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.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The TBM model and the out-of-the-box reporting are the most valuable features of Apptio One."
"Its most significant value lies in its ease of use which extends to both configuration and the subsequent deployment of additional components."
"In short, it helps finance, business, and IT people speak in a common language."
"In terms of cost savings, we have currently reduced our costs by 30 to 40%, and it saves time while managing infrastructure because it continuously monitors and provides the nodes to the application, so we don't need to do anything ourselves."
"Since using CAST AI, we have achieved approximately 30 to 40 percent reduction in our Kubernetes infrastructure cost."
"In the last Q2 result, because of using CAST AI, we have reduced our manpower, money, and cost by 20 to 30%, which indicates substantial funding reduction."
"Overall, CAST AI has been a valuable addition to our Kubernetes platform operations."
"CAST AI's machine learning algorithms that listen to the data generated by the cluster in order to optimize the workloads are among the best features offered."
"CAST AI positively impacted our organization by leading the migration of a very high number of pre-production environments from VMs to Kubernetes."
"Since adopting CAST AI, we achieved approximately 30-40% reduction in Kubernetes infrastructure costs."
"CAST AI monitors the workloads in the cluster and optimizes the number of nodes needed, their CPU and their memory so that we pay as little as possible."
 

Cons

"Encouraging or providing more out-of-the-box solutions that cater to a wider audience could enhance the overall effectiveness of the application."
"The solution's reporting layer, advanced conditional formatting, and reporting features could be improved."
"However, sometimes with the number of users using the system, there might be a lag in system performance."
"CAST AI can be improved in that automation policies require careful tuning."
"Perhaps improving the documentation a little would allow it to reach that rating, which has benefited me regarding that specific focus."
"CAST AI could be improved by adding some AI agent capabilities."
"The limitations of CAST AI include reporting and customization options."
"The reason I did not give it a perfect score is that I would still prefer to see more advanced cost reporting and workload-level analytics."
"CAST AI can be improved by managing the role-based access control better."
"I would like to see CAST AI improved with deeper and more intelligent answers and solutions, along with additional optimization and customization options."
"To improve CAST AI, I would like to see more granular reporting, deeper cost allocation insights, and additional customization options for optimization policies."
