Manmohan Rao - PeerSpot reviewer
Associate Vice President at Hitachi Systems India Private Limited
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.

Identifies and eliminates overprovisioning of expensive resources like storage, highly scalable and offers performance
I like the overall product because I can select what monitoring should be enabled and whatnot. In our case, we really focus on performance because it's clear that the price is related to most performance setups. So the more performance, the more expensive. So we look into the performance that the customer needs, and then based upon that feedback from the remote control, we change the parameters. And even the end user will not notice it is not using it, so we just make money without any impact on the end users.

Quotes from Members

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

Pros

"CoreStack helped me to manage the Cloud Security Posture Management across different clouds, including AWS, Azure, and other cloud providers, allowing me to view all the policies and misconfigurations in one centralized console rather than going to multiple consoles to look for violations and take actions, which was really helpful for me."
"Currently, I think CoreStack is the best FinOps tool available in the market, which is why we are using it."
"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."
"It offers a detailed examination of your cluster, including the types of instances utilized, allocated CPU and RAM, and resource distribution for specific applications."
"The price is reasonable, considering the value it delivers."
"I mostly like the dashboards."
 

Cons

"I believe the multi-tenancy feature is present, but if it could be improved and secured further, that could be beneficial."
"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 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 am not currently using CoreStack, as I moved away from CoreStack due to a lot of issues with accuracy."
"Faster monitoring could potentially improve overall stability in the production environment."
"There is a significant potential for enhancing it through the incorporation of advanced technologies like AI and generative AI."
"The integration with other solutions could be improved."
 

Pricing and Cost Advice

Information not available
"The cost is cheap. Kubecost has an open-source core."
"The cost of the tool may seem nominal compared to the potential savings in infrastructure expenses."
"The real savings come from using Kubecost features like autoscaling and serverless functions to optimize your resource usage. If you treat it like a data center migration without fine-tuning, it might cost more."
