Associate Vice President at a tech services company with 10,001+ employees

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.

DevOps & FinOps Engineer at a tech vendor with 501-1,000 employees

Gain visibility into Kubernetes clusters and optimize resource allocation based on historical data

I think they should focus more on Kubernetes features that allow on-the-fly resource allocation without the need to restart services. They should implement this in their autoscaler to make it more useful in scenarios that require immediate scaling up or down. They should also offer more options for visualizing graphs in different ways, such as tabular views.

Quotes from Members

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

Pros

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

"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."

"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."

"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."

"PerfectScale made our Kubernetes optimization effortless; it found wasted resources, lowered our cloud costs, and improved performance almost instantly."

"The cluster and workload autoscaler gives us the ability to have control over all the workloads' resources instead of managing them one by one."

"Automated resource optimization using different policies based on the environment enabled the organization to achieve infrastructure cost savings."

Cons

"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."

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

"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%."

"With their in-place optimisations, stateful set optimisation would be a great addition."

"I think they should focus more on Kubernetes features that allow on-the-fly resource allocation without the need to restart services."
