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.

Gain visibility into Kubernetes clusters and optimize resource allocation based on historical data
I think they should focus more on Kubernetes features that allow on-the-fly resource allocation without the need to restart services. They should implement this in their autoscaler to make it more useful in scenarios that require immediate scaling up or down. They should also offer more options for visualizing graphs in different ways, such as tabular views.

Quotes from Members

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

Pros

"CAST AI has reduced approximately 40% of our AWS bills and AWS cloud bills, really impacting our organization positively and enabling us to use our cloud better."
"Since adopting CAST AI, we achieved approximately 30-40% reduction in Kubernetes infrastructure costs."
"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."
"The combination of cost efficiency, automation, and scalability makes CAST AI valuable and more scalable."
"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."
"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."
"The cluster and workload autoscaler gives us the ability to have control over all the workloads' resources instead of managing them one by one."
"PerfectScale made our Kubernetes optimization effortless; it found wasted resources, lowered our cloud costs, and improved performance almost instantly."
"Automated resource optimization using different policies based on the environment enabled the organization to achieve infrastructure cost savings."
 

Cons

"There are some stability issues with CAST AI, especially during fluctuating workloads, where I saw that it was predicting not precisely or accurately."
"Perhaps improving the documentation a little would allow it to reach that rating, which has benefited me regarding that specific focus."
"CAST AI can be improved in that automation policies require careful tuning."
"I would like to see more granular reporting, deeper cost allocation insights, and additional customization options for optimization policies in CAST AI."
"The limitations of CAST AI include reporting 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."
"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."
"I would like to see CAST AI improved with deeper and more intelligent answers and solutions, along with additional optimization and customization options."
"At the beginning, the support was not very impressive."
"I think they should focus more on Kubernetes features that allow on-the-fly resource allocation without the need to restart services."
"With their in-place optimisations, stateful set optimisation would be a great addition."
