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.

Digital Marketing, Marketing Technology & Analytics Architect at a manufacturing company with 10,001+ employees

Gained clear cost visibility and forecasting but still needs finer insights using resource tags

Cloudability offers excellent features including trends, graphs for cost utilization, and forecasting capabilities. The forecasting feature has helped me understand how the resources are utilized and how the cost is burned, and then I use it to make changes to keep the cost in control. Cloudability has positively impacted my organization as it helps us understand cost utilization, make corrections, and understand the forecasting of the cost. It has made reporting much easier.

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."

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

"It has already given us insight into how to optimize. So, we are now ramping up steadily its usage."

"The support from IBM is fantastic"

"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."

"Transparency and visibility are the key features."

"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."

"The most valuable feature of the solution is its ability to create reports and dashboards."

More Cloudability pros

Cons

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

"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."

"Enhancements could be made in the user interface and customization, and leveraging GenAI would be an area for improvement in Cloudability."

"I would like the API functionality to improve. The update time after uploading data could also be improved."

"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."

"They can improve the custom range of the network."

"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."

"Cloudability needs to focus on more cloud providers."

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

Pricing and Cost Advice

Information not available

"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."

"It justifies the cost and is worth it."

"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."

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