CAST AI Reviews

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.

The setup was good and easy integration. It has all the steps and clear documentation. I would give this a rating of nine out of ten.

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.

My main use case was to migrate development and staging environments to Kubernetes using CAST AI, and with them, we created these environments. We moved them from virtual machines to Kubernetes clusters.

CAST AI helped with that migration by creating a Kubernetes cluster designed to automatically manage infrastructure components. This allowed us to boost the project I work on inside Zazmic. This allowed us to focus on application deployment rather than complex infrastructure provisioning. The team also gave direct feedback to us when we were implementing. They developed specific scripts to automate the creation. This enabled the team to easily spin up or tear down environments on demand as needed for testing and validations.

CAST AI positively impacted our organization by leading the migration of a very high number of pre-production environments from VMs to Kubernetes. We had these specific sandboxes for each developer, and there was a high volume of environments. This helped us make it easier to administer and manage each environment for each developer. It really gave us an opportunity to manage our systems better. Regarding cost and savings, CAST AI's optimization software helped us move away from a mess of machines in our environments to really make progress on that matter, to manage our costs better, and have a more maintained environment, and use our resources better.

CAST AI can be improved by managing the role-based access control better. I think it would be better for CAST AI to improve how access permissions are handled for developers. That would be a beneficial refinement on that matter. Managing node management better is important. We had a recurring issue with our nodes where they were becoming not ready and required manual deletion to be reclaimed by the cluster. Making this automation better would be great. The cost optimization is great, but improving the automation implementation of cost-saving measures, such as weekend scaling, would be something useful as well.

We began to work with CAST AI on April 2021.

CAST AI is stable.

The customer support is great. The customer support and the team effort to help us put the cluster up or maintain it is great. It is really useful.

Before choosing CAST AI, we were evaluating putting up the Kubernetes clusters by ourselves, but we chose CAST AI to help us on that matter first.

We had monthly savings of 2,500 to 3,000 from our bills on cloud.

My experience with pricing, setup cost, and licensing was that the proposal they shared with us included an ongoing monthly cost. There was a one-time setup cost as well, but all that we spent with CAST AI was okay because we have monthly savings that surpassed what we spent with the tool.

Automation and infrastructure optimization features helped my team by creating the cluster to manage infrastructure components. This allowed the booster project to focus on application deployment rather than complex infrastructure provisioning. These features made it easier for the administration of the creation of the cluster and administration of it. We did not have to spend so much time going through the cloud itself to provide this for us.

The best features CAST AI offers include automated infrastructure management, infrastructure optimization, and tooling for automation. These are things that stand out. The possibility to use solutions integrated with it is particularly helpful.

The migration to Kubernetes helped reduce cloud costs by enabling the use of preemptible instances and optimizing cluster infrastructure.

Regarding CAST AI's AI capabilities, I think its governance and security are well-managed. We did not have issues with how it is handled and how we give people access to the systems or to CAST AI itself.

CAST AI's capabilities are really accurate and reliable.

I would rate this product a 9 overall.

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.

We have been using CAST AI for six to eight months.

CAST AI is 100% stable.

CAST AI is 100% scalable. You don't have to do anything in terms of scaling because it is a SaaS platform that will scale automatically, no matter if you have 100 or thousands of Kubernetes clusters running. CAST AI can handle all the loads you have.

The customer support is very good. I have raised queries numerous times as a new user and found the customer support excellent. I would rate the customer support 10 out of 10.

We haven't used any different solutions prior to this.

The setup process is relatively straightforward. Integrating CAST AI with a Kubernetes cluster and cloud environments doesn't take very long, so the setup is very easy.

We have seen a return on investment, with money saved equating to approximately 30 to 40% ROI. I consider it a very good investment, and the overall ROI is approximately 20 to 30%.

In terms of pricing, I believe the pricing is reasonable because of the amount of savings and operational efficiency it delivers, making it easier to justify the investment. Organizations with larger Kubernetes footprints are likely to see the most value.

We haven't evaluated other options before choosing CAST AI.

CAST AI delivers strong value through automation and cost optimization, but there are still a few areas where usability and reporting could be improved. Overall, it has a positive impact on our infrastructure management.

Their governance is compliant with all frameworks, and in terms of security, I believe they are very secure.

Their accuracy is approximately 80 to 90%, and in terms of reliability, it is the same—approximately 80 to 90% reliable for the output it provides.

Teams struggling with Kubernetes costs, especially larger teams with multiple Kubernetes clusters or workloads, should consider using CAST AI. It offers a very good return on investment while saving both operational time and money. I would rate this review an 8 out of 10.

CAST AI serves as our primary solution for Kubernetes cost optimization and automated node management in our EKS cluster.

One example of how we use CAST AI for cost optimization and node management is in our production EKS environment where workload fluctuates throughout the day. Before CAST AI, we manually sized node groups and often provisioned over-provisioned resources. CAST AI automatically provisions the most cost-effective instances and continuously right-sizes the cluster based on workload demand. This significantly reduced unused capacity while maintaining application performance.

We use CAST AI daily to monitor cluster efficiency, optimize resource allocation, and reduce the operational effort required to manage Kubernetes infrastructure.

The best features CAST AI offers, in my experience, are automated Kubernetes cost optimization, intelligent auto-scaling, spot instance management, workload right-sizing recommendation, and cluster visibility.

CAST AI has proven to be stable and reliable in production environments.

CAST AI's scalability is very good; it scales effectively with cluster growth and increasing workload complexity.

Our experience with customer support has been positive. Response times are reasonable and the team is knowledgeable.

Before CAST AI, we relied mainly on Kubernetes auto-scaling and manual monitoring processes.

Before choosing CAST AI, we looked at AWS native optimization tools and a few Kubernetes cost optimization platforms before selecting CAST AI due to its automation capabilities.

I have seen a return on investment, and the ROI was visible within a few months through cloud cost reduction alone. Additionally, our team spends less time manually managing Kubernetes infrastructure.

My experience with pricing, setup cost, and licensing was that the setup process was straightforward, pricing was reasonable considering the cost savings achieved, and licensing was easy to understand.

Since adopting CAST AI, we achieved approximately 30-40% reduction in Kubernetes infrastructure costs. We also reduced manual cluster management activities significantly, especially around node scaling and capacity planning.

The best features CAST AI provides are automated Kubernetes cost optimization, intelligent auto-scaling, spot instance management, cluster visibility and analytics, and workload right-sizing recommendations.

Regarding the accuracy and reliability of CAST AI's AI capabilities, recommendations are generally accurate and reliable. We always validate major changes, but in most cases, the optimization suggestions are practical and effective.

My advice to others looking into using CAST AI is to start with a non-production cluster to understand the optimization recommendations, establish baseline cost metrics, and then granularly expand adoption across environments.

Overall, CAST AI has been a valuable addition to our Kubernetes platform operations. It helped us reduce cloud spending while simplifying cluster management, and I would recommend it to organizations looking to optimize Kubernetes cost at scale. I rated CAST AI as an eight out of ten.

CAST AI allows me to have test workloads that use spot-type machines.

The best features that CAST AI offers are its machine learning algorithms that listen to the data generated by the cluster in order to optimize the workloads.

With just a couple of clicks and a very high-level definition of what is needed, CAST AI starts gathering the data and executes the actions automatically while producing quite a lot of reports.

It is also interesting that the same tool works for different clouds.

CAST AI has positively impacted my organization through cost reduction.

On average, I think the savings are between 15 and 20%, and for certain workloads, those savings can be even higher.

Improving the documentation would help the platform reach a perfect rating.

I measured the cost reduction by tracking our AWS infra cost month over month after enabling CAST AI across our Kubernetes cluster. The biggest improvement came after we enabled automated node provisioning, workload resizing, and spot instance optimization. Within the first two to three months, we saw a consistent reduction in compute costs while maintaining the same application performance and availability. We also compared resource utilization before and after the deployment and found that the clusters were running much more efficiently with significantly less over-provisioned capacity.

The best features CAST AI offers, as per my experience, would be the automated Kubernetes cost optimization, intelligent auto-scaling, workload right-sizing recommendations, cluster visibility and analytics, and spot instance management.

Intelligent auto-scaling has helped my team by automatically adjusting cluster capacity based on real-time workload demand. Earlier, we had to manually plan for specific traffic spikes, which often resulted in over-provisioned resources during low-usage periods. With CAST AI, nodes are added or removed automatically as workloads change, helping us maintain application performance while reducing unnecessary cloud costs. It has also reduced the operational effort required to manage Kubernetes clusters on a daily basis.

I would appreciate seeing CAST AI improved with more granular reporting, deeper cost allocation insights, and additional customization options for optimization policies.

Overall, the platform is strong. The most needed improvements would be around reporting and advanced governance capabilities for large organizations.

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.
