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.

Optimized cloud workloads and cut costs while highlighting needs for clearer predictive insights
CAST AI is a useful platform for automating Kubernetes infrastructure and reducing cloud costs. However, I see improvement needed in cost visibility and reporting. There is a dashboard, but it doesn't showcase predictive scaling. A predictive scaling feature could be added where I can see more transparency around automated infrastructure decisions, especially when nodes and workloads are being replaced. There is a predictive cost involved, and that should be readily seen by CAST AI's dashboard so I could make better infrastructure choices and auto-scale in a better way. I would position myself to focus on better cost reporting and smarter predictive scaling as an added feature which could be a selling point for CAST AI. Additionally, there is the team saving concept where there could be visibility for different teams. Regarding understanding CAST AI's use case, I attended AWS re:Invent, where they sent out a demo to use CAST AI and other resources. I downloaded the necessary features and undertook the course to understand most of CAST AI's features. Although there was a demo and educational materials, CAST AI's use case needs to be more user-friendly for new users to understand what CAST AI is, what it is truly useful for, and where it exactly stands. The engagement with new users was limited. I could watch videos and have understanding about Kubernetes and where I could use CAST AI, but what about a person who would not know about Kubernetes or any scaling features? If a new organization wants to know about CAST AI and its use cases, they might face feasibility issues in understanding CAST AI and its applications. If there is a handbook, playbook, or basic guide showing where CAST AI can work well for them, that would help a lot for new users of CAST AI. I have mentioned most of the improvements I identified.

Quotes from Members

Pros

"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."
"The TBM model and the out-of-the-box reporting are the most valuable features of Apptio One."
"Overall, CAST AI has been a valuable addition to our Kubernetes platform operations."
"Since adopting CAST AI, we achieved approximately 30-40% reduction in Kubernetes infrastructure costs."
"The combination of cost efficiency, automation, and scalability makes CAST AI valuable and more scalable."
"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."
"CAST AI positively impacted our organization by leading the migration of a very high number of pre-production environments from VMs to Kubernetes."
"Since using CAST AI, we have achieved approximately 30 to 40 percent reduction in our Kubernetes infrastructure cost."
"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."
"The customer support is the best one I have ever used."
 

Cons

"However, sometimes with the number of users using the system, there might be a lag in system performance."
"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."
"To improve CAST AI, I would like to see more granular reporting, deeper cost allocation insights, and additional customization options for optimization policies."
"I would like to see more granular reporting, deeper cost allocation insights, and additional customization options for optimization policies in CAST AI."
"Perhaps improving the documentation a little would allow it to reach that rating, which has benefited me regarding that specific focus."
"I believe the improvements needed for CAST AI that I haven't mentioned yet involve the installation part from the Helm chart, as it's not optimized at the moment."
"CAST AI could be improved by adding some AI agent capabilities."
"I would like to see CAST AI improved with deeper and more intelligent answers and solutions, along with additional optimization 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."
"The limitations of CAST AI include reporting and customization options."
