The main use case for CAST AI is Kubernetes cost optimization and cluster auto-scaling and spot instance management.
We use CAST AI for our CPU utilization. It monitors all the CPU utilization, usage, storage, network and node utilization, and then it automatically removes waste. CAST AI has reduced our AWS bills through better utilization and reduced idle resources.
We use the cluster auto-scaler in CAST AI. Instead of manually scaling nodes, CAST AI automatically adds nodes or removes unused nodes. It chooses cheaper instance types whenever we need any node or instance and prevents over-provisioning. This saves a lot of our AWS bills and achieves AWS cost optimization. This saves both engineering effort and cloud costs.
The best features that CAST AI offers are the cluster auto-scaler and spot instance automation. Spot instance automation is one of the strongest capabilities of CAST AI because it automatically finds the cheapest spot instances and replaces any interrupted spot nodes. It balances reliability and savings, allowing many companies to achieve significant savings through this feature. It optimizes cost substantially.
Another feature of CAST AI is workload resizing and right-sizing. It automatically resizes the workloads or allocates the workloads according to application behavior, CPU limit, CPU request, and memory request. It analyzes all of these factors and automatically allocates the workload or the instance.
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.
I have been using CAST AI for around one year.
CAST AI is stable. It does not have any downtime or any other issue.
The scalability is working well. We have a lot of workloads and a lot of instances. Even with these, the scalability of CAST AI is good.
Customer support and technical support for CAST AI was responsive, knowledgeable about Kubernetes optimization, onboarding, and provided guidance on optimization policies.
I have evaluated many other options including KubeCost, PerfectScale, and ScaleOps. CAST AI stood out from all of those options. The automation capabilities to continuously optimize the cluster with minimal manual effort while maintaining application performance really stood out apart from all those other solutions.

I would give the implementation team a rating of nine.
CAST AI has reduced approximately 40% of our AWS bills and AWS cloud bills. It has really impacted positively in our organization and we are able to use our cloud better.
With that 40% savings, we were able to invest that money into other projects. Rather than wasting money, we were able to save that money and use it on another project, building another project or anything else with the help of that money. This is pretty good for us. The manual effort has also been reduced here. It is an automated system and completely automated, which is good for us.
Even though CAST AI is slightly higher in cost, we are able to optimize and have saved 40% of our cost. This is definitely a win-win situation. Thirty percent to 40% of our money has been saved in cost through CAST AI for our Kubernetes workloads and AWS cloud instances.
CAST AI provides 80% to 85% accuracy. Because it is an AI system, sometimes it can make mistakes, but providing 80% to 85% accuracy is a pretty good number for any normal tool. It is good.
If you want to use CAST AI, first understand your workload capability. Whether you are using Kubernetes, you should go for CAST AI if you are using Kubernetes at a higher scale. You cannot go with CAST AI if you have only one to ten users. If you have a minimum of 1,000 customers who are using your Kubernetes workloads, then CAST AI will definitely decrease your workloads and analyze your workloads to decrease your cost. It has all the automated features, including cluster auto-scaler and workload right-sizing. These features really help optimize the cost of cloud automatically rather than manually optimizing the cost of cloud. I give this product an overall rating of nine out of ten.

Our main use case for CAST AI is Kubernetes cost optimization, automated node provisioning, and improving cluster efficiency.
I can provide a specific example of how we use CAST AI for Kubernetes cost optimization and cluster efficiency. Before implementation, we were manually handling all of these tasks. After implementing CAST AI, we are able to see the cost of each pod and node, and based on the reports from CAST AI, we can determine how to optimize our costs.
In day-to-day operations, we use CAST AI to monitor all workloads running on our cluster and evaluate how our nodes and pods are performing. We can determine if we need to resize the nodes and pods or if we are spending too much money on pods, which can be optimized through CAST AI's platform.
CAST AI has positively impacted our organization because we are now able to control our Kubernetes costs, and the automated node provisioning continuously monitors our application usage to select which node to provision, ensuring the application has sufficient compute power and improving our cluster efficiency.
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. This is a fully automated process. Additionally, manual intervention has decreased significantly because this is a completely automated process.
The best features that CAST AI offers, in my experience, are automated scaling, intelligent node selection, cost recommendations, and workload right-sizing.
The biggest feature that has made a difference for our team is that the platform continuously analyzes our cluster's user-based pattern and makes practical optimization suggestions, which saves our team significant time while helping us control cloud expenses.
CAST AI also helps us reduce the manual effort involved in managing infrastructure while ensuring applications always have the resources they need, which is very valuable.
The limitations of CAST AI include reporting and customization options. I think they can improve in these areas, especially when some advanced settings require a learning curve, particularly for teams new to Kubernetes optimization. More detailed documentation and deeper visibility into certain optimization decisions would also be helpful.
