Room For Improvement

CAST AI needs improvements in documentation, interface, customization, reporting, cost insights, automation, governance, and cloud integration for Kubernetes.
Flexera Cloud Cost Management needs improved usability, integrations, automation, UI/UX, and enriched insights for an enhanced user experience.
There are many pros here, including easy onboarding, simple deployment, and excellent Kubernetes visibility, strong spot instance automation, and automated right-sizing.
Sr.Devops engineer at Scaler
More detailed documentation and deeper visibility into certain optimization decisions would also be helpful.
DevOps Engineer at Veefin
To improve CAST AI, I would like to see more granular reporting, deeper cost allocation insights, and additional customization options for optimization policies.

Flexera Cloud Cost Management can be improved by developing a normal chat interface or application where non-technical users do not have to navigate through Flexera API application or website.

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.
Senior Cloud Engineer at a energy/utilities company with 1,001-5,000 employees
Specifically, I would want purchase orders created from an on-premises licensing perspective to be replicated or pulled through from a SaaS visibility view so that licensing tracking happens seamlessly.

A particular strong differentiator regarding Flexera Cloud Cost Management is the ITAM and FinOps integration you have within the same solution, which is really rare in this market.

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.
