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.

Optimized cloud costs and automated right‑sizing have reduced spend while reporting needs improvement
The best features Densify offers are actionable optimization recommendations, which tell you how to reduce costs while maintaining performance; the ML-powered predictive analytics feature, which considers historical patterns to provide recommendations; multi-cloud coverage for optimization across AWS, Azure, and GCP; and a solid balance between performance and cost. Out of those features, I find myself relying on actionable optimization recommendations and predictive analytics features the most because Densify goes one step beyond by providing recommendations considering historical patterns, especially for workloads that only spike during certain times of the month. Densify has positively impacted my organization by providing significant cost savings through right-sizing and eliminating inefficient resources, allowing faster decisions based on data, and reducing manual intervention for cloud operations, thus providing automation of basic cloud routines. I usually see a twenty-five to thirty percent cost saving in my customer's environment, and from a time-saving perspective, it has almost halved the time of the operations team.

Quotes from Members

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

Pros

"CAST AI positively impacted our organization by leading the migration of a very high number of pre-production environments from VMs to Kubernetes."
"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."
"The combination of cost efficiency, automation, and scalability makes CAST AI valuable and more scalable."
"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."
"The customer support is the best one I have ever used."
"Overall, CAST AI has been a valuable addition to our Kubernetes platform operations."
"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."
"Densify were deemed to be the best for us at the time and they still are, for now."
"The Control Console is an incredible way to give a quick view of current capacity utilization allowing technical people to drill down quickly and allowing business/management people to get a quick overview of the environment."
"Using the reports from Densify will provide us with the trusted advisor backing for our own purchase and provisioning decisions."
"I usually see a twenty-five to thirty percent cost saving in my customer's environment, and from a time-saving perspective, it has almost halved the time of the operations team."
"From my perspective, this product is really good, and we are not even using each and every feature."
"The Control Console provides a very easy to read dashboard of "too little/just right/too much" resources both for current data and on a historical or predictive basis."
"The tool will come back and tell us that we can operate with 1,000 minutes as an example, save 90% on the contractual rate and not run into any issues."
"I would say that the initial thing is that it provides us with a technological basis to expand capacity management beyond Excel."
 

Cons

"I would like to see more granular reporting, deeper cost allocation insights, and additional customization options for optimization policies in CAST AI."
"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."
"CAST AI can be improved in that automation policies require careful tuning."
"To improve CAST AI, I would like to see more granular reporting, deeper cost allocation insights, and additional customization options for optimization policies."
"Perhaps improving the documentation a little would allow it to reach that rating, which has benefited me regarding that specific focus."
"Normalization of CPU utilization is required. At present, the data is available based on entitlement level."
"In terms of integration, the tool has great data. However, it's not always meaningful because the true business attributes of how most Fortune 500 companies operate are not maintaining in one tool, they're in a school of many tools."
"A closer integration to the service management processes."
"Initially we talked about some custom reporting, wherein our customer expected certain reports on a few areas, like how the storage is allocated, how the network performance is doing, and how the network utilization is happening for a virtual machine."
"Some parts of the interface are rather complex and require a bit of time to navigate, but this has never stopped us as a Densify advisor is readily available to help with our "how to" queries."
"Densify can be improved in a couple of areas: the learning curve for new users, where it feels like an advanced optimization tool that needs time for full leverage; enhancements in reporting and filter options for more detailed custom reports; and improvements in UI performance since some users feel that the UI is a bit slow or outdated, especially with certain interfaces such as the Kubex Console or the Cloud Decks."
"Unfortunately the tools and mechanisms which really came to maturity in the cloud, and were not mainstream on-premise, are still not implemented."
"There are times when results are very slow when we search for servers."
 

Pricing and Cost Advice

"Densify has licensing setup so you can collect data without licensing. It gives you the ability to collect on everything, then choose later what you would like to license."
"Cost is always involved, but then I feel that this solution is better than other products that we have."
"There was some sticker shock, as this is not just another software product to spit out graphs."
"Setup cost is negligible, as it scales fairly well."
