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.

Cost reports have driven accurate AWS workload optimization and continue to guide savings

I can suggest improvements for CoreStack, especially regarding reporting periods. I noticed that some of the cost optimization reports generated potential savings while considering systems that have only maximum utilization of 1% or 2%. The recommendations made in CoreStack to delete a machine have the potential to generate major cost savings, but such machines should not be listed for deletion if they have maximum CPU utilization of 1%. I have concerns about needed improvements primarily regarding AWS. If a customer is running ten virtual machines and one machine has a maximum of 1% utilization, it is considered as an idle instance in the report, which completely ignores that particular machine. This should not be the approach.

Quotes from Members

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

Pros

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

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

"Transparency and visibility are the key features."

"We use the product to get a detailed level of transparency on the cloud strengths."

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

"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."

"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."

"The pricing isn't too expensive."

More Cloudability pros

"CoreStack has positively impacted my organization by saving hours of time for reporting—for example, the governance report which my employees used to take at least four hours for one customer, and since I'm sending out 20 reports every month, that equates to 80 hours, thus saving me two man-weeks every month and approximately $8,000 in pure savings if I estimate $100 an hour for my architect."

"My advice for others looking into using CoreStack is that anyone who is looking to optimize their workload cost for public cloud services should start using CoreStack because of the reports and granularity it produces to optimize cost, which will benefit them."

"Mainly through improved cost visibility and optimization with CoreStack, we have achieved a good ROI, and for some customers we were able to achieve more than forty percent cost savings by identifying unused and idle resources in their accounts, leading to significant cost savings after we completed the cleanup of those resources."

"Currently, I think CoreStack is the best FinOps tool available in the market, which is why we are using it."

Cons

"I would improve the integration, or the preparation of the integration, for a complex environment."

"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."

"Cloudability needs to improve on data collection from cloud sources."

"Cloudability needs to focus on more cloud providers."

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

"In general, I feel Cloudability wasn't able to support many resources."

"My experience with pricing, setup cost, and licensing was adequate, but it could be made better."

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

More Cloudability cons

"I noticed that some of the cost optimization reports generated potential savings while considering systems that have only maximum utilization of 1% or 2%. The recommendations made in CoreStack to delete a machine have the potential to generate major cost savings, but such machines should not be listed for deletion if they have maximum CPU utilization of 1%."

"I believe CoreStack already has very good features in the governance and security parts, but stability can definitely be improved."

"I give it an eight because, as I mentioned, a few things from the billing operations need to be added, and we need more security features, particularly since the market is increasingly demanding better security tools for cloud management platforms, including cloud security posture assessments."

Pricing and Cost Advice

"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."

"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."
