**Reviewed by:** Johannes G. | Expert Lead Cloud and DevOps, Enterprise (> 1000 emp.)

**Reviewed Date:** November 25, 2024

**What do you like best about Cast AI?**

It was very easy for us to switch from AWS EKS Karpenter to CastAI. There Terraform Modules enabled us to integrate it perfectly into our Infrastructure as Code workflows.

We already during the POC, were able to reduce the Instance Costs by arround 30%, so the product payed for itself. Because of that it was very easy to convince the management to buy the product.

Right now we are working together with cast ai to implement vertical and horezontal autoscaling for all our main workloads (Cast ai VPA+ keda HPA).

**What do you dislike about Cast AI?**

Permission Model needs to be extended. Currently there is no way to give permissions per cluster or namespace. That would be needed for shared responsibility.

**What problems is Cast AI solving and how is that benefiting you?**

It improves the Cluster Node Scaling and Spot selection. This reduces Instance costs already by arround 30% for us.

We are working on implementing Autoscaling for all our major workloads, by combining cast ai's vertical pod autoscaling and Keda for horezontal autoscaling on application metrics.

  ### 38. Cast.AI: Innovative savings automation meets outstanding support

**Rating:** 4.5/5.0 stars

**Reviewed by:** Dario L. | Devops SRE, Mid-Market (51-1000 emp.)

**Reviewed Date:** November 26, 2024

**What do you like best about Cast AI?**

Cast.AI's cloud cost automation offers a robust solution for resource optimization through its innovative technology, significantly alleviating the burden on DevOps teams. As it integrates seamlessly into our Kubernetes clusters, it has become a critical component of our infrastructure. Without the solid support from Cast.AI, the integration process could have been risky and complex.
What truly sets Cast.AI apart is how it simplifies onboarding and ensures that users can effectively utilize all features. The support team is always prompt and effective, providing the necessary guidance to navigate the complexities of the tool. This level of assistance instills confidence in both the platform and the dedicated professionals behind it.

**What do you dislike about Cast AI?**

I have no significant complaints about Cast.AI; any issues encountered during our integration journey have been promptly resolved by the support team or even directly by the developers.

**What problems is Cast AI solving and how is that benefiting you?**

Reduce resource waste and lowering overall cost of our cloud infrastructure

  ### 39. A cost-savings dream for cluster administrators

**Rating:** 5.0/5.0 stars

**Reviewed by:** Cameron L. | System Analyst, Internet, Enterprise (> 1000 emp.)

**Reviewed Date:** November 15, 2024

**What do you like best about Cast AI?**

Starting off -- CAST is extremely easy to install and configure. They offer scripted install, Helm charts, and Terraform modules which made it very simply to integrate them into our existing cluster bootstrapping process. 

Once deployed you instantly are met with dashboards that wil give you valuable insights into spend, usage, and security and enacting cost savings is as simple as clicking a button.

From that moment on they do all of the legwork in node selection and ensure that your nodegroups are running at the most efficient price-point and are scaling as-needed. Say goodbye to manually provisioning and manging node groups for good. 

Support has aslo been a high-point when working with CAST. In the rare occasion that we have encountered any issues they have been extraordinarily responsive and dedicate resources to assist with our problem until it is resolved, no matter the time of day or night.

**What do you dislike about Cast AI?**

The primary difficulty that we have encountered with CAST is cost justification. The tool costs significantly less money than it saves (and is by far a net positive), however, we find ourselves having to explain to leadership why our largest cost is now CAST. Ultimately this is easy to explain, it is jsut something that we encounter often.

**What problems is Cast AI solving and how is that benefiting you?**

CAST handles our node selection and provisioning for us entirely. We just install cast in clusters and walk away and can trust that our costs are as low as possible and that our node provisioning will run smoothy.

  ### 40. Simple to get going, fast and dedicated support will get you fully optimized

**Rating:** 4.5/5.0 stars

**Reviewed by:** Julius B. | CTO/Co-founder, Small-Business (50 or fewer emp.)

**Reviewed Date:** December 30, 2024

**What do you like best about Cast AI?**

Simple configuration to get going, user friendly interface. You get a safe way to test out the features in a "view" mode before committing to your purchase, and you can activate feature by feature easily. 

Deep customization using kubernets primitives and you can tune how aggressive the rebalancer is.

Dedicated support monitors your clusters metrics and utilization, and they let you know if you should consider rebalancing certain nodes, very quick reponse time and they are quick to find solutions if you run into problems.

**What do you dislike about Cast AI?**

still needs work on custom replica sets, for example ones controlled by Strimzi Kafka and ArangoDB.

**What problems is Cast AI solving and how is that benefiting you?**

Keeping costs down while still scaling based on the needs of the cluster.

  ### 41. Huge savings on our AWS cloud expenses!

**Rating:** 5.0/5.0 stars

**Reviewed by:** Ron G. | VP R&D, Mid-Market (51-1000 emp.)

**Reviewed Date:** October 10, 2024

**What do you like best about Cast AI?**

Cast does a great job at optimizing the workload, thus reducing the cloud costs. we were pretty optimized already and it still saved us around 30-40% of the total costs(!)

The team is very engaged and really care about our success. they are always there to answer questions and do deep dives when changes are made

Also they give very good transparency so you know where you stand

And I loved the onboarding process where they monitor your clusters and tell you how much money you could have spent, which was pretty accurate when we connected them. it was a smooth process, so implementation was really painless

**What do you dislike about Cast AI?**

Nothing specfic I dislike, there are always things to improve, but generally - I like the product and I like them as partners

**What problems is Cast AI solving and how is that benefiting you?**

We have millions of K8S jobs running weekly. We were using the AWS scaler and we had a feeling we were paying too much for what we were running. One of our DevOps engineers thought we really need to try a solution and recommended we tried cast. from the moment we started using them we say 30-50% savings on clusters instantly. 
The bin packing and better orchestration of jobs together to a great job at optimizing the use of compute resources and really saves you money
The only thing we regretted was that we waited so long

  ### 42. A Kubernetes scheduling tool that we were missing

**Rating:** 4.5/5.0 stars

**Reviewed by:** Nicolas H. | Lead SRE, Mid-Market (51-1000 emp.)

**Reviewed Date:** May 24, 2023

**What do you like best about Cast AI?**

The simplicity of installation and use of the platform. In about 20 minutes you have your Kubernetes nodes managed by cast.ai. It was really quick and easy to set up.

The configuration of the different node types is also very convenient and the cost tracking is very powerful.

**What do you dislike about Cast AI?**

Actually, nothing. The product corresponded totally to our needs and expectations. But if we really want to find something to complain about, we could talk about the price. The pricing per CPU can be disadvantageous in some cluster configurations I think. In our case, we managed to negotiate a fixed price.

**What problems is Cast AI solving and how is that benefiting you?**

Cast.ai allows us to easily track the cost of our clusters and the various Kubernetes applications and namespaces. And in terms of node scheduling it allows us to have Kubernetes nodes faster and better balanced than the basic scheduling of our Cloud provider. Scheduling is the feature that interested us the most, especially for setting up spot nodes (reduced rates) very easily.

  ### 43. A Kubernetes automation platform we were missing

**Rating:** 5.0/5.0 stars

**Reviewed by:** Danail S. | DevOps engineer, Mid-Market (51-1000 emp.)

**Reviewed Date:** September 05, 2024

**What do you like best about Cast AI?**

So we had issues in a small team managing a couple of clusters in different environment and managing them in cost effective way. We appreciate the ease of use and the efficiency gains CAST provides, allowing teams to focus on development rather than infrastructure management. We also significantly reduced cloud costs for AKS  in Azure. CAST is helping for managing cluster autoscaling and spawn optimal nodes. Also additional features like security scanning and giving potential vulnerabilities in our images helps a lot. The simplicity of installation of the platform, cost optimization ,security features , bin packing, cost tracking, workloads right sizing and many more makes the platform really brilliant. Also helping us to easily upgrade k8s from version to version. Even the features that we potenatially might need and are not yet implemented they listen and plan some feature request for them.
Last but not least is the awesome fast and accurate support from CAST team in case of issues.

**What do you dislike about Cast AI?**

I dont have any significant complains about CAST AI at this moment.

**What problems is Cast AI solving and how is that benefiting you?**

Recommendations and cost optimization. Reducing the cost of AKS clusters.
Automation bean packing and ease of upgrade for k8s versions.
Workloads right sizing.
Reight sizing of the nodes and especially spot instances.
Responsiveness of CAST AI's support team in case of issues.
Detailed usage patterns, allowing teams to make informed decisions about optimizations.
Security image scanning feature for Vulnerabilities of the images.

  ### 44. EC2 Worker Management Automated

**Rating:** 5.0/5.0 stars

**Reviewed by:** David N. | Senior Devops Cloud Infrastructure Engineer, Mid-Market (51-1000 emp.)

**Reviewed Date:** October 28, 2024

**What do you like best about Cast AI?**

Fairly simple to install, we used it's Terraform provider -- and the team onboarding with us actively addressed some minor issues from the provider on the fly (literal next day solutions +1).  Initially i was pretty skeptical and nervous about handing over scaling of EC2 to a third party - but after it was in play we saw DRAMATIC savings wherever it was installed with our many EKS clusters, and little to no impact to services hosted inside of them.  The impacts we had seen were from our own installations for PVC management, that we have since rectified and its been resilient since.  Totally worth checking out, highly recommended.

**What do you dislike about Cast AI?**

Workload optimization seems to strip out the CPU limits, and i dont see a means in the settings for it to brick that behavior.  There are annoations etc - but would prefer something also to be globally accessible to prevent that.  Additionally, node sizes work fairly well - but with worker consolidation we had some workers end up with 90+ pods on them -- and with our stack the resources aren't totally defined yet causing impact to other pods on the same ec2.  Restricting total IP count as an optional setting would be nice.

Problems we experienced were almost entirely due to negligence from our internal staff with kubernetes manifests however -- If those were configured properly it wouldn't even be mentioned.

**What problems is Cast AI solving and how is that benefiting you?**

Instead of static set workers or the generic cluster-autoscaler for kubernetes hosted in EKS, it provides a way to consolidate pods to ec2 so it can be more compacted.  This ultimately saved us a ton of money overall.

  ### 45. The perfect fit to manage your workloads

**Rating:** 5.0/5.0 stars

**Reviewed by:** Ricardo S. | CloudOps Engineer, Mid-Market (51-1000 emp.)

**Reviewed Date:** August 05, 2024

**What do you like best about Cast AI?**

- It allowed us to not worry about the size needed for EC2 instances. Without worrying about the resources that the pods used, Cast.ai was able to help us rightsize the instances. Without it this would be a manual job everytime something changed on the workloads, meaning that now we have more time to focus on the overall picture knowing that Cast.ai is there to manage the costs of our infrastructure
- Allowed us to quickly adapt and use different workloads for spot instances for example
- Easy onboard even with the free version that allows to have an immediate knowledge on how much can it be saved
- The possibility to use all the EC2 family types available with small configurations allowed us to quickly save and be ready for future growth and minimize possible cloud failures and lack of resources. For example if the configuration uses all the same family types of EC2 is probable that at some point in time there are not enough machines on the datacenter to provide the same service to multiple clients. Cast.ai allows to select the cheapest instances using filters if needed and always checking if the instances are available, if not, the next cheapest option is used
- Great support from the team with new features appearing constantly. Our feedback is listened :)

**What do you dislike about Cast AI?**

To be sincere nothing until now happened that I could say that Cast.ai is not a great product

**What problems is Cast AI solving and how is that benefiting you?**

- It greatly reduced the costs on our side I would say at least 50% depending on the workloads used and every cluster is different.
- With the possibility to predict if SPOT instances would be available we can minimize sudden disruptions on the server, that with a mix of spot instances can help even great cost reductions

  ### 46. Maximizing Cloud Savings Through Kubernetes Automation

**Rating:** 5.0/5.0 stars

**Reviewed by:** Vitalii B. | DevOps, Mid-Market (51-1000 emp.)

**Reviewed Date:** January 08, 2025

**What do you like best about Cast AI?**

CAST AI made Kubernetes cost optimization effortless. 
We saw immediate results, with significant savings and zero downtime during implementation.
Main key points:
- advanced node automation for node management and spot instance utilization
- simplicity usage with maximum savings in one package

**What do you dislike about Cast AI?**

I don't have any significant complaints about CAST AI. 
They have been a reliable partner throughout our collaboration.

**What problems is Cast AI solving and how is that benefiting you?**

The ability to automatically scale and optimize workloads has not only reduced our Kubernetes costs but also freed up our DevOps team to focus on innovation rather than infrastructure management.
By automating complex optimization tasks, CAST AI helps us avoid overspending on unused resources while maintaining seamless application performance.

  ### 47. A Kubernetes automation platform that helped us save on the cloud using Spot instances

**Rating:** 4.0/5.0 stars

**Reviewed by:** Cyril T. | SRE, Mid-Market (51-1000 emp.)

**Reviewed Date:** July 22, 2024

**What do you like best about Cast AI?**

-the interface is fairly clear and intelligible. The main options are available in the interface, making it easy to use the product.
- really effective for optimising costs, particularly with the use of Spots and the integration of advanced features (spot fail back, mixed instance type, etc.)
-Easy integration supporting Iac Tools like Terraform. 
-Really good support from the Team.

**What do you dislike about Cast AI?**

-The gains shown are not based on actual Azure costs, so they are slightly different. 
-Quota management could be improved. You discover that your quotas are not good after rebalancing. It would be smart to warn you beforehand. This could be done easily with IAM read permissions on the Quota part.
- Workload autoscaler on daemonset and statefulset. This functionality should be available very soon

**What problems is Cast AI solving and how is that benefiting you?**

We wanted a reliable, dedicated solution for optimising workloads on AKS clusters. Cast doesn't spread itself too thinly over a host of features, but concentrates on optimisation (gain + security) and does it quite well.
We didn't want to spend a lot of time administering AKS clusters in the optimisation part. 
We also wanted to know quite precisely how the costs were distributed within the clusters on different projects.
Instead of developing processes or solutions ourselves, we rely on expertise and premium support. Which is a considerable gain for us

  ### 48. CastAi Review

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Information Technology and Services | Mid-Market (51-1000 emp.)

**Reviewed Date:** March 06, 2025

**What do you like best about Cast AI?**

Easy to use UI. Consolidation of things at one place. Good cost savings and hibernation concept is really good.

**What do you dislike about Cast AI?**

Some machine types are not supported. So, we need to select different machine types for our products. Build an overall platform not for just gcp but include other future of cloud as well such as db optimisations etc.

**What problems is Cast AI solving and how is that benefiting you?**

Our costs have reduced significantly. Support is good, we get the response pretty fast if something goes wrong.

  ### 49. The overall experience with CastAI has been great.

The easy installation, Deployment and upgrade.
Expert and the blazing fast support.
Very intutive UI.
One among the best documentation. 
Seemless integration.

**What do you dislike about Cast AI?**

So far have not encountered anythign that can qualify a feature being irrelevant. 
Need more fine grain control to manage interdependant workloads.

**What problems is Cast AI solving and how is that benefiting you?**

We are using CASTAI primamrily to save overal cost. While using the product, it helped us identify data points to improvise and make it well architected. Reduced overal efforts and costs to develop and manage cost control mechanism.

  ### 50. Seamless Cloud Cost Optimization with CAST AI

**Rating:** 4.5/5.0 stars

**Reviewed by:** Aymen B. | Lead DevOps Engineer, Printing, Enterprise (> 1000 emp.)

**Reviewed Date:** August 07, 2024

**What do you like best about Cast AI?**

CAST AI has delivered immediate cost savings and simplified our Kubernetes management. The support team was exceptional during the integration process, ensuring a seamless and successful integration into our existing infrastructure. The security dashboard provides a lot of insightful info; yet I need to enable it in my clusters.
The good thing is that even when we're using CAST AI, we can still have the backup option of using the regular cluster-autoscaler.

**What do you dislike about Cast AI?**

The Terraform documentation lacks details on how to configure the different components; but the support team is there to help you out. Also, it takes time to get used to how to troubleshoot errors you might face during the setup.

**What problems is Cast AI solving and how is that benefiting you?**

- Cloud cost reduction
- Cluster autoscaling
- Efficient resource utilization
