Automation has optimized Kubernetes costs and right-sizing cuts manual cluster work

CAST AI helps us with automated node provisioning, workload right-sizing, intelligent auto-scaling, and overall cost visibility of the containerized systems that we have on the cloud. The best features CAST AI offers are the Kubernetes auto-scaling mechanism, continuous analysis of the pod-level CPU and memory usage, and ensuring that workload right-sizing is being done and our nodes are not over-provisioned. Identifying inaccuracies in the resource request is what we find quite useful with CAST AI. It definitely saves time and money as well, along with peace of mind because CAST AI continuously analyzes the pod-level CPU and memory usages. This helps us to optimize the request and the limits adjustments on our usage pattern, and overall, right-sizing improves the packing and reduces the wasted compute that we have in the cloud. In terms of overall impact on the organization, CAST AI has definitely helped us optimize our Kubernetes resources and given us automation capabilities. It is definitely helping us reduce the manpower and overall compute which is wasted. We can definitely save these using CAST AI. We will be notified upfront and proactively about any wastages that are happening, or any cost leakages that are happening in our system.

Enterprise Cloud Operations 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.

Quotes from Members

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

Pros

"We observed a 20 to 30% reduction in Kubernetes infrastructure cost, node utilization is improved, and we could see a 60 to 70% reduction in our manual cluster optimization efforts that we used to put initially."

"One of the standout features of the solution is its groups and views functionality. The solution is highly-stable. The solution is highly-scalable. The customer support is good. They can be easily contacted. The initial setup is straightforward. It's an excellent tool, especially when dealing with multiple clouds. It streamlines the process, eliminating the need to check each cloud individually."

"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."

"Cloudability takes care of identifying and managing the cloud."

"Cloudability has positively impacted my organization as it helps us understand cost utilization, make corrections, and understand the forecasting of the cost."

"Cloudability's customizable alerts help me maintain budgetary goals by providing recommendations and alerts on slot usages."

"It provides us visibility, then we can turn around and can give the leadership team more information, which we could not previously give them."

"Transparency and visibility are the key features."

"The support from IBM is fantastic"

More Cloudability pros

Cons

"The documentation of CAST AI can definitely be improved for first-time users."

"The IAM feature is something that we struggle with using."

"Right now, what we're doing is we are manually putting the data in it, which is something which we don't like about Cloudability."

"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."

"The dashboard needs to include more graphs per team to show what individual teams are spending in a given time period."

"I wish there was a feature to temporarily remove certain recommendations from the list for teams that couldn't implement them immediately. I believe Cloudability could improve its automation functionality and enhance cost allocation modeling."

"There are also some limitations with the dashboards and data representation in Cloudability."

"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."

"We would like them to have a linear regression, so we can be predictive for budgets, allocations, and the year's follow ups. We also want to have a longer window of analytics with better certainty that our workload will fit the model, not just in a two week window."

Pricing and Cost Advice

Information not available

"Cloudability is a bit expensive."

"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."

"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."

"It justifies the cost and is worth it."

"The price of the license or the usage is a percentage of the top consumption. So it varies from year to year."
