Valuable Features

  • "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."

Room for Improvement

  • "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%."
  • "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."
