Valuable Features

CoreStack offers significant value through well-architected actions across multiple clouds. Users appreciate a single interface for multi-cloud cost management, saving time and enhancing efficiency. Enhanced visibility into unused resources and automated remediation are key highlights. CoreStack improves compliance, reduces risks, and optimizes costs. Accurate recommendations on AWS services like RDS and EC2 drive financial savings. Centralized compliance and performance reports enhance operational excellence and customer satisfaction.
  • "Currently, I think CoreStack is the best FinOps tool available in the market, which is why we are using it."
  • "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

CoreStack requires enhancements in segregating reserved instances for cost allocation, improving security tools, and automating operational tasks. Stability and UI responsiveness need attention, as well as native integration with SOAR platforms and customization of executive dashboards. Reporting accuracy for cost optimization and visibility in multi-tenancy are also areas of concern. More integrated features and user-specific permissions could benefit users managing multi-account environments.
  • "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."
