Featured Reviews

Jerry J - PeerSpot reviewer
Consultant at IBM
Cost transparency has improved and finance and IT now share detailed TCO insights
I am mostly concerned about the development side. The development side is very user-friendly, so I would not say there are major factors that the product needs improvement in. However, sometimes with the number of users using the system, there might be a lag in system performance. There might be some slowness for the report to load. If a more significant number of users are consolidating on a single report and that single report has not been promoted to production yet, there is a possibility that it could take some time to load. That is the only challenge I have experienced as a developer.
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.
