Automation has optimized our kubernetes costs and continuously improves cluster efficiency
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.

Cloud Ops Lead at a tech vendor with 10,001+ employees
Gained multi-cloud cost visibility and have optimized spend with detailed reports and rightsizing
The IAM feature is something that we struggle with using. IBM, the company that runs Cloudability, released the Groups feature back in the summer of 2025. While Groups can be used in some parts of the tool, it can't be used across the entire tool. I've found that Groups is basically unusable because if it can't be used everywhere, you would have to run both group-based access control and direct user-based access control at the same time, which doesn't make any sense. The Groups feature has improved over time, but it's still not something we feel we can use on an everyday basis, so the IAM section remains an issue right now. Most of the tool is very well-functioning and developed, and that's the only real improvement area that we've seen.

Pros

"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."
"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."
"Since using CAST AI, we have achieved approximately 30 to 40 percent reduction in our Kubernetes infrastructure cost."
"Our clients are now able to get a better insight into their AWS accounts."
"Cloudability's customizable alerts help me maintain budgetary goals by providing recommendations and alerts on slot usages."
"It justifies the cost and is worth it, and we loved the experience of purchasing this solution through AWS Marketplace as it is very intuitive and cost-efficient."
"Cloudability takes care of identifying and managing the cloud."
"If you are looking for a seamless, simple to use, and in-depth cloud billing analysis tool, Cloudability serves all these purposes."
"Each user can have their own dashboard that they want to consume. Instead of having to share one dashboard for multiple users, you can create individual views for each user to view, and that view will contain only their own accounts, which allows for separation of data."
"All the tagging and mapping, which helps to create some virtual tags are useful features."
"The most crucial feature in reducing my cloud costs has been the rightsizing recommendations, along with the dashboards that track reserved instance spending coverage and utilization. As for Cloudability's integration with our existing cloud infrastructure, it's not integrated directly into our AWS infrastructure but rather reads and pulls data from it, providing valuable insights and analysis for cost management."
 

Cons

"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."
"The limitations of CAST AI include reporting and customization options."
"I would like the API functionality to improve. The update time after uploading data could also be improved."
"We have dealt with a few technical support people where we ask for one thing and they might not deliver straightaway. It seems like they are a stretched across multiple customers."
"Right now, I don't think that they do good predictions at all."
"In general, I feel Cloudability wasn't able to support many resources."
"The API is not well-documented. It is not straightforward and difficult to use. This needs to be improved, as it is very difficult for our developers to develop automation around it."
"There are also some limitations with the dashboards and data representation in Cloudability."
"The IAM feature is something that we struggle with using."
"There is always room for improvement in education and training."
 

Pricing and Cost Advice

Information not available
"Cloudability is a bit expensive."
"My team is one of the most expensive teams, and we look at it quite a bit. We have probably easily saved around $400,000 USD a year."
"We have seen ROI with the reserved instances, and having the ability to predict what reserved instances you can get. We can save tens of thousands of dollars, and hundreds of thousands of dollars in some cases."
"The price of the license or the usage is a percentage of the top consumption. So it varies from year to year."
"It justifies the cost and is worth it."
