DeepakReddy - PeerSpot reviewer
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.

Automated governance has eliminated shadow spend and now provides clear multi-cloud accountability
Flexera Cloud Cost Management could improve by modernizing the user experience, as many users find the interface feels a bit dated compared to cloud-native competitors such as Vantage or CloudHealth. Another suggestion is to deepen the AI-driven auto-remediation; Flexera Cloud Cost Management is excellent at providing recommendations, but it still requires a manual click to approve or a custom script to execute an action. I suggest simplifying Flexera Cloud Cost Management SaaS platform because Flexera Cloud Cost Management's special sauce is software asset management. Integrating those on-prem licenses with cloud usage can still be complex to set up for a user.
