Featured Reviews

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.
Srivathsanr R. - PeerSpot reviewer
Head Of Business Finance at Zensar Technologies
Gained clearer financial governance and have improved cloud cost visibility and forecasting
I do not feel that anything needs to be changed. Umbrella is solving the purpose and is on point. The UI is intuitive and user-friendly. The learning curve is very easy. The features provided are on point. There is no downtime or challenges, and it is easy to learn and easy to use. In total, I do not feel that improvement is needed as per our organizational use case. Maybe for other organizations, they might have some suggestions, but for our organization specifically, I do not feel that they are lacking somewhere. It is already providing us the best thing. Almost everything is working as we expect. Small things we do not always point out. I feel that it works well and we do not have such problems with them specifically.
