech background, posing a challenge in training and the initial setup process. I would deduct one point for this aspect since everything else is fine. A specific example of where the learning curve caused issues is when we introduced Zesty to our new development team, which struggled to understand the platform while working on a project related to AI and ML. Our system architects explained how Zesty works, but I believe a more proactive approach to training and foundational data could help teams be more self-sufficient and less reliant on internal support.
